Product Overview
The Bently Nevada 3500/45-02-00 Position I/O Module is a 4-channel signal interface designed for critical machinery monitoring. It processes signals from Proximitors, Rotary Position Transducers (RPTs), and DC LVDTs via external terminations. Integrated into the 3500 system, it delivers essential position measurements such as thrust, valve position, case expansion, and differential expansion, ensuring accurate protection and diagnostics for rotating machinery.
