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.
Applications
-
Turbomachinery thrust monitoring
-
Valve stem position tracking
-
Case and shaft thermal expansion detection
-
Differential and ramp differential expansion monitoring
-
Complementary and custom expansion monitoring in high-precision systems
Key Advantages
-
Accepts multiple transducer types: Proximitor, RPT, DC LVDT
-
External termination version (02) for modular installations
-
支持s a wide range / position measurement functions
-
Channel-pair configuration enables simultaneous multi-function use
-
Accurate signal conditioning with user-defined alarm thresholds
-
Fully compatible with 3500 Rack Configuration S/tware
