Description

The 3500/70M 176449-09 Recip Impulse Velocity Monitor is a 4-channel module designed for monitoring reciprocating compressor crankcase and crosshead vibration. Each 3500/70M 176449-09 channel accepts 1–4 proximity probe signals, with input impedance of 10 kΩ for acceleration and >1 MΩ for velocity. The monitor conditions signals to generate impulse acceleration (0.51–11.72 mV/(m/s²)), Acceleration 2, reciprocal velocity (3.54–22.64 mV/(mm/s)), and low-frequency reciprocal velocity. Configurable alert (1–60 s) and danger (0.1–60 s) setpoints allow continuous protection by triggering alarms when monitored parameters exceed set thresholds. The 3500/70M 176449-09 provides proportional recorder outputs (+4 to +20 mA) for each channel, operates at 7.7 W nominal power, fits 1 front and 1 rear full-height rack slot, and delivers update rates below 100 ms for fast automation integration in compressor monitoring systems.
