Bently Nevada 87055-01 Proximity Sensor Product Detailed Introduction and Technical Specification
1. Product Introduction
The 87055-01 is an industrial proximity sensor component designed for accurate measurement and monitoring of rotating machinery operating conditions.
The product is mainly used for non-contact measurement of shaft displacement, vibration movement, and mechanical position changes in critical rotating equipment. It uses eddy current sensing technology to detect the relative distance between the sensor probe and the rotating shaft surface without direct physical contact.
The non-contact operating principle allows the sensor to maintain stable measurement performance during long-term operation. Since there is no mechanical contact between the sensor and the monitored shaft, the system avoids wear caused by friction and provides improved reliability.
The 87055-01 is designed for machinery condition monitoring applications where accurate position measurement, vibration detection, and reliable operation are required.
The product is commonly applied in industrial rotating equipment such as turbines, compressors, generators, motors, pumps, and other high-speed machinery.
During equipment operation, the sensor continuously measures shaft movement and provides important information for machinery protection systems. The collected signals help maintenance personnel evaluate equipment health and identify possible problems before serious failures occur.
Typical mechanical conditions detected through this type of sensor include:
- Excessive shaft vibration
- Rotor imbalance
- Shaft misalignment
- Bearing wear
- Rotor instability
- Abnormal mechanical movement
The 87055-01 provides a practical monitoring solution for industrial applications requiring reliable and continuous machine condition evaluation.
