Products Overview
The 3500/70M 176449-09 Bently Nevada Recip Impulse/Velocity Monitor is a rack-based measurement card built for the Bently Nevada 3500 machinery protection system. The unit provides four independent measurement channels dedicated to reciprocating equipment, capturing impulse and velocity signals from proximity and seismic sensors mounted on reciprocating compressors and engines.
This 3500/70M module processes raw mechanical signals to identify abnormal mechanical impacts and vibration fluctuations unique to reciprocating equipment. It outputs processed data to the host rack and connected DCS or PLC platforms for real-time equipment supervision.

Products Fuction
- Four-Channel Pairing Measurement Function:The 3500/70M 176449-09 supports four separate input channels that can be grouped into paired measurement groups for synchronized impulse and velocity sampling. Each channel accepts standard sensor wiring used across oil and gas compressor stations, and maintains signal isolation between channels to avoid cross-channel interference during long-term continuous monitoring.
- Multi-Mode Reciprocating Signal Processing:Built-in signal filtering algorithms separate normal cyclic pulsation from abnormal impact signals generated by loose valves, piston wear and packing degradation on reciprocating machinery. The card switches between impulse and velocity measurement modes through system configuration software without hardware modification, adapting to different monitoring points on reciprocating equipment frames and cylinders.
- Independent Programmable Alarm & Relay Output:Every channel carries independent threshold settings for warning and critical alarm levels. Once measured values exceed preset limits, the module triggers relay contact signals to drive local alarm lights or unit shutdown protection logic.
- Built-In System Self-Diagnosis Circuit: Continuous internal diagnostics run after power-on and during operation. The 3500/70M 176449-09 detects sensor open circuits, short circuits, signal out-of-range faults and internal board operation errors. Corresponding fault codes transmit to the system display terminal for fast on-site troubleshooting without extra testing equipment.
