Bently Nevada 3300/20-13-03-01-00-00 Axial Position Dual Thrust Monitor

Product Overview

The 3300/20-13-03-01-00-00 is a precision Dual Thrust Position Monitor belonging to the Bently Nevada 3300 Series machinery protection system. This module is specifically engineered for the continuous tracking of a rotating shaft's axial (thrust) position. By interfacing with Bently Nevada proximity transducer systems—such as the 3300 XL 8 mm probes—the 3300/20 provides critical data to prevent catastrophic machinery failure caused by excessive axial movement. This specific configuration features a layered protection strategy with three integrated relays and a flexible recorder output, making it a cornerstone for safety-critical monitoring in turbines, compressors, and high-speed pumps.

Core Performance Features

• Dual-Channel Redundancy: The module monitors two independent channels, allowing for voting logic or redundant probe placement to eliminate false trips while ensuring absolute protection.

• Layered Alarm Protection: Equipped with three physical relays, the module provides a multi-stage safety response: one Alert relay for early warning and two Danger relays for emergency shutdown triggers.

• Flexible Data Acquisition: Integrated recorder outputs can be configured by the user to provide either proportional voltage or current signals, facilitating easy connection to external PLC, DCS, or SCADA systems.

• Vibration and EMI Resistance: Built with a rugged aluminum faceplate and high-quality internal shielding, the monitor maintains accuracy in high-vibration and electrically noisy industrial environments.

• Continuous Self-Diagnostics: The monitor constantly performs internal self-tests to ensure the integrity of the proximity probe circuit and the module's own logic processing.
