Quick Detail

Description

The 128987-130-00-CN 3300 XL 8mm Proximity Sensor Probe is an integral part of the Bently Nevada monitoring system. It measures the difference or clearance between the probe tip and the surface of a target, typically a rotating shaft, to detect changes in position or vibration. Engineered with a rugged stainless steel body, this probe is built to withstand harsh environments while providing reliable and accurate measurements. Its 8mm tip is ideal for applications requiring compact yet powerful proximity sensing. The probe is equipped with a factory-installed cable and connector for easy installation and integration into existing systems. The Bently Nevada 128987-130-00-CN 3300 XL 8mm Proximity Sensor Probe is part of a system designed to monitor machine health. It works by generating an eddy current field at the tip of the probe, which interacts with the target surface. Variations in the differential distance alter the eddy current field, which is processed to provide real-time data on machine position and vibration. This probe's rugged construction and advanced shielding ensure high performance, even in high-EMI environments. The stainless steel body resists corrosion, while the PEEK tip ensures accurate measurements over extended periods.

Applications

Vibration Monitoring on Rotating Shafts
