The Bently Nevada 18745-03 is a 5mm / 8mm Proximitor Sensor in the 7200 Series. It is a non-contacting, gap-to-voltage transducer system that measures both static and dynamic distances between the probe tip and the observed target. The sensor has a range of 5mm to 8mm and an accuracy of ±25µm. It is also side-shielded to reduce the effects of target misalignment.

Applications

Vibration Monitoring: The sensor measures the vibration of rotating machinery like pumps, motors, and turbines. This information helps in detecting and diagnosing faults in the machinery.

Position Monitoring: The sensor measures the position of objects such as shafts, gears, and valves. This data aids in machinery control and provides feedback to operators.

Gap Measurement: The sensor measures the gap between two objects, such as the clearance between a bearing and a shaft. This ensures proper machinery alignment and prevents wear and tear.
