Description

The Bently Nevada 3300/20 Axial Position Monitor is a dedicated monitoring module within the 3300 Series machinery protection system. It is engineered to perform precise, continuous measurement of shaft axial displacement, commonly referred to as thrust position. By monitoring the proximity of the shaft to the thrust bearing, this module provides critical data for rotating equipment such as large steam turbines, gas compressors, and centrifugal pumps, enabling early identification of mechanical wear or potential catastrophic failure.

Features

Direct interface with proximity probe transducer systems (Proximitor sensors) for high-accuracy displacement measurement.
Continuous signal processing with real-time comparison against user-defined Alert and Danger setpoints.
Integrated proportional 4–20 mA output for external trending and data integration.
On-board LED status indicators providing instant visual confirmation of OK, Bypass, Alert, and Danger states.
Robust relay output configuration for automated machinery shutdown or alarm annunciation.

Applications

This module is specifically utilized in critical rotating machinery protection schemes. Common applications include monitoring thrust bearing health in industrial turbines, axial movement tracking in heavy-duty compressors, and general axial position oversight in high-speed rotating equipment where precise clearance maintenance is essential for operational safety.

Installation Guidelines

Ensure the 3300 series rack is properly grounded to a clean earth point before inserting the module.
This module is designed for rack-mounting; ensure the backplane connector is clean and free of debris before seating.
Always disconnect power to the rack or follow site-specific lockout/tagout procedures before inserting or removing modules to prevent electrical damage.
Route signal cabling away from high-voltage power lines and sources of electromagnetic interference (EMI) to maintain signal integrity.
Verify that the proximity probe cabling is shielded and that the shield is grounded only at the specified termination point to avoid ground loops.

FAQ

What is the primary function of the 3300/20 monitor?

The 3300/20 monitor tracks the axial position of a machine shaft relative to its thrust bearing. It translates proximity probe signals into readable displacement values and triggers alarms if the movement exceeds safe operational thresholds.

Is this module compatible with standard proximity probes?

Yes, the 01 input option is specifically configured to interface with standard Bently Nevada Proximitor sensors used in 3300 series monitoring systems.

What do the LED indicators represent?

The LEDs provide a quick status check: 'OK' indicates the sensor and module are functioning correctly, 'Bypass' shows the alarm logic is inhibited, while 'Alert' and 'Danger' indicate that the measured shaft displacement has reached or exceeded pre-programmed safety levels.
