Frequently asked questions
Q:What is the main function of the Bently Nevada 330881-16-11-165-07-02?
A:Provides non-contact eddy current measurement of shaft movement and displacement by detecting the gap change between the probe tip and the rotating shaft surface in a 3300 XL 8 mm Proximity Transducer System.

Q:What type of measurements can be performed with the 330881-16-11-165-07-02?
A:When installed as part of a complete 3300 XL 8 mm system, the probe supports shaft vibration measurement, radial displacement monitoring, axial position measurement, and other rotor movement monitoring applications.

Q:What components are required to complete the 330881-16-11-165-07-02 measurement system?
A:A complete measurement system normally includes the 3300 XL 8 mm proximity probe, compatible extension cable, and Proximitor Sensor to provide signal conversion and output to monitoring equipment.

Description

The Bently Nevada 330881-16-11-165-07-02 3300 XL 8 mm Proximity Probe is designed for use in the 3300 XL Proximity Transducer System to provide non-contact measurement of shaft vibration and position changes in rotating machinery. The probe operates with a compatible extension cable and Proximitor Sensor to detect the distance variation between the probe tip and the conductive shaft surface, converting mechanical movement into an electrical measurement signal. The 330881-16-11-165-07-02 configuration features a 16 mm probe length, 3/8-24 UNF threaded design, and a 165 mm case length, providing a suitable installation option for machinery applications requiring specific mounting dimensions. The probe incorporates the 3300 XL design with improved mechanical construction and reliable signal transmission characteristics for continuous monitoring systems. The probe uses eddy current sensing technology to measure relative shaft displacement without physical contact with the rotating component. When installed as part of a complete 3300 XL 8 mm Proximity Transducer System, it provides measurement signals used for radial vibration monitoring, axial position measurement, and other shaft movement monitoring applications. The 330881-16-11-165-07-02 is designed to operate with compatible Bently Nevada 3300 XL extension cables and Proximitor Sensors to form a complete proximity measurement chain.
