Product Description
The Bently Nevada 3500/45-01-00 140734-04 Position Monitor is a 4-channel monitoring module engineered to measure the axial and radial position of rotating machinery components. It interfaces with a wide range of transducers, including Proximity Transducers, Rotary Position Transducers (RPTs), DC and AC LVDTs, and Rotary Potentiometers.
The module performs complex signal conditioning and comparison operations, delivering precise position monitoring and triggering configurable alarms when predefined thresholds are breached. It provides key insights into machine behavior, supporting both protection and predictive maintenance.
Each channel pair can be configured independently using 3500 Rack Configuration Software to monitor:
-
Axial (Thrust) Position
-
Differential Expansion
-
Ramp Differential Expansion (Standard/Non-standard/Dual)
-
Complementary Differential Expansion (CIDE)
-
Case Expansion
-
Valve Position
