Bently Nevada 330704-000-100-10-01-05 3300 XL 11 mm Proximity Probe

Description

330704-000-100-10-01-05 is a 3300 XL 11 mm proximity probe with an M14 x 1.5 metric threaded body and protective stainless steel armor. This specific configuration features a fully threaded 100 mm case (0 mm unthreaded length) and a 1.0-meter total cable length ending in a miniature coaxial ClickLoc connector with an integrated connector protector. The integrated flexible AISI 302 stainless steel armor provides physical protection for the triaxial fluoroethylene propylene (FEP) insulated cable in industrial machinery environments.

This probe functions as part of a 3300 XL 11 mm proximity transducer system, which provides a 3.94 V/mm (100 mV/mil) electrical output representing the physical gap between the probe tip and a target. It is used with a 3300 XL 11 mm extension cable and a 3300 XL 11 mm Proximitor Sensor to measure axial position, radial vibration, differential expansion, or speed on rotating machinery such as turbines, compressors, and industrial pumps.

Features

• M14 x 1.5 threaded stainless steel probe body with standard protective stainless steel armor.
• Option 000 specifies 0 mm unthreaded length for maximum thread engagement.
• Option 100 specifies a 100 mm overall case length.
• Option 10 provides a 1.0-meter (3.3 feet) total cable length.
• Option 01 features a ClickLoc miniature coaxial connector equipped with a fluorosilicone connector protector.
• Option 05 designates multiple agency approvals for hazardous locations, including CSA, ATEX, and IECEx.
• Polyphenylene sulfide (PPS) probe tip material resists chemical and thermal exposure.

Applications

This 3300 XL 11 mm proximity probe configuration is used on heavy rotating machinery for the following measurements:

• Turbine shaft radial vibration and axial position monitoring.
• Ramp differential expansion measurements on steam turbines.
• Rod position or rod drop measurements on reciprocating compressors.
• Tachometer, zero speed, and Keyphasor phase reference signal measurements.

Installation Guidelines

To establish safe and accurate installation of the 3300 XL 11 mm Proximity Probe, observe the following parameters:

• Thread Engagement: Do not exceed the maximum thread engagement limit of 21 mm for M14 x 1.5 threads to prevent binding.
• Torque Limits: Hand-tighten the probe, then torque to the recommended 21.1 N-m (187 in-lb). Do not exceed the absolute limit of 63.3 N-m (560 in-lb).
• Bend Radius: Avoid twisting the cable and maintain a minimum bend radius of 25.4 mm (1.0 in) along the armored cable run.
• Connector Protection: Ensure the connector protector is clean and dry. Finger-tighten coaxial connections; do not use pliers.
• System Matching: Confirm that the combined length of the probe and extension cable matches the design length of the 3300 XL Proximitor Sensor (5.0 m or 9.0 m total system length).
