159840-01 Bently Nevada Acceleration Interface Module (86517 Series Dynamic Pressure Sensing Module)

Product Description

159840-01 is an acceleration / dynamic pressure sensing interface module manufactured by Bently Nevada (GE). This compact explosion-proof signal conditioning module is designed for charge-type accelerometer sensors, converting high-impedance charge signals from vibration transducers into standard low-impedance voltage signals for machinery monitoring systems. It features built-in configurable band-pass filters, SIRA intrinsically safe certification for hazardous areas, and terminal block wiring for field sensor connection, widely used as signal front-end for rotating equipment protection and vibration diagnostic systems.
