Description

The Bently Nevada 330801-28-00-050-03-02 provides non-contact shaft vibration and displacement measurement as part of the 3300 XL 8 mm Proximity Transducer System. The probe detects changes in the distance between the probe tip and the conductive shaft surface using eddy current sensing technology. The measurement signal is transmitted through a compatible extension cable to the Proximitor Sensor, where it is converted into an output for machinery monitoring systems. The 330801-28-00-050-03-02 configuration includes a 50 mm case length, allowing installation in machinery with limited mounting space while maintaining compatibility with the 3300 XL 8 mm transducer system. The probe is designed to operate with matched system components to provide stable measurement performance across the specified operating range. When installed as a complete transducer system, the probe supports continuous monitoring of shaft vibration, shaft position, radial displacement, and axial movement. The non-contact measuring principle eliminates physical contact with rotating components, making the system suitable for continuous operation on high-speed rotating equipment.

Frequently asked questions

Q:What is the primary function of the Bently Nevada 330801-28-00-050-03-02?
A:Provides non-contact measurement of shaft vibration, displacement, and position by detecting the gap between the probe tip and a conductive target as part of the 3300 XL 8 mm Proximity Transducer System.

Q:What measurements can be obtained with the 330801-28-00-050-03-02?
A:When used as part of a complete transducer system, the probe supports radial vibration measurement, shaft displacement monitoring, axial position measurement, and shaft position monitoring.

Q:Why is system matching important?

A:Using the correct probe, extension cable, and Proximitor Sensor combination helps maintain the calibration and measurement performance specified for the 3300 XL 8 mm Proximity Transducer System.
