Rugged Design with Integral Hardline Cable. Options • Temperature calibration to 260°C (F) • Temperature calibration to 400°C (F/HT) (F/HT-1) • Proof pressure testing to 80bar Applications Aerospace High Temperature Machine Monitoring Condition Monitoring Industrial General Vibration Measurement Bearing analysis Industrial and Aerospace 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. As with all PE accelerometers the 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 assemblies. 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 Calibration All DJB Accelerometers are calibrated on site prior to despatch, and are accompanied by a calibration chart with temperature and frequency responses listed.
