Emerson PR6423 Eddy-Current Displacement Sensor

From:Emerson | author:Mr.Chen | Time :2024-09-02 | 165 view: | Share:

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 hydraulic 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, there is a thin film of oil between the shaft and the bearing material.

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

The use of bearing box vibration sensors to monitor sleeve bearing machines is discouraged because vibration from shaft motion or position is greatly attenuated through the bearing oil film.

The ideal method of monitoring shaft position and motion is to measure shaft motion and position directly through the bearing or by installing a non-contact eddy current sensor inside the bearing.

The PR 6423 is commonly used to measure vibration in the following equipment

eccentricity, thrust (axial displacement), differential expansion, valve position and air gap.

Non-contact measurement of static and dynamic shaft displacements

- Axial and radial shaft displacement (position)

- Shaft eccentricity

- Shaft vibration (motion)

Meets international standards DIN 45670. ISO 10817-1 and API 670

Rated for use in explosive areas, Eex ib IIC T6/T4

Other displacement transducer options include PR 6422. PR 6423. PR 6424. and PR 6425
