Bently Nevada 330703-000-100-10-02-00 3300 XL 11 mm Proximity Probe

Description

330703-000-100-10-02-00: 3300 XL 11 mm proximity probe with an M14 x 1.5 metric thread and no cable armor. This specific configuration is defined by a 100 mm fully threaded case (0 mm unthreaded length), a 1.0 meter standard triaxial cable, a miniature coaxial ClickLoc connector without a connector protector, and no agency approval requirements.

This proximity probe operates as a non-contact eddy-current displacement sensor within a 3300 XL 11 mm transducer system. It is designed to measure static position or dynamic vibration on critical rotating machinery, such as steam turbines, gas turbines, compressors, and gearboxes. The probe integrates with a 3300 XL 11 mm extension cable and a 330780 Proximitor Sensor to deliver a linear output voltage of 3.94 V/mm (100 mV/mil) over a 4.0 mm (160 mil) measurement range.

Features

• Metric thread design with a precision M14 x 1.5 thread and unarmored triaxial FEP cable.
• Fully threaded 100 mm case length (0 mm unthreaded) to suit deep mechanical recess mounting.
• Miniature coaxial ClickLoc connector locks securely to prevent loose coaxial connections.
• Gold-plated brass connector construction maximizes signal transmission integrity.
• Coaxial 75 ohm FEP triaxial standard cable provides high chemical and temperature resistance.
• TipLoc molding method delivers high-strength bonding between the PPS tip and stainless steel case.
• Locknut included with pre-drilled safety wire holes to ensure high vibration resistance.

Applications

• Industrial steam and gas turbine shaft vibration and axial position monitoring.
• Centrifugal compressor shaft position and radial vibration measurements.
• Generator rotor axial displacement and differential expansion tracking.
• Hydroelectric turbine guide bearing radial dynamic vibration detection.
• Rotating machinery protection in industrial, non-hazardous areas.

Installation Guidelines

• Verify that the target area diameter on the shaft is at least 30.5 mm to prevent edge effects and maintain system accuracy.
• Do not exceed a thread engagement length of 21 mm for the M14 x 1.5 probe case to avoid structural binding.
• Ensure the probe is tightened to the recommended torque of 21.1 N-m, and never exceed the maximum torque rating of 63.3 N-m.
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) during routing to prevent signal degradation or core damage.
• Exposing the probe tip to temperatures below -34 degC (-29 degF) may compromise the integrity of the pressure seal.
