Bently Nevada 3500/72M Reciprocating Rod Position Monitor

Overview

The Bently Nevada 3500/72M Reciprocating Rod Position Monitor is an advanced device designed for continuous monitoring of reciprocating compressors. It processes signals from proximity transducers and provides both dynamic and static position measurements. The module compares these measurements with user-programmable alarms, enabling proactive maintenance and enhanced operational safety.

By configuring the 3500/72M via the 3500 Rack Configuration Software, users can easily set alert and danger setpoints for each measured value. This allows real-time monitoring and control, ensuring that any changes in machine behavior are promptly detected.

Key Features

• Dynamic and Static Monitoring: Monitors reciprocating compressors using input from proximity transducers for both dynamic and static position measurements.
• User-Configurable Alarms: Allows customization of alert setpoints for each measured value, ensuring proactive alerts for maintenance.
• Continuous Protection: Continuously compares monitored parameters to preset alarms, triggering relays when required.
• Reliable Machine Condition Monitoring: Provides essential monitoring to assess the health and performance of reciprocating compressor machinery.
