• Isolated Output • Hermetic, integral hardline cable
Miniature, rugged, industrial grade accelerometer with integral hardline cable, suitable for long term vibration monitoring in adverse environments.
These transducers are hermetic and are proof up to 100bar fluid pressure @ 20°C. Isolated signal minimises ground loop interference, however the 2 core cable termination option, being unguarded viz à viz spurious ground loop induced voltage, may need a differential charge amplifier interface. The alternative triaxial cable guards signal transmission external to the accelerometer. Choice of cable is somewhat subjective and involves physical and cost tradeoffs.
High temperature operation (A/53/F/HT) is accompanied by significant reduction in insulation resistance and by increased low frequency pyro-electric noise content. This may impose a minimum frequency constraint. A/53’s have seen extensive long term service in a variety of hostile environments. We recommend thermal burn-in and proof pressure tests where appropriate. KONIC sensing element, all welded construction, and welded cable termination maximises measurement integrity and reliability.

Calibration
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
