The PZS accelerometer consists of a high performance shear mode piezoelectric ceramic assembly available in either a top exit or side exit hermetically sealed housing. The PZS range is suitable for vibration monitoring applications on a wide range of critical rotating machinery and typically mounted on the bearing housing 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 100mV/g with an acceleration measurement range of over 50g which is suitable for most machine monitoring applications. The piezo-electric shear mode sensor and amplifier 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.
