SENSING ENGINEERING INNOVATION A/107/F, A/107/F/HT Industrial Piezoelectric Accelerometer 80gm 2 pole connector, lightweight version 100pC/g nom. 300°C max(F) 10pC/g nom. 400°C max(F/HT) Industrial grade vibration transducers high temperature 10pC/g version is rated to 400°C. 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 assemblies. Pressure tested assemblies may be disconnected for ease of installation, subsequently replacing the x-- sealing ring between the connector shells. The HT is proof to 400°C 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. Options: • Temperature calibration to 400°C (/HT) • Proof pressure testing to 80bar • Voltage O/P version: A/1107/VF (100mV/g) DJB Instruments (UK) Ltd Finchley Avenue, Mildenhall, Suffolk IP28 7BG Email sales@djbinstruments.com Web www.djbinstruments.com A UK company with UK-based manufacturing, assembly and calibration in-house.
