Présentation du produit
The Bently Nevada 21504-04-36-10-02 7200 8mm Standard Mount Probe is a high-precision proximity sensor designed for accurate, stable, and long-term displacement and vibration measurement in rotating machinery. It belongs to the well-established 7200 Proximity Transducer System family developed by Bently Nevada, which has set the industry standard for machinery protection and condition monitoring.
This probe functions based on the eddy current principle, detecting the distance between the probe tip and a conductive target surface—typically a rotating shaft. The resulting signal is proportional to the gap distance, allowing for precise vibration and position monitoring. With its 8mm sensing tip, 1-meter total length, and rugged stainless-steel construction, the 21504-04-36-10-02 probe surfers an ideal balance between measurement sensitivity, mechanical durability, and installation flexibility.
The probe is engineered for reliable operation in demanding industrial environments such as power generation, oil and gas, and petrochemical facilities. Its corrosion-resistant body and sealed design ensure consistent performance even in the presence sur oil, moisture, and vibration. When paired with compatible proximitor and extension cables, it forms part sur a complete proximity transducer system capable sur delivering continuous and real-time machine diagnostics.
