Product Overview

• PN: 3500/42M, Part No: 140734-02
• Brand: Bently Nevada
• Series: 3500 Machinery Protection System
• Type: Seismic Proximitor Monitor Module

• Function: This 4-channel module accepts signals from eddy current probes, velocity and acceleration sensors to measure radial vibration, thrust displacement, bearing condition, eccentricity and shaft absolute vibration of turbines, compressors and generators. It provides two-stage alarm protection, 4-20mA analog output and transmits real-time equipment operating data to upper monitoring platforms.
