Product Details: Bently Nevada 90225-23-03-05-01-02-02-03-01-02 is a high-performance industrial piezoelectric accelerometer designed for absolute casing vibration measurement on rotating machinery. This Piezo Vibration Transducer utilizes piezoelectric principle to convert mechanical acceleration vibration into electrical signal, suitable for capturing high-frequency vibration caused by bearing wear, gear mesh and mechanical looseness. It adopts fully hermetic stainless steel housing construction, offering reliable protection against oil, moisture, dust and mechanical shock in harsh petrochemical and power plant environments. The multi-segment ordering code defines sensitivity, cable configuration, mounting thread, connector type, temperature rating and hazardous area certification parameters for this unit. The sensor needs rigid mounting on bearing housing or machine casing surface, and the sensitive axis should align with the vibration measurement direction. Poor mounting will lead to signal distortion and loss of high-frequency vibration data. Signal wiring should be routed separately from high voltage power cables to minimize electromagnetic interference. Periodic visual inspection of housing, cable sheath and connector is required during equipment shutdown, and regular calibration is recommended to maintain measurement accuracy. Widely used in power generation, petrochemical and heavy industrial fields, this Casing Vibration Sensor monitors turbines, centrifugal compressors, generators, fans and pumps, supporting predictive maintenance and early mechanical fault identification to avoid unplanned downtime.
