Flame Detector for hazardous area.

Uses four infrared sensors to help distinguish hydrocarbon fires from non-flame background radiation.

A new flameproof model for the Rosemount™ 965 Flame Detector, adding hazardous-location certification for applications where reliable hydrocarbon flame detection is required has been announced. The new model combines QuadSense™ technology, factory-calibrated-for-life operation, broad integration options and rugged enclosure protection to support fire protection strategies matched to application needs.

“Customers need flame detection technology that aligns with the risk, environment and operational needs of each application,” said Evgeny Rivkin, flame and gas product manager with Emerson’s measurement instrumentation business. “This new flameproof model expands the Rosemount 965 offering for hazardous locations, helping teams balance detection performance, resistance to nuisance alarms and routine calibration requirements.”

The new flameproof model helps customers extend the Rosemount 965 to hazardous locations while maintaining a practical balance of detection performance, reduced routine calibration and deployment flexibility.

QuadSense technology uses four infrared sensors to help distinguish hydrocarbon fires from non-flame background radiation, supporting reliable detection and resistance to nuisance alarms. Under specified conditions, the detector can detect hydrocarbon fires at distances up to 45 metres (150 feet) with response typically in less than five seconds. Five selectable sensitivity levels help users align performance with application needs.

The Rosemount 965 is factory calibrated for life, helping reduce recurring calibration routines. Infrared built-in test capabilities continuously verify optics and electronics integrity, supporting confidence between manual inspections. Multiple output options, including HART® connectivity, support integration with standard communication infrastructures, while universal wiring helps simplify specification and streamline sitewide deployment. IP66 and IP68 enclosure protection supports performance in demanding operating environments.

The new flameproof model can be applied in environments often found in oil and gas facilities, chemical and petrochemical plants, storage tank farms, hazardous materials storage areas and explosives or munitions sites. The Rosemount 965 also supports non-hazardous and light-industrial applications such as transportation infrastructure, public buildings, cable tunnels, semiconductor facilities, warehouses and other sites where dependable hydrocarbon flame detection is needed.

Proven and popular gas detection.

Versatile, high-performance gas detection with easy deployment

There are many prerequisites when it comes to gas detection, not least maximum flexibility, increased performance and minimal installation costs. Add in modern expectations such as smart features and the ability to detect explosive, toxic or asphyxiant gases, and the list of potential solutions soon becomes short. Prominent among the choices, however, is the proven and popular iTrans 2 fixed gas detector from Teledyne Gas & Flame Detection.

Offering smart sensor capabilities that support an intelligent electronics platform, the iTrans 2 provides one or two points of detection from a single head for maximum flexibility, with both readings shown on the standard-issue, LED and display. Gas sensors are mountable directly to the transmitter, or remotely.

For the detection of explosive and toxic gas, or oxygen, the iTrans 2 accepts infrared, catalytic bead or electrochemical sensors. Specifically, in addition to the LEL (lower explosive limit) sensor range, the iTrans 2 is configurable with a 0-100% volume methane infrared sensor for bio-gas applications and CO2 infrared sensors ranging from 0.5% to 100% volume. All are pre-calibrated using smart technology to enable automatic sensor recognition and data transfer. The device displays sensor life data automatically after each calibration.

Offering cable-saving and time-saving installation, the iTrans 2 is suitable for almost any application via common configurations that include 3-wire (4-20mA) and 4-wire (digital ModBus) models. Both allow for full utilisation of the gas detector’s features and options, and use with all iTrans 2 sensors.

iTrans 2 offers analogue 4-20mA and digital RS-485 Modbus (9600 baud) outputs. The HART communication protocol is optional, enabling remote communication across the 4-20mA signal for diagnostics, commissioning and calibration. A simple magnetic wand further aids ease of use by allowing full transmitter configuration and calibration without opening the explosion-proof housing.

The housing comes as standard in epoxy-coated aluminium, with an optional 316 stainless steel version available for corrosive environments. Operating temperature is -40°C to +75°C. Although this robust specification is ideal for many heavy industry applications, the iTrans 2 is equally at home in smaller systems and boiler rooms, for example. Indeed, this tried and tested gas detector is suitable for sectors that extend from oil and gas, offshore drilling, utilities and petrochemical, through to water and wastewater treatment, and food and beverage production. Certifications include CSA, ATEX, IECEx, INMETRO, CCC and China Ex.

Notably, the microprocessor-controlled transmitters are capable of plug and play, stand-alone operation or multi-point system configuration. The monitor’s stand-alone operational ability arrives courtesy of optional on-board relays that can activate alarms, horns or fans, and can also shut down a system without the need for return wiring to a central control panel.

