Bently Nevada 330703-000-040-10-11-00 3300 XL 11 mm Proximity Probe

Description

Option 000 (0.0 mm unthreaded length) and Option 11 (coaxial ClickLoc connector with connector protector, FluidLoc cable) specify this metric unarmored 3300 XL 11 mm Proximity Probe configuration — 330703-000-040-10-11-00.

This specific metric-threaded probe features an M14 x 1.5 thread without armor, a 40 mm overall case length, and a 1.0 meter (3.3 feet) total cable length. The integrated FluidLoc cable prevents fluid leakage along the inner conductors of the cable, making it suitable for environments where oil or other pressurized fluids are present at the mounting point. This transducer probe is compatible with the 3300 XL 11 mm transducer system, operating in conjunction with a 3300 XL 11 mm extension cable and a 330780 Proximitor Sensor.

Features

• M14 x 1.5 metric threaded case (without armor) for direct mounting.
• 0.0 mm unthreaded length (fully threaded case) and 40 mm overall case length.
• 1.0 meter (3.3 feet) total length with FluidLoc cable option to prevent fluid tracking.
• Miniature coaxial ClickLoc connector pre-installed with a fluorosilicone connector protector.
• 4.0 mm (160 mils) linear range with a recommended gap setting of 2.5 mm (100 mils).
• Polyphenylene sulfide (PPS) tip material and AISI 304 stainless steel case.

Applications

• Axial (thrust) position measurements on steam turbines and utility turbo-machinery.
• Radial vibration and position monitoring on fluid-film bearing rotating machinery.
• Ramp differential expansion measurements on steam turbines.
• Rod position and rod drop measurements on reciprocating compressors.
• Phase reference (Keyphasor) and speed measurements.

Installation Guidelines

To ensure optimal performance and mechanical longevity of the 3300 XL 11 mm Proximity Probe, adhere to the following installation guidelines:

• Thread Engagement: Do not exceed the maximum rated torque of 63.3 N-m (560 in-lb) for the M14 x 1.5 thread. The recommended installation torque is 21.1 N-m (187 in-lb).
• Thread Depth: The maximum thread engagement length for M14 x 1.5 threads is 21 mm. Exceeding this may cause binding or damage.
• Cable Protection: Maintain a minimum cable bend radius of 25.4 mm (1.0 in) for the unarmored FluidLoc cable.
• Connector Care: Hand-tighten the miniature coaxial ClickLoc connectors. Do not exceed 0.565 N-m (5 in-lb) of torque. Ensure the pre-installed fluorosilicone connector protector is properly seated to prevent moisture and oil ingress.
• Target Alignment: Ensure the target surface area is at least 30.5 mm (1.2 in) in diameter and composed of AISI 4140 steel for optimal calibration and accuracy.
