Bently Nevada 330171-00-12-10-01-CN 3300 XL 8mm Proximity Probe
The Bently Nevada 330171-00-12-10-01-CN is a 3300 XL 8mm Proximity Probe featuring a 3/8-24 UNF thread and a 1.0m cable. Certified for Chinese market standards (CN), it provides high-precision 2.0mm linear range sensing for vibration and position monitoring of critical rotating machinery.
Product Description
The Bently Nevada 330171-00-12-10-01-CN functions as a high-precision eddy current sensor within the 3300 XL 8mm Proximity Transducer System. This probe is designed to measure the static and dynamic distance between the probe tip and a target, such as a rotating shaft. Because it belongs to the 3300 XL family, it offers a linear range of 2.0 mm (80 mils) and provides a highly stable voltage output when paired with a 3300 XL Proximitor Sensor. The “CN” designation indicates that the module is specifically certified for use in the Chinese market, adhering to localized hazardous area standards.
Furthermore, the probe features a 3/8-24 UNF thread housing, making it a standard choice for industrial machinery monitoring. It utilizes a PPS (polyphenylene sulfide) tip that is resistant to high temperatures and corrosive lubricants. Since the probe converts mechanical displacement into an electrical signal, it allows the Bently Nevada 3500 Monitoring System to perform real-time vibration analysis and axial position tracking. Its robust mechanical design ensures that critical machinery—such as steam turbines, centrifugal compressors, and large motors—remains protected against catastrophic mechanical failure.

Technical Overview
The Bently Nevada 330192-00-28-05-00 is an 8 mm Extended Temperature Range (ETR) proximity probe component of the 3300 XL Proximity Transducer System. Its primary function is to perform non-contact measurement of relative displacement on rotating and reciprocating machinery. The probe operates on an eddy current principle. When paired with a 3300 XL extension cable and Proximitor Sensor, it forms a tuned oscillator circuit that emits a high-frequency radio frequency (RF) field from the probe tip. This field induces eddy currents on the surface of the observed conductive target, typically a machine shaft. The interaction between the RF field and the eddy currents results in a change in the oscillator's amplitude, which is directly proportional to the gap between the probe tip and the target. The Proximitor Sensor demodulates this RF signal into a precise DC voltage. This voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500 Series, where it is processed to provide critical measurements including radial vibration, axial position (thrust), and rotational speed (when used in a Keyphasor configuration). The 330192-00-28-05-00 is constructed with a Polyphenylene Sulfide (PPS) tip and a stainless steel body, ensuring robust performance in high-temperature industrial environments.
