Camogie team qualifies for National tournament!

For the first time in five years the young women of Celbridge GAA club (IRL) have qualified for the Féile na nGael All Ireland Tournament, and Mitsubishi Electric are supporting them all the way.
The Féile na nGael All Ireland Tournament is an annual GAA Tournament running since 1971 which encompasses all 32 counties in Ireland. The tournament consists of the Gaelic sports of hurling, camogie and handball and is organised by the Gaelic Athletic Association (GAA).

This year the annual tournament will be held in Ulster with over 152 clubs and 3,000 players participating. The tournament will be held on the weekend of 19th – 21st June across the nine Ulster counties and County Louth where representatives from Ireland and overseas will be hosted.

The young women of Celbridge Camogie will be representing County Kildare in the U14 Camogie tournament. “This is the first time in 5 years that Celbridge Camogie have qualified for this National Tournament and we are delighted that Mitsubishi Electric are helping them get there,” said Seán Ó Riain, Camogie Coach, Celbridge GAA Club.

“Mitsubishi Electric recognise the role sport plays in the personal, social and cultural development of young people in communities. It helps teach people from a young age important skills such as team work and leadership and we are proud to be able to support the Celbridge girls in any way we can,” Ciarán Moody, General Manager, Mitsubishi Electric Ireland.

• So what is Camogie. Here's the story!

Silica monitoring supports power station efficiency.

Silica deposition on turbine blades can cause defects and an imbalance in the blades, which in turn causes vibration and could even result in failure. Silica deposition in boiler tubes is also to be avoided because it causes a loss of thermal efficiency, thereby reducing the efficiency of the whole plant. So, it is VERY important to keep silica levels very low and to monitor accordingly. This case study provides further information on why this is important and how a successful monitoring programme has now been achieved at this power station in England.
West Burton B CCGT (pictured) is a Combined Cycle Gas Turbine power station near Nottingham in the UK. It has three open-cycle gas turbines capable of generating enough electricity for approximately 1.5 million British homes. In common with all combustion based power stations, the CCGT has a requirement to monitor silica levels in the Plant’s water and steam processes. Seán Todd, the Plant’s Control & Instrumentation (C&I) Team Leader, says: “Boiler chemistry is one of the major challenges facing power plant managers, and the monitoring systems that were originally installed at this plant met the required specification but failed to deliver the accuracy and reliability that we need.

“At the Start of February 2014, we replaced the monitors with HACH 5500sc Silica Analysers and have been absolutely delighted with the results; over the last ten months, the new monitors have proved to be extremely accurate and reliable, requiring very little maintenance.”


The importance of Silica
Making up a large percentage of the earth’s solid crust, silicon (Si) is second only to oxygen in natural abundance. Silicon is present in small concentrations in all natural water supplies, usually as dissolved silica or as small suspended silicate particles (colloidal silica). Silicon dioxide, also known as silica, is a chemical compound that is an oxide of silicon with the chemical formula SiO2. Silica is highly soluble in steam, so if sufficient quantities are present, it may deposit as a glass-like substance on the surfaces of turbine blades and boiler tubes.

Silica deposition on turbine blades can cause pitting and other defects, however, it is also likely to cause an imbalance in the blades, which in turn causes vibration and could even result in failure due to the fine tolerances between turbine blades and outer casings. Turbines cost tens of millions so effective inspection and maintenance is a high priority. Silica deposition in boiler tubes is also to be avoided because it causes a loss of thermal efficiency, thereby reducing the efficiency of the whole plant.
Prior to the installation of the HACH 5500sc Silica Analysers, the unreliability of the original monitors meant that manual samples had to be taken twice daily from multiple points. Some of these samples were tested in a site laboratory, but others had to be sent to a sister laboratory approximately 50 miles away. This incurred excessive costs and delays. Furthermore, the original monitors required frequent recalibration, causing a heavy maintenance requirement and resulting in excessive use of reagents.

Monitoring systems
Silica concentration data is required to demonstrate compliance with the required levels for boiler feedwater and saturated steam. However, the data is also necessary for operational purposes; to control pH in the boilers with ammonia dosing for example. In addition, the data is required for insurance purposes.

