Bently Nevada 330701-00-30-10-02-05 3300 XL 11 mm Proximity Probe

Description

Fully threaded 1/2-20 UNF steel probe body (Option 00 unthreaded) with a 3.0 in case (Option 30) and a 1.0 m lead (Option 10) specifies this 330701-00-30-10-02-05 3300 XL 11 mm proximity probe configuration.

This specific configuration includes a Miniature coaxial ClickLoc connector on a standard FEP-insulated coaxial cable (Option 02), supplied without a connector protector or protective armor. It is certified for hazardous areas under the Option 05 Multiple Approvals package, including ATEX, IECEx, and CSA standards for intrinsic safety and non-incendive installations. The 11 mm tip diameter provides an extended 4.0 mm linear range compared to standard 8 mm systems, rendering it suitable for larger-scale vibration and position measurements on rotating machinery.

Features

• Option 00 specifies a 0.0 inch unthreaded length for maximum thread engagement in the mounting bracket or machine housing.
• Option 30 provides a 3.0 inch overall case length, constructed from durable AISI 304 stainless steel.
• Option 10 provides a 1.0 meter (3.3 feet) integrated FEP-insulated coaxial cable to connect directly with a 3300 XL 11 mm extension cable.
• Option 02 defines a Miniature coaxial ClickLoc connector without a connector protector, using standard 75 ohm triaxial cable.
• Option 05 provides Multiple Approvals, making this probe suitable for deployment in Class I Division 1, Zone 0, and Zone 2 hazardous areas.
• Extended linear range of 4.0 mm (160 mils) accommodates larger axial movements and target gaps.

Applications

• Shaft vibration monitoring on large steam turbines, gas turbines, and industrial compressors.
• Axial thrust position measurement where larger target gaps require an extended linear range.
• Differential expansion monitoring on thermal rotating machinery.
• Rod drop and rod position measurements in reciprocating compressors.
• Phase reference (Keyphasor) and speed monitoring.

Installation Guidelines

• Maintain a minimum probe target gap of 2.5 mm (100 mils) to position the system output near the center of the -9 Vdc linear range.
• Ensure that probe casing thread engagement is secure. Torque standard 1/2-20 UNF casings to the recommended 15.2 N-m (133 in-lb) value, taking care not to exceed 45.2 N-m (400 in-lb).
• Avoid routing coaxial cables around sharp metal edges. Respect the minimum bend radius of 25.4 mm (1.0 in) to prevent internal conductor damage.
• Ensure that connections between the probe lead and extension cable are finger-tight; do not use pliers to tighten ClickLoc connectors.
• For hazardous area applications, install the proximity system in accordance with Bently Nevada control drawings 141092 (for intrinsically safe installations) or 140979 (for non-incendive environments).

Compliance and Certifications

• EMC: Standards EN 61000-6-2 (Industrial Immunity) and EN 61000-6-4 (Industrial Emissions) per European Community Directive 2014/30/EU.
• RoHS: Compliant with European Directive 2011/65/EU and China RoHS regulations (SJ/T 11364-2024 Environmentally Friendly Use Period of 15 years).
• Functional Safety: Certified for SIL 2 (HFT = 0) and SIL 3 (HFT = 1) applications under relevant safety-instrumented systems.
• Hazardous Area Approvals (Option 05): Certified by CSA (US and Canada), ATEX, and IECEx for intrinsic safety (Ex ia IIC T5...T1 Ga) and non-sparking/non-incendive environments (Ex nA/ec IIC T5...T1 Gc).
