Eddy current probe operates at high
temperatures
Sensonics has developed the PRS05 Senturion Proximity Probe capable of operating at temperatures over 200degC, which are common in applications such as steam and gas turbines.
Designed to be the most robust available, Sensonics range of Senturion Proximity Probes has been extended to include an instrument capable of operating to temperatures of 240degC Used extensively throughout industry to monitor rotating shaft alignment and axial position, particularly on steam and gas turbines, centrifuges and pumps, Sensonics proximity probes provide a range of non-contacting measurement configurations and comply with the API 670 standard

Probes and tranducers win ATEX approval
ATEX approval has been secured for a range of velocity transducers, accelerometers and eddy current probes, for use in the measurement of vibration and non-contact displacement.
Accelerometers approved for more critical usage
Used to monitor machinery vibration, the recertified Sensonics PZS accelerometers can now also be used to monitor gas turbine sets as well as motors, pumps and power turbines.
Vibration transducer catalogue and live demos
Predictive Maintenance specialist Sensonics will be releasing its new 20 page Vibration Transducer Catalogue and displaying other detailed technical literature at the Maintec exhibition (Stand F9).
Available in a selection of body and cable lengths, the PRS05 model from Sensonics offers a 0 to 5mm measurement range in a 12mm tip (M18 body) configuration and operates above the range of standard probes, which can experience excessive drift where temperatures exceed 150degC and typically will be manufactured in materials only suitable for occasional operation up to 200degC.
Temperatures in many applications can rise above this 200degC ceiling for long periods at a time in the locality of the probe; during turbine run up where steam leaks are prevalent, it is key the measurement accuracy is maintained for both thrust and shaft vibration measurements as the turbine thermal characteristics stabilise.
The new PRS05 solution maintains a measurement error of less than 5 percent over the full working temperature range.
Rugged and reliable, the new probe incorporates a glass filled PPS bobbin case rated to 300degC, which is both oil and chemical resistant.
A bobbin expansion chamber and wire strain relief techniques for the cable interface are just two of the design enhancements incorporated to achieve the 240degC rating.
The instrument is supplied with a standard 0.5m of high temperature PTFE cable and is used in conjunction with a coaxial extension cable, supplied as a tuned system with a driver unit Other instruments in the standard Senturion range include straight mount, reverse mount and disc probes offering measurement ranges up to 25mm.
There is an extensive selection of ancillary items additionally supplied by Sensonics; these include brackets, glands and housing for probes and drivers.
The company also provides an advice, installation and commissioning service. Request a free brochure from Sensonics ...
