2.1.2 SV 84
– Building / Ground Vibration Accelerometer
SV 84
is a low-noise, hermetically sealed triaxial piezoelectric
accelerometer designed to monitor building and ground vibrations
with the SVAN 958A instrument.
A hermetically sealed glass connector protects the SV 84 from
harmful dust and moisture enabling the outdoor use without
additional enclosures.
The signal ground is insulated from the mounting surface and outer
case to prevent ground loops.
The SV 84 is a part of the SV 207B set that includes also metal
mounting adapter.
Note: See SA 84 Technical Specification on www.svantek.com.
Note: Correct connection of the accelerometer is not signalled by the controller, therefore it is
recommended to perform test measurements each time the station is turned on.
