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.
