Epro A9360/08-05-00-BSQ Eddy Current Transmitter Sensor

Product Overview

The A9360/08-05-00-BSQ is a compact eddy current transmitter manufactured by Epro (Emerson), intended for continuous measurement of shaft vibration and displacement in rotating machinery. It operates on a two-wire loop-powered principle, simplifying installation while maintaining stable signal transmission for industrial monitoring systems.

This device is typically deployed in applications where space constraints, wiring simplicity, and reliable analog output are critical.

Operating Principle

The transmitter works with eddy current sensing technology to detect relative displacement between the probe tip and the conductive target surface. The measured signal is internally conditioned and converted into a proportional 4–20 mA output, suitable for direct integration into PLC or DCS systems.

Its loop-powered design eliminates the need for a separate power supply, reducing wiring complexity and improving system robustness.
