Description
The Bently Nevada 3500/45 140072-04 Position Monitor is a four-channel module designed for continuous monitoring of shaft position and axial displacement in critical rotating machinery. As a core component of the Bently Nevada 3500 rack system, this module interfaces with proximity probes and Proximitor sensors to provide precise, real-time position data. It is essential for protecting rotating equipment against excessive axial movement, providing programmable alarm and trip functions to prevent mechanical failure.
Features
- Four independent monitoring channels for comprehensive shaft position and thrust measurement.
- Compatible with standard Bently Nevada proximity probe and Proximitor sensor systems.
- Programmable Alert and Danger setpoints for customized machinery protection.
- Integrated rack-based design for seamless communication with 3500 relay and communication modules.
- Continuous self-diagnostics to ensure system integrity and sensor health.
Applications
- Steam and gas turbines.
- Centrifugal and axial compressors.
- Large pumps and motors.
- Critical rotating assets requiring axial displacement monitoring.
