The Bently Nevada 3500/45 176449-04 Position Monitor Module is a four-channel position monitoring device designed for the Bently Nevada 3500 Machinery Protection System. It is used to monitor critical machine position parameters including axial thrust position, differential expansion, case expansion, and valve position.
The module accepts input signals from multiple position sensors, including proximity transducers, Rotary Position Transducers (RPTs), DC/AC Linear Variable Differential Transformers (LVDTs), and rotary potentiometers. It conditions the input signals and compares measured values with user-configurable alarm setpoints to provide machinery protection and operational monitoring.

The 3500/45 provides four independent monitoring channels, allowing multiple mechanical position parameters to be monitored within a single rack module.
The module supports various displacement measurement technologies, including eddy-current proximity sensors, RPTs, and LVDTs, providing flexibility for different machine designs.
Users can configure channels for different applications such as thrust position, differential expansion, or valve position monitoring.
The module continuously compares measured values with configured alarm limits and provides Alert and Danger indications for machinery protection.
The 3500/45 works together with other Bently Nevada monitoring, relay, and communication modules to create a complete machinery protection solution.
