Bently Nevada 330703-000-070-10-02-00 3300 XL 11 mm Proximity Probe

Description

330703-000-070-10-02-00 specifies this 3300 XL 11 mm proximity probe configuration featuring an M14 x 1.5 metric thread without armor, a fully threaded case with 0 mm unthreaded length, a 70 mm overall case length, a 1.0-meter total length, a standard cable with a miniature coaxial ClickLoc connector, and no agency approvals.

This non-contact eddy-current displacement sensor is used in 3300 XL 11 mm transducer systems to measure vibration and axial position on fluid-film bearing machines. The probe tip and body design provide a linear measurement range of 4.0 mm, which is wider than standard 8 mm probes. It operates alongside the 330780 Proximitor Sensor and 330730 extension cable to transmit displacement measurements back to 3500 or compatible machinery protection monitors.

Features

• Metric M14 x 1.5 threaded stainless steel body with no protective armor.
• Fully threaded 70 mm overall case length with 0 mm unthreaded length option.
• 1.0-meter integrated probe lead length.
• Standard triaxial cable jacket with a miniature coaxial ClickLoc connector.
• Linear range of 4.0 mm (160 mils) with an incremental scale factor of 3.94 V/mm (100 mV/mil).
• Sealed tip configuration using polyphenylene sulfide (PPS) and Viton O-ring seals.

Applications

• Axial thrust position measurements on steam turbine rotors and industrial compressors.
• Ramp differential expansion measurements on heavy steam turbines.
• Rod drop and rod position tracking in industrial reciprocating compressors.
• Phase reference (Keyphasor) and speed tracking measurements on critical rotating machinery.

Installation Guidelines

• Case Torque: Tighten the M14 x 1.5 probe body to the recommended torque of 21.1 N-m (187 in-lb). Do not exceed 63.3 N-m (560 in-lb) to prevent damage to the metric thread.
• Connector Care: Finger-tighten the ClickLoc coaxial connector when attaching the extension cable. Ensure connections are clean and dry; do not apply silicone tape if exposed directly to turbine oil.
• Cable Bend Limits: Route the probe lead maintaining a minimum bend radius of 25.4 mm (1.0 in) to prevent internal core damage.
• Gap Adjustment: Adjust the installation position until the gap matches the nominal 2.5 mm (100 mils) target setting.

Compliance and Certifications

• CE Mark: Complies with European Union EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU.
• Electromagnetic Compatibility: Meets EN 61000-6-2 (Industrial Immunity) and EN 61000-6-4 (Industrial Emissions).
• China RoHS: Environment-Friendly Use Period (EFUP) of 15 years.
