Bently Nevada 3300/20 Dual Thrust Shaft Position Monitor

Product Overview

The Bently Nevada 3300/20-13-03-01-00-00 is a dual-channel thrust position monitor designed for real-time tracking of shaft axial position in high-speed rotating equipment. As part of the 3300 Series, it helps detect early thrust bearing wear, preventing severe machinery damage in turbines, compressors, and industrial motors.

By integrating with 3300/03 rack systems, this module processes input from proximity probes and generates proportional signals. It delivers both Alert and Danger relays per channel, ensuring operators receive immediate warnings of abnormal thrust movement.

Description

The 3300/20-13-03-01-00-00 continuously measures two independent channels of axial shaft position, typically referenced against the thrust collar. This setup ensures precise representation of shaft clearance relative to the thrust bearing. Its buffered outputs support real-time diagnostics, while compliance with API 670 makes it suitable for critical machinery protection applications.

Designed for industrial reliability, it features a rack-mounted form factor, operates within –20°C to +65°C, and supports 7200 Series proximity probes with 8 mm or 14 mm tips.
