Product Overview
The Bently Nevada 3500/42-01-00 is a four-channel monitor module for the Bently Nevada 3500 Machinery Health Protection System. It accepts signals from proximity probes, velocity sensors and accelerometers, processes them into vibration and position measurements, and continuously compares the results with user-configurable alarm setpoints to support machinery protection.
The order code 3500/42-01-00 typically corresponds to the 3500/42M Proximitor/Seismic Monitor, with a common front panel part number of 176449-02 and an associated I/O module of 128229-01 (Displacement/Velocity/Acceleration I/O Module with internal terminals). Each channel can be configured through the 3500 rack configuration software to monitor radial vibration, axial position, differential expansion, eccentricity, REBAM, acceleration, velocity and shaft absolute vibration.
Key Features
- 4-channel configurable monitor
Channels are configured in pairs; channels 1/2 and 3/4 can perform the same or different functions. - Proximitor and seismic inputs
Accepts proximity probes, velocity sensors and accelerometers. - Multi-parameter monitoring
Supports radial vibration, axial position, differential expansion, eccentricity, REBAM, acceleration, velocity and shaft absolute vibration. - Alarm and trip support
Continuously compares monitored parameters with configured alarm and danger setpoints to support machinery protection. - 4–20 mA recording output
Provides per-channel 4–20 mA analog output for integration with DCS, PLC or data acquisition systems. - Front-panel LED indicators
OK, TX/RX and bypass LEDs help operators check module status quickly. - 3500 rack compatible
Designed for the Bently Nevada 3500 series rack system and supports hot-swappable maintenance in a properly configured rack.
Typical Applications
- Steam and gas turbines
- Centrifugal and axial compressors
- Generators and exciters
- Industrial fans and blowers
- Pumps, gearboxes and large motors
- Critical rotating equipment in power, oil & gas, petrochemical and heavy industrial plants
