RELIABLE LONG-TERM MONITORING OF GAS TURBINES UP TO 700°C
K
istler has added the world’s first high temperature accelerometer to its
pressure sensor for the monitoring of gas turbines. Both the new accelerometers and pressure sensors are designed for long-term use at up to 700°C and are certified in accordance with the European ATEX guide lines for explosion prevention (Ex-nA and Ex-ia). The piezoelectric accelerometer is not pyroelectric and does not show any moisture-induced stress (popcorn effect) offering manufacturers and operators of gas turbines new options for monitoring the combustion stability. The efficient and secure operation of gas turbines relies upon stable combustion
processes. These have to comply with increasingly strict regulations, including flexible operation on different fuels and minimal emissions. At the same time, there is an associated risk of unstable combustion processes and pressure pulsations. Reliable and continuous monitoring systems are required to monitor and control these combustion processes.

NEW: ATEX CERTIFICATION OF OUR EDDY- CURRENT TACHOMETER FAMILY
of eddy current tachometers including an optional gearbox, has now been approved according to Annex II of the Potentially Explosive Atmospheres Directive 2014/34/EU for all EU countries and the UK. The project was initiated by
A
market requests of potential customers requiring an intrinsically safe tachometer for special applications. And as the portfolio is quite extensive, we decided to have them all certified. After successful testing and modified redocumentation the product range was
certified, including the optional gearboxes, i.e. 12 different models in 4 different product type categories. These mechanical tachometers are used in various industries including refuelling of aircraft, paint production as well as paper and pulp production.

PORTABLE CALIBRATOR MEASURES PRESSURES UP TO 10,000 BAR
W
ith the CPH7000 portable process calibrator, high-pressure measuring
instruments can now also be tested in the field: This multifunction instrument is the first hand-held from WIKA that records measured values of up to 10,000 bar. For such measuring tasks, the portable calibrator uses the WIKA CPT7000 high- pressure sensor as an external reference. Its rupture-proof, thin-film cell is not
welded. It is inserted tightly into a tapered pressure channel and is thus also insensitive to dynamic pressure profiles. Through the combination with this sensor, the already broad range of applications for the CPH7000 is expanded even further. The calibrator is a portable multifunction instrument with an integrated electrical module, a hand pump to generate test pressures up to 25 bar and a high-performance data logger.

ANOTHER STEP IN INNOVATION H

generation CCD100 and CCD104. An evolution of the popular mark two models, they can each power, read and control almost any mass flow meter, controller, pressure transducer or capacitance manometer on the market. The most obvious development is the new screen. The mark two's LCD display (itself
improved from the mark one's LED) has been replaced with an OLED colour display. This strong and clear screen again improves visibility in bright test environments. The CCD100 mark three is lighter and more compact than its predecessor, allowing for use in tighter spaces and requiring less room on a busy workbench. However, it still retains its 1/8 DIN cut out size.

museums, galleries and storerooms to be made easily, thereby ensuring artefacts are kept in a suitably maintained environment. Energy costs can be reduced where energy usage is excessive. The HP32 handheld has an interchangeable probe input for all Rotronic HC2-series probes, full logging & spot-value recording functions and much more. As well as temperature and humidity values, two other moisture parameters such as dew point and g/kg moisture for example can be displayed on the LC screen simultaneously. The handheld replaces the Rotronic HP22 model.
R Instrumentation October 2018
OTRONIC has introduced the HP32 temperature and humidity measurement handheld. This precision instrument enables spot-checks of temperature and humidity levels in
The HP32 handheld is supplied with HW4-LITE version PC
software, a micro USB data cable for PC connection and battery charging, and a soft protective case. A technical datasheet is available. The HP32 is now additionally available in a SET that includes a standard HC2A-S probe (HP32-S-SET); also available with the option of a probe, extension cable, calibration device, pack of humidity standards and protective case with cut-outs (HP32-SET).
