Bently Nevada 330101-12-30-10-02-CN 3300 XL 8 mm Proximity Probe

Description

Designed for critical machinery monitoring, the 330101-12-30-10-02-CN represents a high-precision sensor within the Bently Nevada 3300 XL 8 mm Proximity Probes product line. This industrial-grade proximity probe is engineered to measure static (position) and dynamic (vibration) parameters on rotating shaft machinery, interfacing directly with 3300 XL Proximitor Sensors to deliver reliable eddy current measurements.

By utilizing a 3/8-24 UNF thread housing without armor, this transducer facilitates accurate gap measurements in demanding industrial settings such as steam turbines, gas turbines, compressors, and pumps. Its design provides excellent resistance to harsh media, ensuring long-term mechanical stability and signal integrity under continuous operation.

Features

• Standard 8 mm probe tip diameter featuring polyphenylene sulfide (PPS) construction.
• AISI 303 and AISI 304 stainless steel case providing robust physical protection.
• ClickLoc miniature coaxial connector for secure, vibration-resistant cable coupling.
• Unthreaded length of 1.2 inches combined with a 3.0-inch overall case length.
• Standard unarmored cable construction with a total length of 1.0 meter (3.3 feet).
• Exceptional thermal performance across wide operating temperature envelopes.

Applications

• Steam and gas turbines
• Centrifugal and reciprocating compressors
• Industrial pumps and heavy-duty fans
• Hydroelectric generators
• General rotating machinery vibration and axial position monitoring

Installation Guidelines

• Ensure the mounting bracket or machine housing is prepared with a compatible 3/8-24 UNF threaded port.
• Observe the 1.2-inch unthreaded and 3.0-inch overall case dimensions to avoid bottoming out or damaging the probe tip during installation.
• Perform mechanical gap calibration using a voltmeter connected to the Proximitor Sensor output prior to final tightening.
• Observe minimum bend radius guidelines for the coaxial cable to prevent internal conductor damage.
• Route cables through dedicated conduits or trays away from high-voltage AC lines to minimize signal noise.
