The Bently Nevada 330104-16-21-10-01-05 3300 XL probe have corrosion-resistant,gold-plated ClickLoc connectors. These connectors require only finger-tight torque (the connectors will "click" when tight), and the specially-engineered locking mechanism prevents the connectors from loosening.

The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range,accuracy, and temperature stability. 

Application:
Oil and gas: Radial vibration and axial displacement monitoring for centrifugal compressors, pumps and turbines.
Power plants: Monitoring of thermal expansion, oil film vibration and key bearing conditions of steam turbines, gas turbines and generators.
Chemical plants: Mechanical protection for large fans, mixers and key pump sets.
Steel and metallurgical plants: Operation monitoring of blast furnace blowers and large power equipment.
