SV 80 General Purpose Accelerometer 100 mV/g The SV 80 accelerometer is an ideal choice for walk-around vibrations measurement in the rugged environments of industrial machinery monitoring, such as pumps, motors or fans.
It uses the industry standard ®ICP 2-wire voltage transmission technique with a 4 mA standard constant current supply. Signal ground is isolated from the mounting surface to prevent ground loops. Annular shear mode design prevents from thermal transient and from spurious signal from high transverse vibrations. Low noise electronic and a temperature compensated design gives the accurate result over the complete temperature range.
