Bently Nevada 330703-000-060-10-02-00 3300 XL 11 mm Proximity Probe

Description

330703-000-060-10-02-00 is an unarmored, metric M14 x 1.5 threaded 3300 XL 11 mm proximity probe configured with a 0 mm unthreaded length (fully threaded case) and a 60 mm total case length. It features a 1.0 meter (3.3 feet) standard triaxial cable terminated with a miniature coaxial ClickLoc connector and is supplied under the Option 00 standard (no agency approval required) package.

This configuration differs from standard 330701 probes by employing an M14 x 1.5 metric thread instead of standard fractional English threads, permitting direct installation in metric machinery housings. The unarmored 1.0-meter cable connects to a matching 3300 XL extension cable within a 5.0-meter or 9.0-meter transducer system, transmitting displacement signals representing shaft vibration, rotor position, or speed on turbines, compressors, and rotating machinery.

Features

• M14 x 1.5 metric thread (Option 330703 base) with an unarmored AISI 304 stainless steel case.
• 0 mm unthreaded length (Option 000) allowing maximum threaded insertion.
• 60 mm overall case length (Option 060) for specific machinery housing depths.
• 1.0 meter (3.3 feet) standard FEP-insulated triaxial cable (Option 10).
• Miniature coaxial ClickLoc connector (Option 02) without a connector protector.
• General area installation support (Option 00) where hazardous area certification is not required.
• 11 mm probe tip diameter providing a 4.0 mm (160 mil) linear measurement range.

Applications

• Steam turbine ramp differential expansion monitoring.
• Reciprocating compressor rod drop and rod position measurements.
• Industrial gas turbine and compressor shaft vibration and axial thrust position tracking.
• Tachometer and zero-speed shaft measurements.
• Phase reference (Keyphasor) signal generation.

Installation Guidelines

Ensure correct mechanical installation of the metric M14 x 1.5 probe body. Do not exceed the maximum rated case torque of 63.3 N-m (560 in-lb); a mounting torque of 21.1 N-m (187 in-lb) is recommended. The unthreaded length must be selected carefully to prevent probe tip contact with the target during machine operation. Keep the coaxial connector clean and dry. Finger-tighten the coaxial ClickLoc connector connection and secure using standard practice. Ensure the minimum cable bend radius of 25.4 mm (1.0 in) is maintained throughout cable routing. For environmental protection, use a connector protector or appropriate self-fusing silicone tape on the probe-to-extension cable connection if exposed to liquids or turbine oils.

Compliance and Certifications
