Industrial grade vibration transducers with the high temperature 10pC/g version rating up to 400ºC. Signal output is floating,
via 2 pole hermetic connector, thus minimizing common mode
interference. Ingress of contaminants into the transducer and/or
connector will degrade data. Transducers and cables can be supplied
proof pressure tested to 80bar, individually and as
Pressure tested assemblies may be disconnected for ease of installation,
subsequently replacing the sealing ring between the connector shells. The
HT is proof to 400ºC Exposure and is therefore suitable for gas turbine bearing
vibration monitoring, with the proviso that a low pass inline filter may be
needed to minimize blade passing frequency modulation, which gives rise to spurious
phantom low frequency signal generation.
High temperature operation of the HT may be subject to degradation due to
increased pyro-electric charge generation, together with significant fall in
insulation resistance. Instrumentation bandwidth should be constrained to the
minimum needed for measurement integrity. A/107’s comprise isolated welded
hermetic case. Internal electrical connections are welded. Pressure and thermal
cycle tests are recommended for hostile environment applications
All DJB Accelerometers are calibrated on site prior to despatch, and are accompanied by a calibration chart with temperature and frequency responses listed.
Periodic calibration can be carried out with our VC-01 Handheld Calibrator whilst we also offer a full calibration service including cross axis checks to aid accuracy of data.
We are able to provide this service for all makes of accelerometer with a full report given for each device. Please contact us with an enquiry
