Overview

The Bently Nevada Dual Galvanic Isolator (Models: 170190-01, 1034549-40, 141380-01) is a specialized module designed to provide electrical isolation between monitoring systems and field devices. It ensures safe and reliable signal transmission by preventing ground loops, electrical noise, and interference, which are common challenges in industrial environments.

This isolator is widely used in power generation, oil and gas, petrochemical, and heavy manufacturing industries, where machinery protection systems require stable and interference-free sensor signals. By incorporating galvanic isolation, the module enhances system safety and ensures compliance with API 670 standards.

Technical Data

Typical Applications

• Turbine monitoring systems in power plants, isolating vibration and proximity signals to prevent interference.

• Compressor and pump monitoring in petrochemical facilities, ensuring safe and reliable sensor connectivity.

• Oil and gas refineries, where galvanic isolation protects monitoring systems in hazardous zones.

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

For instance, in a gas turbine installation, the Dual Galvanic Isolator ensures that proximity probes and vibration sensors transmit signals safely, eliminating ground loop issues and protecting monitoring equipment.
