PRODUCT INFORMATION
Product Overview
The Bently Nevada 3500/45 Position Monitor is a 3500 series four-channel module for continuous machinery protection. It accepts input from proximity transducers, rotary position transducers, DC LVDTs, AC LVDTs, and rotary potentiometers. The instrument conditions incoming sensor signals continuously. It compares conditioned values directly against user-programmable alarm setpoints.
Channels operate in programmed pairs to perform up to two distinct measurement functions simultaneously. Configurable modes include axial thrust position, differential expansion, case expansion, and valve position. The monitor installs into one full-height front rack slot. Matching rear I/O modules provide field signal wiring connections.
