BENTLY NEVADA 86517-01-01-01-01 – Accelerometer Interface Module

Product Description

BENTLY NEVADA 86517-01-01-01-01 belongs to the 86517 series Accelerometer Interface Module, product of Bently Nevada (Baker Hughes). It is designed for signal conditioning of piezoelectric accelerometers. The module receives charge signal from piezoelectric accelerometer probes, performs charge amplification, filtering and integration, and outputs two buffered voltage signals for acceleration and vibration velocity. The signals can be fed into TSI systems, data acquisition cards and vibration analyzers for casing vibration monitoring of rolling bearing machinery. It supports long cable transmission with signal buffering and sensor fault detection, serving as a spare signal conditioning component for rotating machinery condition monitoring systems.
