Bently Nevada 330102-00-10-10-01-05 3300 XL 8 mm Proximity Probe

Description

Fully threaded 3/8-24 UNF steel armored probe body (Option 00) with a 1.0 in case length (Option 10) and a 1.0 m total length (Option 10) defines this Bently Nevada 330102-00-10-10-01-05 proximity probe configuration. It operates using the non-contact eddy-current measurement principle to capture static (displacement) and dynamic (vibration) measurements of a rotating shaft. The system relies on pairing this physical probe with a compatible 3300 XL extension cable and a 3300 XL Proximitor Sensor to complete the measurement loop.

Unlike standard unarmored configurations, this armored variant includes an integrated flexible stainless steel armor sleeve designed to protect the coaxial cable from abrasive forces, sharp edges, and severe physical impacts. It comes pre-equipped with a miniature coaxial ClickLoc connector encased in an integrated fluorosilicone connector protector (Option 01). This protective assembly shields the delicate signal junction from water, lubricating fluids, turbine oils, and environmental moisture, ensuring steady transducer loop transmission in demanding industrial machinery environments.

Features

• Option 00 unthreaded design provides a fully threaded body across the entire case length to allow maximum flexibility in mounting brackets.
• Option 10 case length provides a 1.0 in (25.4 mm) steel body, suitable for tight mechanical spaces.
• Option 10 total length delivers a 1.0 meter (3.3 feet) integrated cable assembly.
• Option 01 connector includes a pre-installed fluorosilicone connector protector around the gold-plated male ClickLoc junction.
• Option 05 agency approval certifies the probe for CSA, ATEX, and IECEx hazardous area applications when installed with safety barriers.
• Flexible stainless steel armor sheath safeguards the FEP coaxial insulation from mechanical damage.
• Polyphenylene sulfide (PPS) tip material stands up to chemical deterioration and operating temperatures up to 177 degC.

Applications

This proximity probe is used for shaft vibration and axial position measurement on heavy industrial rotating machines. Typical applications include monitoring steam turbines, gas turbines, centrifugal compressors, reciprocating compressors, industrial gearboxes, high-pressure pumps, and large electric motors. It is specifically selected for harsh machine environments where the sensor cabling faces mechanical wear, debris, or fluid splashing.

Installation Guidelines

To ensure steady measurements, avoid scratching, dinging, or applying torque directly to the PPS plastic probe tip during placement. Do not exceed the maximum recommended thread engagement of 0.563 in (14.3 mm) for the 3/8-24 UNF-2A thread to prevent mechanical binding or cross-threading inside bracket bodies. Keep a minimum radial clearance of 3 times the probe tip diameter (24.0 mm) from surrounding conductive metal to avoid calibration errors. Always use a proper coaxial connector torque wrench or finger-tighten securely; avoid squeezing the gold-plated male pins with pliers. Cable routing must be arranged to prevent sharp kinks or bends beyond the minimum static bend radius of 30 mm.

Compliance and Certifications

This assembly complies with Option 05 hazardous area certification standards. The system holds intrinsic safety (Ex ia IIC) and non-incendive classifications under CSA, ATEX, and IECEx frameworks when installed in accordance with standard Bently Nevada drawing procedures and connected to barriers.
