Bently Nevada 330710-004-054-50-02-00 3300 XL 11 mm Proximity Probe

Description

330710-004-054-50-02-00 specifies a metric-threaded 3300 XL 11 mm proximity probe configuration, defined by an M16 x 1.5 threaded case with standard stainless steel armor, a 4 mm unthreaded length, a 54 mm overall case length, and a 5.0-meter integral cable length terminated with a miniature ClickLoc coaxial connector and no hazardous area approvals.

This non-contact eddy-current sensor is used for measuring dynamic vibration and static position of machine shafts. It is specifically designed for applications requiring an extended linear range of 4.0 mm (160 mils), such as steam turbine ramp differential expansion, rotor axial position, and reciprocating compressor rod drop monitoring. The integrated cable utilizes a miniature ClickLoc coaxial connector with gold-plated brass contacts, and is protected by a flexible stainless steel armor sleeve with an FEP outer jacket to shield the assembly from physical wear and harsh environmental elements. This 5.0-meter probe is designed to connect directly with a 5.0-meter 3300 XL Proximitor sensor without needing an additional extension cable.

Features

• M16 x 1.5 metric case thread with armor: Supplied with standard flexible AISI 302 stainless steel armor and an outer protective FEP jacket for high-durability mechanical protection in challenging industrial locations.
• 4 mm unthreaded and 54 mm case lengths (004-054): Pre-engineered metric dimensions designed for exact structural alignment within machinery housings.
• 5.0 m total integral length (50): Direct 5-meter system length matching designed specifically for pairing with 5.0-meter Proximitor sensors, reducing cable connection interfaces.
• Miniature ClickLoc coaxial connector (02): Gold-plated brass connector with a positive-locking design that prevents connection looseness from continuous machinery vibration.
• Polyphenylene sulfide (PPS) tip material: The 11 mm tip is constructed from PPS to resist erosion and degradation from industrial turbine lubricants and chemical fluids.
• CableLoc design resistance: The internal cable termination provides a robust 330 N (75 lb) pull strength from the probe tip to the lead wire.

Applications

• Steam turbine rotor ramp differential expansion and axial (thrust) position measurements.
• Rod drop and rod position tracking on industrial reciprocating compressors.
• Shaft vibration and radial displacement monitoring on high-speed rotating machinery.
• Tachometer, speed sensing, and phase reference (Keyphasor) signal generation.

Installation Guidelines

• Verify that the maximum unthreaded length of 4 mm (Option 004) is at least 26 mm shorter than the overall case length of 54 mm (Option 054).
• To prevent binding during installation, the maximum thread engagement length should not exceed 24 mm.
• Tighten the probe case to a recommended torque of 21.1 N-m (187 in-lb) and do not exceed the maximum rating of 63.3 N-m (560 in-lb).
• Maintain a minimum bend radius of 25.4 mm (1.0 in) along the run of the armored coaxial cable.
• Verify the probe gap is set to approximately 2.5 mm (100 mils) for optimal linear dynamic output range.