With so much versatility and functionality, whatever the application or requirement, the iTrans 2 from Teledyne Gas & Flame Detection has already proven itself as the market’s most comprehensive and competent tool for the job.

Gas detectors protect workers and property.

Gas detectors trigger alarms for toxic and combustible gases across wide areas.

Two new open path gas detectors have been introduced by Emerson which increase safety and reduce downtime by offering performance reliability over wide areas in extreme environments and an easier, faster installation and commissioning process. Extreme environments include both heavy vibration conditions and operating temperatures ranging from -55C (-67F) up to 65C (149F) degrees commonly found in the oil and gas, refining, chemical, mining and large-scale refrigeration system operations.

The Rosemount™ 935 Open Path Combustible Gas Detector uses infrared technology to detect a wide range of highly combustible hydrocarbon gases, including methane, propane and ethylene. In the oil and gas industry alone, 22% of all fatalities come from explosions (combustion or fire) and exposure to hazardous gases, according to the latest statistics from the CDC’s (Centers for Disease Control and Prevention) US National Institute for Occupational Safety and Health.

The Rosemount 936 Open Path Toxic Gas Detector uses ultraviolet technology to detect hydrogen sulphide and ammonia, two of the most common toxic gases in industrial facilities. The US Occupational Safety and Health Administration considers hydrogen sulphide immediately dangerous to life and health at 100 ppm. Ammonia irritates skin, eyes, nose and the respiratory tract at 130 ppm. Both gases are fatal after exposure at certain levels.

Leveraging xenon flash technology, the Rosemount 936 enables greater installation flexibility versus the tunable diode laser (TDL) technology which needs perfect alignment between beam and receiver for high reliability. With nearly twice the tolerance for misalignment than TDL, users can save up to 30% of installation time and streamline project schedules.

Open path detection technology uses a source and a detector. The source sends a modulated light beam across the monitored space, and the detector senses the amount of light absorbed by the presence of gas. This approach provides a high degree of coverage across wide areas up to 200 metres (656 feet) in length with accurate measurement, even if the toxic or combustible gas cloud is drifting at any point between the devices or when 95% of the light beam is obscured by fog, rain or smog. The system also will alert if the path is blocked completely by a physical obstruction.

Both Open Path Gas Detectors can be used in combination with Emerson’s full portfolio of flame and gas detection products as part of a comprehensive safety system to ensure quick and positive detection. Many facilities benefit from the use of multiple technologies to achieve maximum protection.

Flammable gas detection.

Crowcon Detection Instruments has unveiled an important innovation in fixed gas detection with the launch of the world’s first fixed detector with a Molecular Property Spectrometer ™ (MPS™) sensor. The Nevada Nanotech MPS™ sensor has been added to its Xgard Bright fixed gas monitor, which is set to drive up standards in gas detection and safety, while driving down the cost of ownership.

Developed by of NevadaNano, the MPS™ sensors represent the new generation of flammable gas detectors. MPS™ can detect up to 15 flammable gases (further gas species being characterised) at once, quickly and to a very high degree of accuracy. 

Until recently, anyone who needed to monitor flammable gases had to select either a traditional flame sensor detector with a pellistor calibrated for a specific gas (and multiple pellistors in multi-species environments), or an improved capability sensor using infra-red (IR) which also requires a separate sensor to be calibrated for each gas. 

While these remain very helpful solutions, they are not always ideal. For example, both types of sensor require continual calibration and bump testing and pellistors may be damaged by contaminants (known as ‘sensor poisoning’) or harsh conditions. In some environments this means that sensors must be continually changed, which is costly in terms of both money and downtime.  Also, IR technology cannot detect hydrogen, and both IR and pellistor detectors sometimes incidentally detect other (i.e. non-calibrated) gases, giving inaccurate readings that may trigger false alarms.

In contrast, MPS sensors quickly detect multiple gases simultaneously with no need for in-field calibration. Because the Xgard Bright’s MPS™ sensor is precise, does not drift and does not require a correction factor, it swiftly, clearly and correctly informs the user how close the ambient gas levels are to the lower explosive limit (LEL). This is referred to as the ‘True LEL™’ reading.

What is more, MPS™ sensors cannot be poisoned and require no calibration or bump testing throughout their lifespan, which generally exceeds five years. They are self-monitoring and will automatically alert the user to any malfunction. That spares users the cost of labour, peripherals and downtime, and means that workers no longer enter hazardous areas to check on the gas detectors

It also offers the possibility of huge savings for sectors that find pellistor sensors costly and prone to failure, but which have not, until now, had any realistic alternative.

Position sensitive detectors.

