Overview

The Bently Nevada PWA 79482-01 Dual Thrust Monitor is a specialized monitoring module designed to provide continuous protection for critical rotating machinery. It measures axial shaft position (thrust) using dual-channel inputs, ensuring redundancy and accuracy in detecting thrust bearing wear, misalignment, or excessive axial movement.

This monitor is part of Bently Nevada’s trusted 3300/3500 Series Machinery Protection Systems, engineered to meet API 670 standards. Its dual-channel design enhances reliability by providing independent thrust measurements, making it a preferred choice in industries where machinery uptime and safety are paramount.

Technical Data

Typical Applications

• Steam and gas turbines in power plants, monitoring thrust bearing wear and axial shaft movement.

• Compressors and pumps in petrochemical facilities, ensuring safe operation of critical rotating equipment.

• Oil and gas refineries, where thrust monitoring prevents catastrophic failures.

• Heavy manufacturing plants, supporting condition monitoring for motors, gearboxes, and production machinery.

For example, in a gas turbine installation, the PWA 79482-01 Dual Thrust Monitor provides redundant thrust measurements, enabling operators to detect abnormal axial movement early and prevent costly downtime.
