From weaving to optical sensors.

The 55-year success story of Leuze electronic began with the "cono-pack", an electromechanical packaging machine. With the development of what at the time was the world's smallest reflex head, the key step into the market of industrial automation was taken. Numerous innovations followed. For example, the ASi bus is a Leuze electronic invention, as is the safe ASi. Safety monitors of a wide variety of labels come from the production facilities of Leuze electronic.

The company was directly involved in the development of the I/O link and is also playing an active role as a driver and pioneer of Industry 4.0. Clear focusing and differentiation has turned Leuze electronic into an expert in usability, industrial interfaces and communication and connectivity. Today, the company's main focus is on the areas of intralogistics, the packaging industry, machine tools and the automotive industry, as well as laboratory automation.

The product range of Leuze electronic includes switching and measuring sensors, identification systems, solutions for image processing and data transmission and also occupational safety components and systems. Many years of double-digit growth have meant not only an increase in turnover figures, but also the number of employees. Today, more than 1,200 sensor people at 22 locations are involved in development, production, sales and service – supported by more than 40 sales partners around the world. Leuze electronic demonstrates its consistency in the creation of new jobs.

• Leuze is looking for specialists in all areas, from skilled production workers to product managers and national and international sales managers. Growth also means that more space is needed. Which is why the company will continue to invest in new international facilities. At its headquarters in Owen/Teck, (D), not only additional office space and new staff parking places are currently being created, investments are also being made in the production and logistics departments.

London's clean air!

London Mayor Sadiq Khan has launched a new, street-by-street monitoring system that will help to improve that capital’s air quality. From July 2018, and operating for a year, London will benefit from what is being described as the world’s most sophisticated air quality monitoring system. A consortium involving academia, an environmental charity, and commercial partners will install a network of 100 multiparameter AQMesh air quality monitors, whilst also operating two Google Street View cars that will map air pollution at an unprecedented level of detail.
Air Monitors will supply the AQMesh pods and a comprehensive suite of analysers that will be fitted to the Google Street View cars. In addition, Air Monitors will be responsible for the wireless collection of data, so that air quality can be visualised and mapped in almost real-time. Working closely with the Greater London Authority, the project will be run by a team of air quality experts led by the charity Environmental Defense Fund Europe, in partnership with Air Monitors Ltd., Google Earth Outreach, Cambridge Environmental Research Consultants, University of Cambridge, National Physical Laboratory, King’s College London and the Environmental Defense Fund team in the United States.

Air Monitors Managing Director Jim Mills says: “It is difficult to underestimate the importance of this project – traditional monitoring networks provide essential information to check compliance against air quality standards, but this network will be ‘hyperlocal’ by which we mean that it will deliver street-level air quality data, which will be of tremendous interest to the public and also enable the effective assessment of air quality interventions.

“The Google Street View cars will take readings every 30 meters, helping us to find pollution hot-spots, so that AQMesh pods can be positioned in these locations. However, the pods are wireless and battery-powered, so they can also be quickly and easily fixed to lamp posts in other sensitive locations such as schools.”

In addition to nitrogen dioxide and particulates, which are the pollutants of greatest concern, the pods will also measure ozone, nitric oxide, carbon dioxide, temperature, humidity and pressure. Data will be automatically transmitted to Air Monitors’ cloud-based data management system, which can be accessed by PC, tablet or smartphone.

The monitoring data will provide baseline air quality data that will be essential in the assessment of mitigation measures, particularly in London’s expanding ultra-low emission zone. For example, on 20th June 2018, Sadiq Khan, announced the creation of the largest double-decker electric bus fleet in Europe, and the new monitoring network will enable the assessment of this initiative’s impact on air quality.

“This project will provide a step change in data collection and analysis that will enable London to evaluate the impact of both air quality and climate change policies and develop responsive interventions,” said Executive Director for Environmental Defense Fund Europe, Baroness Bryony Worthington. “A clear output of the project will be a revolutionary air monitoring model and intervention approach that can be replicated cost-effectively across other UK cities and globally, with a focus on C40 cities.”

Mark Watts, C40, Executive Director said: “Almost every major city in the world is dealing with the threat of toxic air pollution, which is taking an incredible toll on the health of citizens, public finances, quality of life and contributing to climate change. London is already a world leader in responding to this global threat and with this initiative it will set a new global standard for how street level air quality monitoring can inform strategic policy making. Cities across the C40 network and around the world will be watching closely to understand how this monitoring can deliver cleaner air for their citizens.”

Efficient connections for the Ex zone.

In environments where there is a high explosion risk (known as Ex zones), connectors must fulfil special safety requirements. Here Howard Forryan of Harting discusses how these challenges may be met.

Harting offers a range of connectors - the Han® Ex series - that meet the safety requirements for ignition protection in Ex zones 1 and 2. The use of such connectors, featuring innovative termination techniques supporting unskilled assembly and flexible hood and housing mating solutions, allows end users and installers more installed site flexibility and keeps costs down through time saving in various hazardous application areas including process automation in the petrochemical, chemical and mining sectors.
Condition monitoring
Operators of oil and gas platforms need to continuously monitor their sites’ ambient condition status through parameters such as gas concentration levels, differential pressures and temperatures. Mobile explosion-proof detectors and transmitters allow such measurements to be made at various different key locations on the platform and then be re-positioned as required. The readings from these instruments are switched and recorded via an explosion-proof central controller. These pre-existing detectors and central controller enclosures will typically already have glanded conduit access points. Because of the stringent requirements of explosion-proof equipment, users need to avoid making any modifications to such certified equipment.

