Overview

The Bently Nevada 1034549-20 Proximitor Input Module is designed to interface with eddy-current proximity probes for accurate non-contact measurement of shaft vibration and position. It converts probe signals into proportional voltages with high-precision conditioning—amplification, filtering, linearization, and digitization—ensuring trustworthy data in demanding rotating-machinery environments.

This module enables real-time diagnostics and integrates seamlessly with FieldMonitor 1701/15 and Bently Nevada 3500 protection systems. In critical assets such as steam and gas turbines, it supports early detection of faults including imbalance, misalignment, and thrust bearing degradation, helping prevent costly failures and downtime.
