Probe Proksimit Bently Nevada 330703-000-050-10-01-00 3300 XL 11 mm

Description

Option 000 (0 mm unthreaded length), Option 050 (50 mm overall case length), and Option 01 (ClickLoc connector with connector protector, standard cable) define this 3300 XL 11 mm proximity probe configuration — 330703-000-050-10-01-00. This non-contact eddy-current displacement probe has an M14 x 1.5 metric thread and does not feature protective armor, allowing standard installation in machinery housings where physical shielding is handled by external conduit. It has a total electrical length of 1.0 meter and functions as a transducer sensor in industrial machinery protection systems.

The probe operates with a nominal linear range of 4.0 mm (160 mils), beginning approximately 0.5 mm from the target face. It is matched for use with a 3300 XL 11 mm Proximitor Sensor and compatible extension cables, converting physical displacement of rotating shafts into proportional electrical signals. The integrated connector protector guards the ClickLoc coaxial connection against contamination and moisture in industrial environments.

Features

• M14 x 1.5 metric thread with a 50 mm overall case length and 0 mm unthreaded section.
• ClickLoc miniature coaxial connector with a pre-installed fluorosilicone connector protector.
• 1.0 meter total electrical length, designed for 5.0 meter system configurations when paired with a 4.0 meter extension cable.
• Unarmored standard 75 ohm triaxial cable with fluoroethylene propylene (FEP) insulation.
• Polyphenylene sulfide (PPS) tip material with AISI 304 stainless steel probe case construction.

Applications

• Shaft vibration measurements on steam turbines, gas turbines, and large industrial compressors.
• Axial rotor position and radial dynamic motion monitoring on critical rotating machinery.
• Hydroelectric turbine shaft displacement and thermal expansion tracking.
• Industrial gearbox shaft alignment and thrust position diagnostics.

Installation Guidelines

Correct installation ensures the system functions within its specified linear range and maintains signal integrity:

• Probe Clearance: Ensure a minimum of 31 mm diameter of flat target surface is maintained. Keep surrounding metal at least 15.2 mm away from the probe tip to avoid side-viewing cross-talk.
• Case Torque: Do not exceed the maximum rated torque of 63.3 N-m (560 in-lb) during thread engagement to prevent casing deformation. The recommended installation torque is 21.1 N-m (187 in-lb).
• Cable Minimum Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the probe cable during routing to prevent internal coaxial damage.
• Connector Protection: Ensure the fluorosilicone connector protector is fully seated over the miniature ClickLoc connection to shield the coaxial junction from oil, moisture, and debris.