In order to save valuable installation time and to maximise location flexibility of such a mobile detection system onto an oil or gas platform installation, Harting offers an exposion-proof connection solution with the compact Han® Ex 4A cable-to-cable connector system, a product that can be retrofitted without compromising the equipment’s Ex certification compliance. Because all detectors are provided with pre-fitted connector cable ends, they are supplied to site fully pre-tested, which ensures fast pluggable installation.

For the links to the central controller enclosure already located on site, cables can be wired through existing glands and conduits, leaving free ends for cable-to-cable connector termination. Harting provides its mating cable-to-cable connector with tool-less quick-lock termination connector inserts, allowing for quick and simple non-specialist wiring on-site installation.

The application of the Han® Ex 4A cable-to-cable connector system allows the connection between the controller and the detectors to be made outside the explosion-proof enclosure, hence ensuring that there is no modification done to the enclosure and no need for re-certification of equipment.

Lifting cranes
Another offshore oil and gas platform related application where connectors offer significant benefits over hard-wiring is on mobile heavy lifting cranes, which may need to be frequently removed and re-installed at different locations. While the crane platform and operator cabin are installed in the so called “safe zone”, the boom is operating in the hazardous zone, thus making it mandatory to use ATEX approved components. The boom carries a number of different sensors (for detecting angle and load, for example) and a light bar at its tip; near the cabin various connectors are used at a panel where all the sensors are wired up.

Across the general “Ex” sector, the replacement of defective loads such as low-voltage switchgear, generators or pumps is complex: the power has to be switched off before the defective equipment can be uninstalled and replaced. With a hard-wired installation, all cores would have to be screwed or connected individually. Connectors, on the other hand, reduce downtime and support modern and flexible machine configuration through modularisation in hazardous areas. Harting’s Han® Ex series connectors are available in different tool-less contact wiring termination designs, so that no specialist skilled personnel are needed for initial assembly and replacement of components. Similarly, the installers require no special tools, thereby accelerating the switch-out operation while maintaining all safety functions. Crimp termination is also an option for the volume OEM manufacturing producer.

Meeting protection requirements
Intrinsically safe explosion protection is based on the limitation of the power circulating in intrinsic circuits, permitting electrical devices to be operated safely even in an explosive environment. Han® Ex connectors meet the standards for materials that are permitted to be used in potentially explosive atmospheres (DIN EN 60 079-0). Air clearance and material creepage distances are in accordance with the intrinsically safe circuit requirements for zones 1 and 2. Their blue colour provides easy identification of inherently safe circuits and they ensure protection class IP65 when mated or unmated in conjunction with appropriate lanyard attachable loose covers (plastic for Han® Ex B and powder coated blue zinc die-cast for Han® Ex 3A series).

Safety relays are diagnostics enabled!

The new KFD2-RSH safety relays from Pepperl+Fuchs combine a diagnostic function, line fault transparency, and dual redundancy in a 1oo3 (one out of three) architecture. During each switching operation, the function of the switching contacts is automatically checked.

This drastically reduces the effort required for proof testing. Thanks to line fault transparency, the entire signal circuit can be monitored for line faults without the need for additional wiring. The relays are immune to test pulses and are therefore compatible with digital output cards for all common control panels.

The 1oo3 architecture with dual redundant switching contacts is at the core of the new modules. For DTS (de-energized-to-safe) applications, there are three serial contacts. For ETS (energized-to-safe) signal circuits, there are two groups of three contacts each, arranged in parallel. The safety function is ensured, even if up to two contacts in a group fail.
The integrated diagnostics function moves the three contacts successively with a time delay during each switching operation. In ETS applications, all three relays of both contact groups are initially closed with three consecutive switching events. During the delay period, the device checks whether this contact closes the circuit and detects any faulty circuits.

DTS device diagnosis takes place during the restart process. Initially, two relay contacts are closed simultaneously, then the third contact is closed after a time delay. The idea is that there is no current flowing before the third contact closes, otherwise this relay is defective because it no longer disconnects the circuit. Another relay is checked during every switching cycle.

After switching three times, the relay module is fully tested once without any additional effort. The diagnostics results are provided:
• via the LED on the module
• as a collective error message on the power feed module
• by evaluating the test pulses from the control panel
• on the additional relay output

The KFD2-RSH safety relays provide comprehensive line fault transparency. As a result, short circuits and lead breakages can also be detected on the field side through the control system's digital output card (DO card) and assigned to a specific signal circuit. No additional wiring is required.

DO cards on control panels often offer built-in diagnostic functions. The module input effectively filters the test pulses coming from the DO card. This prevents an unintentional switching of the field device as a result of a diagnosis measure or the unintentional display of a line fault in the control panel.

The single-channel devices are certified in accordance with the ATEX/IECEx Zone 2 and UL standards and are suitable for DTS and ETS applications up to IEC61508 SIL 3. The DTS modules are also suitable for applications up to EN ISO 13849 PL e.