Laser Components now offers an additional extension to SiTek's successful SEEPOS signal processing system. With the new switch, up to four position sensitive detectors (PSDs) can be connected. It is up to the operator to decide which detector is to be evaluated. The robust, user-friendly design with a multideck rotary switch and D-SUB9 connectors makes the switch particularly attractive for use in laboratories.

With SEEPOS, SiTek offers a versatile and easy-to-use tool for processing PSD signals. The software gives the user access to all important parameters such as PSD bias voltage, amplification factor, and the use of analog and digital filters. The data collected by the PSD electronics is transferred to digital signal processing via high-speed USB data transfer. The position of the light spot is continuously displayed both two-dimensionally along the X and Y axes and one-dimensionally along the X or Y axis. The result is a powerful system for measuring distances, heights, positions, movements, and vibrations.

Gas detector validated!

United Electric Controls has announced that its Vanguard WirelessHART Gas Detector is now HART Registered. This registration ensures that all WirelessHART users will be able to add Vanguard device drivers the next time they update their device descriptor (DD) libraries. It also assures users that they can add Vanguard systems to existing WirelessHART networks, seamlessly and securely.

"Vanguard WirelessHART gas leak detectors can be dropped into any WirelessHART network using a secured network I.D. and join key. The unit automatically detects the sensor type and configures it automatically. This saves additional setup time and effort and the HART certification gives our users one more layer of confidence that this plug-and-play interoperability will be achieved seamlessly,” said Chris Frail, Vanguard product manager for United Electric Controls.

The HART communication protocol is the largest digital communications technology deployed in the process industries with more than 40 million field instruments supporting HART technology installed worldwide. The FieldComm Group owns the HART specifications and provides specification development and training, as well as device registration.

Eliminating the need for a wired infrastructure can reduce gas leak detector installation costs by as much as 50 percent and installation time by almost 90 percent, making it much easier and affordable to extend safety coverage. Further contributing to economical safety coverage expansion is Vanguard lithium metal battery technology and intelligent power management circuitry, which extend battery life well beyond five years, establishing the Vanguard detection system as the benchmark in battery-operated wireless gas detection.

The Vanguard WirelessHART detector uses a system of field-interchangeable gas sensor modules to detect methane (CH4), hydrogen sulfide (H2S), carbon monoxide (CO), ammonia (NH3), and non-methane hydrocarbon gases.

Gas detector for offshore platform operations.

United Electric Controls, a leading producer of safety, alarm and shutdown technology, is demonstrating the latest version of its Vanguard WirelessHART gas detector, with new features of value for offshore platforms.

Magnetic mounting and adjustable pipe clamp options enable offshore operations teams to increase detection of toxic and combustible gases. High stability and high-resolution offerings improve reliability and accuracy of detection and the addition of carbon monoxide (CO) detection to existing wireless hydrogen sulfide (H2S) and methane CH4 detection reduces cost of compliance with air pollution regulations.

"By eliminating the need to install and locate wiring, wireless technology reduces installation cost by as much as 90 percent and preserves valuable platform space. The new capabilities of the Vanguard WirelessHART detector make it even easier for platforms to benefit from wireless gas detection by giving them more flexibility to locate detectors on the platform, and the CO detection capability helps control one of the largest sources of offshore air pollution,” said Andrew Liptak, United Electric Controls Product Manager for Gas Detection.

The new Vanguard WirelessHART gas detector version also features its new FLEXmountTM installation, which augments Vanguard standard mounting with magnetic and universal options. The magnetic option enables installation on I-beams without drilling. The universal option uses adjustable clamps that enable installation on pipes from 3” to 12” in diameter, without a hot work permit.

Among the locations in which gas detection might be located on a platform are mud logging units, mud pit room, drilling derrick and mud gas separator, and well-test areas, or wellheads, where H2S is prevalent. Locating near gas flaring locations, venting storage tanks, dehydrators, and pig launchers can detect CH4 releases, and locating near burners can detect CO emissions.

Vanguard WirelessHART version 1.2 also includes the following new features:

• New WiHART communication accessories, which enable users to extend system range, get more out of their installed HART instruments by receiving WirelessHART data via 4-20 mA inputs, and further extend range with powered repeaters.
• A new touchscreen configurator, which streamlines onboarding of the gas monitor to a WirelessHART network.
• Upgraded diagnostic software, which detects and pre-warns of system faults, providing more visibility into sensor messages, more ways to code the status of the signals and fewer false alarms.

The Vanguard WirelessHART Gas Detector version 1.2 is available immediately, supporting interchangeable detection heads for hydrogen sulfide (H2S) and methane (CH4) as well as carbon monoxide (CO). Beta testing is now underway for ammonia (NH3) detection heads.

Tiger cleans up after fires!

