Bently Nevada 330101-00-10-10-01-00 3300 XL 8 mm Proximity Probe

Description

330101-00-10-10-01-00: 3300 XL 8 mm proximity probe, 3/8-24 UNF thread, without armor, featuring 0.0 in unthreaded length, 1.0 in case length, 1.0 m (3.3 ft) total length, a miniature coaxial ClickLoc connector with a connector protector on standard cable, and no agency approval requirements.

This configuration is specified by Option 00 for unthreaded length and Option 10 for overall case length, providing a 1.0-inch fully threaded body. It includes a ClickLoc connector with integrated connector protection (Option 01) on a standard 1.0-meter non-armored FEP insulated coaxial cable. The probe measures static and dynamic shaft movement, and pairs with a 3300 XL Proximitor sensor and standard extension cable within a 3300 XL monitoring chain. The lack of physical armor suits installations with direct conduit runs or minimal exposure to abrasive machine parts.

This proximity probe operates on the eddy-current principle, generating an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. It is calibrated for use with an AISI 4140 steel target and offers backward compatibility with older non-XL 3300 series 5 mm and 8 mm system components. This specific variant does not carry hazardous area certifications, as defined by Option 00 for agency approvals.

Features

• Option 00 unthreaded design provides a fully threaded body along the entire 1.0 in case length.
• Option 10 total length specifies a 1.0 m (3.3 ft) integrated coaxial cable without protective metal armor.
• Option 01 connector configuration includes a miniature coaxial ClickLoc connector pre-installed with a protective connector sleeve.
• Option 00 agency approval designates a standard, non-hazardous area configuration with no certification requirements.
• Polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case resist common industrial machine environments.
• 75 ohm triaxial cable features fluorinated ethylene propylene (FEP) insulation to withstand standard machine casing operating temperatures.

Applications

• Steam and gas turbine shaft vibration and axial position monitoring.
• Compressor and pump rotor displacement measurements.
• Keyphasor reference and rotational speed measurements on rotating machinery.
• Fluid-film bearing clearance and shaft motion tracking.

Technical Specifications

Installation Guidelines

• Mount the probe using a suitable threaded mounting bracket or bearing housing tap, ensuring a proper thread engagement up to a maximum of 0.563 in (14.3 mm) for 3/8-24 threads.
• Establish the correct probe gap (typically -9 Vdc or approximately 1.27 mm / 50 mils) relative to the target shaft per system calibration requirements.
• Avoid over-tightening the probe case; apply a recommended torque of 11.2 N-m (100 in-lbf) up to a maximum limit of 33.9 N-m (300 in-lbf).
• Ensure the minimum bend radius of 25.4 mm (1.0 in) is maintained for the coaxial cable to prevent internal conductor damage.
• Route the triaxial cable through dedicated metal conduit or protective trays, keeping field wiring separate from high-voltage AC cables to minimize electromagnetic interference.
• Tighten the miniature coaxial ClickLoc connector finger-tight to secure the junction, then verify that the integrated connector protector is properly positioned.

Compliance and Certifications

• Agency Approvals: Standard non-hazardous area configuration (Option 00, no hazardous area approvals required).
• Electromagnetic Compatibility: Complies with CE requirements for industrial electrical equipment.
