Epro ZW0502/1217/0211+PR6423/005-0F2 Shaft Vibration Monitoring System

Product Overview

The A9360/08-09-00 is an industrial eddy current transmitter developed by Epro (Emerson), intended for precise monitoring of shaft vibration and displacement in rotating equipment. It combines measurement flexibility with a compact, loop-powered design, making it suitable for direct integration into control and protection systems.

This module is widely applied in demanding sectors such as power generation, petrochemical processing, and marine systems where measurement stability and environmental resistance are essential.

Measurement Functionality

The transmitter supports two selectable operating modes, allowing it to measure either vibration or shaft position. Mode selection is achieved via internal configuration, enabling adaptation to different monitoring requirements without changing hardware.

It processes proximity probe signals and outputs a proportional 4–20 mA signal, ensuring compatibility with standard PLC and DCS analog input systems.
