Bently Nevada 86517-01-01-01-02 Accelerometer Vibration Sensor

The Bently Nevada 86517-01-01-01-02 is an ICP-type piezoelectric accelerometer designed for absolute casing vibration measurement of rotating machinery. It converts mechanical vibration acceleration into standard electrical signals and transmits data to online monitoring systems for continuous equipment condition evaluation.

This compact sensor adopts fully sealed stainless steel housing and built-in signal conditioning circuit. It features wide frequency response and excellent anti-interference performance, suitable for high-temperature, dusty and oily industrial environments. Widely matched with Bently 3500 series monitoring racks for energy and petrochemical plant maintenance and spare parts supply.
