Overview

The Bently Nevada 1034549-40 Dual Galvanic Isolator is designed to ensure safe signal transmission from sensors located in hazardous or electrically noisy environments. It provides complete galvanic isolation between intrinsically safe field transducers—such as proximity probes and vibration sensors—and the FieldMonitor monitoring electronics. This protection eliminates ground loops, reduces noise interference, and prevents fault propagation into critical monitoring equipment.

The module integrates seamlessly with the 1701/06 Isolator Terminal Base, supporting distributed architectures used in vibration and displacement monitoring of rotating machinery. Its rugged construction and global compliance make it suitable for oil and gas, power generation, refining, and chemical processing operations where safety and reliability are mandatory.

For example, in a refinery compressor train with classified zones, the 1034549-40 enables continuous monitoring while maintaining intrinsic safety requirements and system integrity.
