Piezoelectric vibration velocity sensor PZDC Series

rotary machinefor fansfor pump

The PZDC series of vibration transducers are robust sealed instruments providing a process current output of 4-20mA proportional to RMS velocity vibration. The series are designed for applications requiring direct integration to SCADA systems (PLC/DCS) and provide an extremely cost effective solution for measuring overall vibration performance. Available in either a top exit or a side exit hermetically sealed housing, the PZDC 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 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. Application Direct DCS/PLC/BMS integration for Pumps, Fans, Motors and Process Equipment.
