Bently Nevada 330707-00-20-10-02-00 3300 XL 11 mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length), Option 20 (2.0 in case length), and Option 10 (1.0 m total length) specify this 3300 XL 11 mm non-contact proximity probe configuration — 330707-00-20-10-02-00. This unarmored probe features a standard 5/8-18 UNF-2A thread (base model 330707) and standard coaxial cable terminating in a miniature ClickLoc connector without a connector protector (Option 02). This configuration does not include specific hazard area approvals (Option 00).

Operating as part of a 3300 XL 11 mm transducer system, this probe works alongside a 3300 XL 11 mm extension cable and a 3300 XL 11 mm Proximitor Sensor. It provides a 3.94 V/mm (100 mV/mil) output for measuring non-contacting vibration and displacement. The 11 mm tip diameter yields a 4.0 mm (160 mils) linear range, which is wider than standard 8 mm transducer systems, making it suitable for axial position, ramp differential expansion, and reciprocating compressor rod drop applications.

Features

• Thread and housing: 5/8-18 UNF thread without armor (base model 330707)
• Unthreaded length (Option 00): 0.0 in (fully threaded case)
• Overall case length (Option 20): 2.0 in
• Total length (Option 10): 1.0 meter (3.3 feet)
• Cable and connector (Option 02): Miniature coaxial ClickLoc connector, standard cable
• Agency approval (Option 00): Not required
• Wider linear range: 4.0 mm (160 mils) linear range beginning approximately 0.5 mm (20 mils) from the target
• Interchangeability: Fully compatible with other components of the 3300 XL 11 mm Transducer System

Applications

• Axial (thrust) position measurements
• Ramp differential expansion measurements on steam turbines
• Rod position or rod drop measurements on reciprocating compressors
• Tachometer and zero speed measurements
• Phase reference (Keyphasor) signals
• Turbine and compressor shaft vibration and rotor position monitoring

Installation Guidelines

• Gap Setting: Align the probe tip to a recommended gap of 2.5 mm (100 mils) from the target surface for central linear range placement.
• Torque Limits: Do not exceed the maximum rated torque of 45.2 N-m (400 in-lb) for 5/8-18 UNF cases. The recommended installation torque is 15.2 N-m (133 in-lb).
• Thread Engagement: Maintain thread engagement within the maximum limit of 0.938 in (24 mm) to prevent binding or mechanical damage.
• Bend Radius: Avoid sharp bends in the FEP coaxial cable; maintain a minimum bend radius of 25.4 mm (1.0 in).
• Connector Handling: Finger-tighten ClickLoc coaxial connectors, then torque to a maximum of 0.565 N-m (5 in-lb) using a torque wrench. Do not use silicone tape on the connector area if exposed to turbine oil.