The chemical industry has recently seen four major incidents take place. On March 17th 2019 two ITC tanks caught fire in Deer Park,  (TX USA), with five more catching fire just 12 hours later. A few days later, an explosion at the Xiangshui chemical plant resulted in the death of 78 people while severely injuring 94. On April 2, a leak caused a fire at the KMCO plant in Crosby, (TX USA), severely injuring two and killing one. In addition, a waste materials plant caught fire in Campbellfield, a suburb of Melbourne (AUS).

As a result of the explosion at the ITC tank farm, an Ion Science Tiger Select hand held gas detector is currently being used in Deer Park to assist with the clean-up process. The instrument is specifically seeking traces of benzene, which is highly toxic. A Tiger has also been purchased by members of the local community who are concerned with their own health, allowing them to monitor the air quality.

These recent incidents have seen the intervention of local government agencies and compliance with environmental and health and safety legislation, resulting in a series of violations for clean air, clean water, and environmental quality that include failure to comply with emissions rate standards, conduct stack tests, and the discharge of hazardous waste.

Although it is not yet confirmed what has caused these incidents to occur, it is speculated to have been caused by leaking materials.

In these circumstances a fixed monitoring device, such as the Titan fixed benzene specific detector or Falco fixed volatile organic compound (VOC) detector from Ion Science, is capable of continuously detecting VOCs, including benzene, ultimately preventing such catastrophic events.

The Tiger Select is a revolutionary hand held gas detector with two mode operation for the rapid and accurate detection of benzene and TACs. Utilising the high output Ion Science 10.0eV monitoring system, a reading for TACs is seen immediately on start-up. Should TACs be detected, a benzene pre-filter tube can be easily attached to ensure rapid detection and selective measurement of benzene.

Ion Science offers an array of advanced instruments that will detect and monitor a range of VOCs, including the handheld Tiger series, the Cub personal VOC detector and the Falco fixed PID detector which utilises typhoon technology, allowing effective operation within humid and harsh environments.

Photoionisation detector.

Ion Science has launched its ‘world first’ FalcoTAC fixed photoionisation detector (PID) with 10.0eV lamp for fast and reliable detection of highly toxic total aromatic compounds (TACs), including benzene, in high humidity environments. Designed for plant-wide safety and the on-going protection of workers in global petrochemical and oil & gas applications, the new FalcoTAC instrument also boasts the company’s innovative typhoon technology for unrivalled accuracy in condensing atmospheres and extreme weather conditions.

Aromatic chemical compounds produced by oil refineries and petrochemical plants form the building blocks for numerous important materials including dyes, detergents, solvents, adhesives, plastics, synthetic rubbers and pharmaceuticals. However the TACs produced in these environments such as benzene, toluene and xylene isomers, are also highly toxic.

Utilising the proprietary high output Ion Science 10.0 electron volt (eV) detection system, the new FalcoTAC volatile organic compound (VOC) monitor offers fast response times and the best possible protection for plant personnel, giving early warning of any harmful levels of exposure to hazardous TACs, including benzene.

Simple to install and operate, the FalcoTAC features an external intrinsically safe sensor for quick and easy servicing without the need for a hot work permit, and can be serviced and calibrated in a hazardous environment without having to remove the power.

Their advanced typhoon technology prevents condensation forming on the sensor which helps to stop the FalcoTAC short circuiting and make it ideal for harsh conditions and wet outdoor environments, without the need for weather enclosures.

By incorporating Ion Science’s market-leading PID sensor and patented fence electrode technology, FalcoTAC does not experience quenching of response due to humidity in the ambient air. This increased resistance to humidity and contamination ensures ultimate reliability in the field, as well as considerably reduced drift issues and extended run time.

The unit is operated via an intuitive user interface with OLED display and five magnetically activated switches – up, down, left, right and enter – which are back lit to help confirm the correct button is being pressed. For added convenience, safety and ease of use, brightly coloured red, amber and pulsing (optional) green status indicators are clearly visible in sunlight allowing checks to be conducted from a distance.
The FalcoTAC utilises a diffusive sample technique which ensures less contamination issues than pumped systems and reduced lamp cleaning and servicing requirements. Pumped models are available for applications where a sample needs to be drawn to the unit.

The FalcoTAC 10.0eV is available offering a detection range of 0.01 – 50 parts per million (ppm).

The explosion proof enclosure is certified to EX d IIC T4 II and the external sensor to EX ib IIC T4 Gb II. A 4 – 20 mA analogue output enables FalcoTAC to be easily integrated into a DCS control system to give warning or control of high VOC levels in the working environment. Two relay outputs means it can be connected remotely plus RS485 output with Mobus protocol included as standard allows the instrument to be connected to a network.
