Bently Nevada|3500/40M 128275-01F|Proximitor® Monitor Module

Bently Nevada 3500/40M 128275-01F Proximitor® Monitor Module

Description
The 3500/40M is a 4-channel monitor module designed for machinery protection, accepting input from Bently Nevada proximity transducers to provide vibration and position measurements with programmable alarms.

Features

• Configurable for Radial Vibration, Thrust Position, Differential Expansion, Eccentricity, or REBAM
• Channels operate in pairs, supporting two functions simultaneously
• Front-panel LEDs for status, communication, and bypass mode
• Buffered transducer outputs with short-circuit protection
