176449-02 | Bently Nevada 3500/42M Proximitor Seismic Monitor

The Bently Nevada 176449-02 3500/42M Proximitor Seismic Monitor is a four-channel monitoring solution designed to ensure optimal machinery protection. It provides continuous comparison of monitored parameters against user-configured alarm setpoints and communicates critical data for operations and maintenance efficiency.

Key Features

Multi-Parameter Monitoring:
- Supports radial vibration, acceleration, thrust position, velocity, eccentricity, and more.
- Channels are programmable in pairs, allowing dual functionality.
Data Conditioning:
- Processes input from proximity and seismic transducers.
- Provides static values with configurable alert and danger setpoints.
LED Indicators:
- OK LED: Indicates proper operation.
- TX/RX LED: Indicates communication with other modules.
- Bypass LED: Shows bypass mode status.
Buffered Outputs:
- Individual coaxial connectors for each channel, short-circuit protected.
- Shaft Absolute outputs with independent channels and short-circuit protection.
