Product Introduction
The Bently Nevada 21504-04-36-05-02 7200 8mm Standard Mount Probe is a precision-engineered proximity probe designed for use in industrial vibration and displacement measurement systems. This probe is part of the proven 7200 Proximity Transducer System family, developed by Bently Nevada for continuous machinery monitoring and protection.
The 21504-04-36-05-02 model is specifically designed to measure the relative motion and position between a rotating shaft and the probe tip with exceptional accuracy and stability. It operates based on the eddy current principle, producing a voltage proportional to the distance between the probe and the target surface. This makes it ideal for detecting shaft vibration, axial position, and phase reference signals in turbines, compressors, and critical rotating equipment.
Constructed with corrosion-resistant materials and encapsulated in a robust housing, this probe ensures reliable performance in harsh industrial environments, including high temperatures, oil exposure, and high vibration zones. Its 8 mm tip design provides a balance of sensitivity and robustness, making it one of the most widely used probe types in the field of condition monitoring.
