High output Konic Shear® IEPE vibration transducer utilizing DJB’s unique and technically superior Konic Shear design of piezoelectric ceramic sensor. Available with a sensitivity up to 3V/g which offers a measurement range of 1.6g the A/121 can be used to measure low level building vibration as well as other applications where minimal vibration is present.  Using a wide range of IEPE signal conditioning levels the A/121 range can interface directly to a wide range of commercially available vibration spectrum analysers and data acquisition systems as well as in our own CV9 signal conditioners which offer a range of normalizing and amplification options.  Version A/121/VI incorporates a three pole band pass filter for noise rejection with a case isolated signal outlet for common mode interference rejection.


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
