General purpose piezoelectric accelerometers well suited to a wide range of vibration analysis and shaker testing applications, particularly those requiring a higher operating temperature.  

Using the unique DJB Konic Shear® piezoelectric ceramic sensing element for superior performance and reduced long term cross axis error. The A/20 range offers a side entry or top entry tapped base model with an all welded titanium construction. In addition the TC version has a hermetically sealed top entry TNC connector. All versions have welded internal connections for a robust sensor suitable for many harsh environments. 

Relative freedom from strain induced error reduces low frequency measurement uncertainty.



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
