Product Introduction
The Bently Nevada 22811-00-03-05-02 8 mm Standard Mount Probe is a non-contact eddy current proximity probe designed for measuring shaft vibration and displacement in rotating machinery. It is commonly used in machinery condition monitoring systems where accurate measurement of shaft movement is required to ensure safe and reliable equipment operation.
This probe works by generating an electromagnetic field at the probe tip. When a conductive metal target such as a rotating shaft moves within the sensing range, the electromagnetic field changes. These variations are converted into electrical signals that represent the distance between the probe tip and the shaft surface. The signals are then processed by monitoring systems to analyze vibration levels and shaft position.
The probe features a standard mounting design and an 8 mm diameter sensing tip, making it suitable for installation in many industrial machines including turbines, compressors, pumps, and generators. Its compact structure allows it to be mounted close to rotating components where precise displacement monitoring is required.
Engineered for demanding industrial environments, the probe provides stable measurement performance even in areas exposed to vibration, temperature changes, and oil contamination. It is frequently integrated into machinery protection systems to provide continuous monitoring of shaft vibration and displacement.
