Bently Nevada 3300/20-03-01 Dual Thrust Position Monitor

Overview

The Bently Nevada 3300/20-03-01 Dual Thrust Position Monitor is an advanced solution for detecting thrust bearing failures. It continuously monitors two independent channels, measuring the axial position of the shaft relative to the axial clearance in machinery. This device provides early warning of potential bearing issues, ensuring timely maintenance and preventing catastrophic failures.

Designed for precision, the 3300/20-03-01 uses proximity probes to monitor the position of the thrust collar. This allows for accurate measurement of the collar’s position relative to the thrust bearing clearance. The monitor is an essential component in any predictive maintenance system for rotating equipment, providing reliable data to optimize machine reliability and minimize downtime.

Key Features

• Dual Channel Monitoring: Continuously measures and monitors two independent channels for accurate thrust position measurement.
• Proximity Probe Inputs: Designed for proximity probes that observe the thrust collar directly, ensuring precise readings of axial position relative to bearing clearance.
• User-Programmable Sensitivity: Adjust sensitivity to 200 mV/mil (8 V/mm) or 100 mV/mil (4 V/mm) to match the application.
• Output Options: Choose from +4 to +20 mA, 0 to -10 Vdc, or +1 to +5 Vdc outputs for versatile integration with control systems.
• Short-Circuit Protection: Recorder outputs are short-circuit protected, maintaining reliable operation even in harsh conditions.

Applications

• Thrust Bearing Monitoring: Ideal for continuous monitoring of thrust bearing health in rotating machinery like turbines, compressors, and motors.
• Predictive Maintenance: Enables early detection of thrust bearing issues, facilitating proactive maintenance and minimizing unplanned downtime.
• Machinery Protection: Provides crucial data to protect machinery from excessive axial displacement and potential damage to thrust bearings.
