Bently Nevada 109548-01 Proximity Probe

Bently Nevada 109548-01 Introduction

The Bently Nevada 109548-01 is a non-contact eddy current sensor designed for measuring shaft displacement. It employs eddy current technology to induce currents on the shaft, which are used to calculate displacement based on variations in these currents. This sensor is ideal for monitoring the condition of rotating machinery and detecting early signs of faults.

Operating Principle of Bently Nevada 109548-01

The Bently Nevada 109548-01 utilizes eddy current technology to measure shaft displacement. Eddy currents are induced in a conductor by a changing magnetic field. In this sensor, a coil generates an alternating magnetic field that induces eddy currents on the shaft. The intensity of these currents depends on the distance between the shaft and the sensor. By measuring the eddy current intensity, the displacement of the shaft can be accurately calculated.
