Bently Nevada 330103-10-20-05-02-CN 3300 XL 8 mm Proximity Probe

Description

Option 10 (100 mm unthreaded length) and Option 20 (200 mm overall case length) specify this metric 330103-10-20-05-02-CN 3300 XL 8 mm proximity probe configuration. This non-armored probe features an M10 x 1 metric thread, a 0.5-meter (1.6 feet) total length, and a standard coaxial cable terminated with a miniature coaxial ClickLoc connector (Option 02). It is equipped with the -CN China hazardous area approval package, certifying it under NEPSI and CCC safety frameworks for explosion-proof applications in regional environments.

This non-contact eddy-current transducer is used in vibration and axial position measurement systems. It pairs with a 3300 XL Proximitor sensor and a 3300 XL extension cable to measure shaft displacement on rotating machinery such as pumps, compressors, and steam turbines. The M10 x 1 metric thread is suited for industrial equipment utilizing metric mounting ports. Because it lacks external armor, it is intended for installation within protective conduit or machinery internal areas.

Features

• Option 10 specifies a 100 mm unthreaded case length.

• Option 05 specifies a 0.5 meter (1.6 feet) total system cable length.
• Option 02 provides a miniature ClickLoc coaxial connector with a standard, non-armored cable.
• M10 x 1 metric thread configuration for direct installation in metric mounting ports.
• PPS (polyphenylene sulfide) molded tip provides electrical isolation and chemical resistance in oil-filled environments.
• Suffix -CN incorporates China national certifications, including NEPSI and CCC, for hazardous area zones.

Applications

• Rotating machinery shaft vibration monitoring.
• Axial shaft position and thrust displacement measurements.
• Keyphasor reference signal and rotational speed tracking.
• Fluid-film bearing machine monitoring in petrochemical, oil and gas, and power generation environments requiring China hazardous area certification.

Installation Guidelines

Ensure the unthreaded length is selected correctly so the probe does not contact the shaft during machine operation. Keep a minimum side-view clearance of 41.3 mm (1.625 in) from surrounding metal to avoid calibration interference. Tighten the probe body in its bracket or machine port; standard M10 x 1 threads support a maximum torque of 9.0 N-m (80 in-lb). Maintain a physical clearance when routing probe cables; use conduit or cable clamps to secure the cable run. Avoid tight bends; the minimum bend radius for standard cable is 25.4 mm (1.0 in).
