When combined with a 3300 XL Proximitor sensor and XLextension cable, the system provides an output voltage thatis directly proportional to the distance between the probe tipand the observed conductive surface. The system canmeasure both static (position) and dynamic (vibration) data.its primary use is in vibration and position measurementapplications on fluid-film bearing machines, as well asKeyphasor measurement and speed measurementapplications6.

The system provides an accurate, stable signal output over awide temperature range. All 3300 XL Proximity TransducerSystems achieve this level of performance with completeinterchangeability of probe, extension cable, and Proximitorsensor, eliminating the need for individual componentmatching or bench calibration.

Frequently Asked Questions

Q1: What is the Bently Nevada 330171-00-12-05-02-CN?

A1: It is a 3300 series 5 mm proximity probe designed for non-contact measurement of vibration and shaft displacement in rotating machinery.

Q2: What does “330171” indicate?

A2: “330171” identifies the probe as a 3300 series 5 mm probe with a 1/4-28 UNF thread, supplied in a standard version without armor.

Product Applications

Petroleum processing and refining plants: Used to monitor the operating status of large centrifugal compressors, turbines, and pump sets.

Power plants: Installed on steam turbines, gas turbines, and generator sets, they are a key input for their safety protection systems (such as the Bently Nevada 3500 system).

Steel and metallurgical plants: Monitor the mechanical integrity of large fans, blowers, and rolling mill drive systems.

Mining and cement plants: Used for monitoring the transmission shafts of large crushers and mills.
