Bently Nevada 3500/64M 176449‑05 Dynamic Pressure Monitor Module

The Bently Nevada 3500/64M 176449‑05 is a four‑channel dynamic pressure monitor module belonging to the 3500 machinery protection rack system. It receives signals from dynamic pressure transducers and continuously measures pressure pulsations, detecting combustion oscillation and unstable pressure fluctuations of rotating and reciprocating machinery.

This single‑slot monitoring board features high‑frequency sampling and built‑in digital filtering functions. It supports user‑configurable alarm thresholds and sends measurement data and fault alarms to the rack controller. It is widely stocked as original spare parts for gas turbine and compressor protection system maintenance, retrofitting and field replacement work.
