SV 85 General Purpose Vibration Accelerometer

The SV 85 is a ICP® based TRI-AXIAL ACCELEROMETER designed for general purpose vibration measurements with the SVAN 958A four-channel analyser. The HERMETIC SEALED tri-axial industrial piezoelectric accelerometer is suitable to monitor the vibration in harsh industrial environment. The signal ground is ISOLATED from the mounting surface and outer case to prevent ground loops.



Piezoelectic accelerometer dedicated to building/ground structure vibration measurements
Compatible with SVAN 958A and SV 106
Hermetically sealed
