High output industrial grade vibration transducers.
temperature (A/301/F/HT) 25pC/g version is rated to 400°C signal output is floating,
via 2 pole hermetic connector, thus minimizing common mode
Ingress of contaminants into the transducer and/or connector will degrade
data. Transducer and cables can be supplied proof pressure tested to
80bar, individually and as assemblies. Pressure tested assemblies may be
disconnected for ease of installation, subsequently replacing the sealing ring
between the connector shells. The /HT is proof to 400°C exposure and is
therefore suitable for a gas turbine bearing vibration monitoring with the
provision that a low pass inline filter may be needed to minimize blade passing
frequency modulation, which gives rise to spurious phantom low frequency signal
High temperature operation of the HT may subject to degradation due to increased
pyro-electric charge generation, together with a significant fall in insulation
resistance. Instrumentation bandwidth should be constrained to the minimum
needed measurement integrity. A/301’s comprises isolated Konic Shear sensing
element housed in all welded hermetic case. Internal electrical connections are
Pressure and thermal cycle tests are recommended for hostile environment
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
