Emerson PR 6423 Non-Contact Eddy Current Sensor

The PR 6423 is a non-contact eddy current sensor of rugged construction designed for extremely critical turbomachinery applications, such as steam, gas, compressor and water turbomachinery, blowers and fans.

Examples include steam, gas, compressor and water turbomachinery, blowers and fans.

The purpose of the displacement probe is to measure position or shaft motion without contacting the surface under test (rotor).

In sleeve bearing machines, a thin film of oil separates the shaft from the bearing material.

The oil acts as a damping agent so that shaft vibrations and position are not transmitted through the bearing to the bearing housing.

Vibrations due to shaft movement or position are greatly attenuated by the action of the bearing oil film.

The use of housing vibration sensors to monitor sleeve bearing machines is therefore discouraged.

The ideal method of monitoring shaft position and motion is through the bearing or a non-contact eddy current sensor mounted inside the bearing.

PR 6423 is commonly used to measure machine shaft vibration, eccentricity, thrust (axial displacement), differential expansion, valve position and air gap.

Non-contact measurement of static and dynamic shaft displacements

- Shaft and radial displacement (position)

- Shaft eccentricity

- Shaft vibration (motion)
