Product Overview

• PN: 135137-01
• Brand: Bently Nevada
• Series: 3500 Machinery Protection System
• Type: 3500/45 Position I/O Module

• Function: 4-channel position monitoring module with built-in terminals, receiving signals from proximity probes, LVDTs and rotary position sensors. It measures axial thrust, differential expansion, casing expansion and valve position of turbines and compressors, triggers two-stage alarms when parameters exceed limits and uploads real-time data to upper monitoring system.
