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.
The 3300/20-13-03-01-00-00 offers high-resolution measurement with industrial-grade fail-safe 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.
