ProLine P50000 from Knick:
Innovative High-Voltage Transducers for Railway Applications
ransducers of the new ProLine P50000 series from Knick Elektronische Messgeräte were specially developed for voltage and current measurement in main and auxiliary power circuits of locomotives and multiple units. They are used, for example, for short circuit detection as well as for monitoring of traction motors and inverters, auxiliary inverters and accumulator batteries. The devices comply with all applicable railway standards and thus meet the high demands of fire protection (HL3 according to EN 45545-2 (2016)), electrical safety, mechanical robustness as well as insensitivity to extreme environmental conditions and electromagnetic interferences. Knick offers a 5-year warranty on these high- precision and long-term stable transducers.

from -60 °C to +60 °C. The devices manufactured from 1.4571 stainless steel and PTFE provide a IP68/IP69K protection rating. Designed for reliable operation even with frequent temperature variations, they are especially suitable for use in rugged industrial environments. The sensors connect to the IKM 122 Ex amplifier. The first models to be introduced are M12 and M18 type sensors. They are connected via a 2 meter FEP cable.

Complete Range of PCB® Triaxial Accelerometers P
CB® offers three-axis accelerometers for a broad range of multi-axis vibration applications. As well as offering Total Customer Satisfaction (TCS), many models are maintained in stock for quick delivery.
Model 356A45 is a new design of triaxial accelerometer, offering a frequency response of 10kHz with a range of ±50g pk, housed in a 10.2 mm cube and incorporating TEDS as standard. Even smaller is a 6mm, 1 gram cube design, the Model HT356B01 for use up to 180°C.
For transient temperature
environments the 339A32 has a temperature coefficient of just ≤0.02%/°C, ideal for vehicle track testing.
Model 356B18 is a 1000mV/g triax resolving signals down to 0.0005g ideal for monitoring vibration in buildings. For shock applications, the Model 350B50 features a measurement range of 10,000g. Model 3503A1060KG is a triaxial MEMS shock accelerometer featuring a 60,000g range.

market, is exhibiting at the Engineering Design Show at the Wasps Arena in Coventry on 19 and 20 October. Its R&D engineers work with design engineers to produce workable cooling technology, right down to miniaturised format. On Stand D60 it will show both water- and air-cooled products.
“Our technical knowledge, flexibility and ‘can do’ approach has secured us a number of high profile engineering contracts across a wide range of industries,” says Stuart Packer,
Technotrans chills at EDS T
echnotrans, a company which specialises in bespoke chilling solutions for a global
sales manager at technotrans,
Colchester. “We are a global business and we work with companies large and small, across a huge range of applications from security and transport to medical and testing equipment. We can provide water- and air-cooled chillers in various sizes and capacities.”
Airport security, polymer testing
equipment, medical and transport systems are typical of the engineering sectors it has been involved in, mostly from design stage.
Earlier this year technotrans helped a specialist in oil and polymer testing equipment, providing a low voltage Aspen compressor married into an ambient temperature test system for chilling the PSL- Rheotek viscometers manufactured by Poulten Selfe and Lee.
Transport has also proved a popular area for bespoke chilling solutions and technotrans has helped with a turnkey tram system in the Qatar capital Doha and also a small format battery cooler for Vantage Power which converts diesel buses in London into low emission hybrid buses.

New pressure sensors for harsh conditions up to 700°C
he new thermoacoustic pressure sensor from Kistler will be shown for the first time in the UK on Stand D5 at the Sensors & Instrumentation Show 2016. The new sensor uses durable piezoelectric material based on Kistler’s proprietary PiezoStar® KI100 crystal material designed for pulsation pressure measurements at temperatures up to 700°C in the harshest of operating environments. Applications include monitoring of gas turbines, and other turbo machinery,
R&D of continuous
detonation engines, monitoring and control of pressure oscillations in pipes and acoustic thermometry. The three types of sensor; base, non- sparking (Ex-Na) and intrinsically safe (Ex-ia), all with integrated Hardline cables up to 10 metres, make ATEX certified measuring chains simple to construct.
internally isolated and have a high natural frequency >50 kHz. In addition to the standard sensor, a wide range of custom sensitivity and signal output options are available.