In order to avoid silica deposition, high levels of treatment are necessary to produce almost totally demineralised water. CCGT draws its water supply from the River Trent and a variety of treatment processes are necessary before the water is pure enough for use. These processes include sedimentation, filtration, flocculation and ion exchange. The silica analysers draw treated water samples from the plant to ensure that levels are within acceptable limits. Online samples are also drawn from strategically located points in the plant to ensure that silica levels remain at acceptable concentrations throughout the process.

Online monitoring is conducted in two locations; in the Water Treatment Plant for monitoring the efficiency of the ion-exchange plant and in the ‘boiler analyser house’ which contains two Hach 5500sc silica analysers, a Hach 9240 sodium analyser, two HACH ORBISPHERE K1100 LDO optical dissolved oxygen probes, five pH probes and twenty one conductivity probes. Continuous water samples of steam and blowdown steam are delivered to the analyser house by a network of sample tubes from around the plant.

The new HACH ORBISPHERE K1100 LDO (luminescent dissolved oxygen) probes have also helped to minimise the maintenance requirement of the monitoring systems. Employing an optical measurement technology, these probes only require calibration every 6 – 12 months and an optical spot change every few years. This is in stark contrast with the older electrochemical membrane-covered DO sensors that actually consumed oxygen as part of the measurement process and tended to drift, which meant that they required frequent recalibration. A portable version of the ORBISPHERE 3100 LDO is also employed by the site’s boiler chemist, enabling them to conduct rapid measurements at any point on the plant.

The HACH 5500sc Silica Analysers take measurements from each sample stream every 15 minutes, which provides Sean Todd and his team with almost live data on performance and enables them to take appropriate action before alarm levels are reached.

The 5500sc measures silica by reacting samples with molybdate ions under acidic conditions to form silicomolybdic acid complexes. The addition of citric acid destroys the phosphate complexes, and amino acid reagent is then added to reduce the yellow silicomolybdic acid to an intense blue colour, which is proportional to the silica concentration, and measured optically at 815 nm. Typically, just two litres of reagent are required for the analyser to perform unattended for up to 90 days.

An important innovation in the 5500sc analysers, which has dramatically improved accuracy and reliability whilst reducing costs, is the industry's only pressurised reagent delivery system which eliminates the frequent maintenance associated with pumps. “The cabinet inside the analyser is pressurised, and this is released when the door is opened,” says C&I Technician Nick Craddock . “It is then a simple and clean procedure to swap the bottles.”

The analysers autocalibrate once per week, using an internal 500 ppb Silica standard, and Nick Craddock says: “The reading is normally 501 or 502 ppb so these new monitors are incredibly accurate, and much lower cost to run – we change the reagents every 90 days, whereas we used to have to change them after about 30 days. In addition to silica measurements, the analysers also provide a continuous update on their ‘health status’, which enables preventative maintenance and helps avoid downtime.”

Instrument health status is managed by the PROGNOSYS software package. The HACH 5500sc silica analysers operate and configure the software, displaying horizontal bars as a measurement value indicator and as a service indicator for the remaining time until the next maintenance task - green, yellow and red indicators show the status of each sensor. The service messages supply information on maintenance tasks that the user must complete (e.g., to clean the sensor or replace the reagents). All service messages have a countdown period with sufficient time to contact a service technician or to order a replacement part.

Following the installation of the new monitors, HACH LANGE was awarded a service contract which will involve biannual visits to check and refurbish the monitoring systems.

Conclusions
Summarising, Sean Todd says: “As a CCGT power station we have an extra focus on accuracy because of the finer tolerances that feature in this plant, so there is a greater emphasis on the performance of our monitoring systems, and with a small C&I team, we are constantly seeking new ways to reduce maintenance requirements and improve efficiency.

“Boiler chemistry is an important issue for us, so the development of accurate, reliable silica monitors has been an enormous benefit. The operators of other power stations are of course very interested in our success, and we are very happy to share our experiences with them.”

A Practical Guide to Improving Temperature Measurement Accuracy! @MII_Worldwide #PAuto

For many temperature applications, getting a high level of accuracy is vital. A new white paper from Moore Industries highlights how plant and site engineers can ensure the most accurate temperature measurement for critical applications. 

Click image to download!
Available for download from the Moore Industries website“A Practical Guide to Improving Temperature Measurement Accuracy” details steps that can also help end users improve the stability of their measurements and reduce calibration costs.

