Product Overview

• PN: 3500/40M, Part No: 140734-01
• Brand: Bently Nevada
• Series: 3500 Machinery Protection System
• Type: Proximitor Monitor Module

• Function: This 4-channel monitor works with eddy current proximity probes to measure radial vibration, axial thrust displacement, eccentricity and differential expansion of turbines, compressors and generators. It sets two-stage alarm thresholds for equipment fault protection and transmits real-time operating data to the upper monitoring platform.
