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.