The paper shows how to select the best sensor for a particular application and ways to improve the accuracy of the sensor you choose. In particular, it details the reasons why 4-wire RTD sensors are almost always the best choice for high-accuracy temperature applications. Using 4-wire RTD sensors eliminates the errors caused by a copper lead wire. The paper also explains the relationship between classes of sensors (such as Standard and Premium Grade thermocouples and Class A RTDs) and their error rates.

Along with learning how to select sensors, the paper also covers how to reduce errors caused by plant noise, using bath calibration to minimize RTD measurement errors and the relationship between remote I/O and temperature accuracy.

Tiny wireless switches!

The outstanding feature of .steute's new RF 13 wireless switchgear series is immediately obvious: they are extremely compact in their design. In figures: with housing dimensions of just 49 x 40 x 21 mm, they are the smallest self-sufficient wireless switches for industrial applications currently on the market.

And – what cannot be seen – they are also characterised by a switching performance to match that of any microswitch.

They can be integrated just as easily and flexibly into steute Wireless systems as our larger series. Like them, the RF 13 is also equipped with an electrodynamic energy generator. This miniaturised generator converts the kinetic energy produced by actuating the switch into electrical energy, which is then used to transmit the signal. This means that the switch is able to work self-sufficiently. It needs neither batteries nor an external power supply, i.e. no cables.

Another thing which makes it so flexible to incorporate is the fact that it is compatible with all actuators in the .steute range. Finally, its miniaturised design makes the RF 13 perfectly suited to applications for wireless switches in places where they really make sense because space is so tight – e.g. for position monitoring in or on moving systems such as tools, feeders and handling systems.

Fascinating! Steering wheel that keeps you awake!

The innovative SensoFoil sensing technology now can measure sensitivity in addition to position according to a release from Hoffmann-Krippner Inc., in cooperation with Guttersberg Consulting. 
By using enhanced SensoFoil to measure pressure, car and vehicle manufacturers can add an extra level of safety to their steering wheels. During normal driving, the operator is constantly moving their hands on the steering wheel, changing pressure as the fingers grip the wheel. However, by using Hoffmann-Krippner’s SensoFoil inside the steering wheel, the vehicle can now sense if the driver’s hands are now longer moving  – if the operator has fallen asleep with their hands on the wheel or if their hands are no longer on the wheel. This can trigger the correct safety protocol to either wake up the driver or to implement corrective measures.
(See fascinating video below!)

Traffic experts claim that about 25% of all accidents are caused by extreme fatigue while driving. This makes nodding-off, also referred to as “micro-sleep“, in combination with heart attacks, as  the leading cause of accidents, exceeding the number of accidents caused by alcohol and drugs.

Once alerted by the Smart Steering Wheel, the car can try to wake the driver or take over control and steer the vehicle to a safe stop along the road. In case of medical emergency, the car could even drive itself to the closest medical emergency center while sending out an alert to the appropriate authorities.

The sensor can also be programmed for pressure in certain locations. This can be used in a vehicle to control various location, emergency, entertainment or communication systems. This same feature can be used in game controllers, aircraft, etc., as an economical way to add additional programmable capabilities to a controller or joystick device without the need for extra buttons or dials.

“Pressure Sensing SensoFoil cost effectively provides extra features and capabilities to a diverse range of products,” says Jens Kautzor, CEO of Hoffman + Krippner, Inc. “In addition, this sensing technology requires very little external energy since power consumption is very low. The sensor system is insensitive to electromagnetic radiation and therefore ideal for the automotive, aerospace and medical sectors.”

Voltage proving tool.

Fluke has introduced a new battery powered electronic voltage source that sources both AC and DC voltages for test tool verification.

The new Fluke PRV240 Voltage Proving Unit can be used to test both high and low impedance digital multimeters, clamp meters and Two Pole Testers. It provides a stable, fixed output voltage to properly assess correct operation of many types of electrical tester, clamp meters and multimeters. Verification of a test tool is recommended by both GS38 and NFPA 70E before any live measurements are made.

The Fluke PRV240 Proving Unit is an easy-to-use product for electricians, commercial or industrial technicians, HVAC technicians or anyone working remotely who needs access to a voltage source to verify their tool is working correctly. The PRV240 is the ideal solution for electricians, environmental health and safety managers, plant safety officers (for example at oil & gas and chemical processing plants), facilities managers and other managers concerned with electrical safety and compliance.

The PRV240 comes with a TPAK magnetic hanging strap for convenient operation. It has re-chargeable internal battery power sufficient to perform 5000 verification tests.
