Sensonics - Model PZV Series -Industrial Velocity Vibration Sensor
The PZV velocity sensor consists of a high performance shear mode piezoelectric ceramic assembly which incorporates an electronic integration function to provide a velocity vibration output. Available in either a top exit or a side exit hermetically sealed housing, the PZV range is suitable for measuring cyclic vibration a wide range of critical rotating machinery, typically mounted on the bearing housing or casing to detect bearing wear and absolute vibration.
The sensor operates on a current-loop principle which permits very long interconnecting cables to be used without loss of measurement accuracy. The standard device sensitivity is 4 mV/mm/s with a vibration measurement range of over 1500 mm/s peak.
The piezo-electric shear mode sensor, amplifier and integrator are contained within an inner metal enclosure, which is electrically and thermally insulated from the outer stainless steel body. The arrangement prevents the opportunity for earth loops eliminating electrical interference, and in addition minimises thermal shocks and base strain effects. The inner enclosure is connected to the 0V of the two wire system and is therefore an effective electrical screen. External connections are available through a wide range of integral cable and connector options.
