Bently Nevada 176449-02 3500 Series Proximitor/Seismic Monitor

Description

Processing vibration and position inputs in industrial machinery requires robust hardware, which the 176449-02 monitor module provides as part of the Bently Nevada 3500/42M monitoring system. This four-channel module accepts input from proximity and seismic transducers, conditions the signals to provide various vibration and position measurements, and compares the conditioned signals against user-programmable alarms.

The primary function of the 176449-02 is to provide continuous machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms, and to provide essential machine health information to both operations and maintenance personnel. Each channel can be configured using the 3500 Rack Configuration Software to perform different monitoring functions depending on the associated transducer type.

Features

• Four channels of continuous, independent machinery monitoring.
• Accepts input from Proximitor probes, accelerometers, and velocity transducers.
• Provides alert and danger alarm setpoints for each configured channel.
• On-board LEDs provide status indication of module health, bypass modes, and alarm states.
• Integrates seamlessly into any standard Bently Nevada 3500 Series rack.

Applications

This module is widely used across heavy industries to monitor rotating machinery assets, including:

• Steam turbines and gas turbines
• Centrifugal and reciprocating compressors
• Electric motors and generators
• Pumps, fans, and blowers

Installation Guidelines

Engineers must follow these core guidelines during system installation:

• Rack Placement: Install the 176449-02 module into any full-height slot in the 3500 rack, except for the power supply and rack interface module slots.
• Shielding: Ensure transducer shield lines are properly terminated at the rack common ground to prevent electromagnetic interference from distorting high-frequency seismic and proximity signals.
• Hot-Swapping: While the 3500 rack supports hot-swapping under designated conditions, safety protocols dictate bypassing active trips prior to removing or inserting any monitor module to avoid accidental machinery shutdowns.
