Bently Nevada 330730-080-02-00 3300 XL 11 mm Extension Cable

Description

330730-080-02-00 specifies a Bently Nevada 3300 XL 11 mm extension cable configuration featuring an 8.0-meter length and a standard FEP-insulated coaxial design equipped with a connector protector. This cable serves as the signal transmission path between a 3300 XL 11 mm proximity probe and a 3300 XL 11 mm Proximitor Sensor, allowing for non-contact eddy-current displacement measurement within rotating machinery monitoring chains.

Unlike armored variants (such as Option 01 or 03) which include stainless steel protective conduit over the cable, this standard unarmored configuration (Option 02) is ideal for routing through existing conduit or cable trays while maintaining high physical flexibility. It includes an integrated slide-on connector protector to protect the ClickLoc coaxial connection point from moisture, dirt, and turbine oil, avoiding the need for field-applied silicone tape. This 8.0-meter cable must be matched with a compatible 1.0-meter proximity probe to form a complete 9.0-meter transducer system.

Features

• Option 080 specifies an 8.0-meter (26.2 feet) cable length.
• Option 02 includes standard unarmored coaxial cable with an integrated environmental connector protector.
• Option 00 designates that no specific hazardous area agency approvals are required for this component.
• 75 ohm triaxial construction with fluoroethylene propylene (FEP) insulation.
• Gold-plated brass ClickLoc coaxial connectors ensure secure signal coupling.

Applications

• Axial thrust position monitoring on large steam and gas turbines.
• Ramp differential expansion measurements in power generation applications.
• Piston rod position and rod drop measurements on reciprocating compressors.
• Shaft vibration and Phase reference (Keyphasor) speed measurements.
• Petrochemical, water treatment, and mining rotating machinery protection.

Installation Guidelines

When installing the extension cable, preserve a minimum bend radius of at least 25.4 mm (1.0 in) throughout the cable run to prevent core conductor degradation. Ensure that the gold-plated miniature ClickLoc connectors are completely dry, clean, and free of lubricants before mating. Hand-tighten the coaxial connectors, or use a torque wrench to tighten to the recommended maximum limit of 0.565 N-m (5 in-lb).

The integrated connector protector must be properly slid over the connection interface to keep out machinery oil and moisture. Do not apply silicone self-fusing tape inside the casing of the machine. Always verify that the combined length of the proximity probe (such as 1.0 meter) and the extension cable (8.0 meters) equals the total system length configured on the companion Proximitor Sensor (9.0 meters total system length).

Compliance and Certifications

• CE Mark compliant (EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU).
• China RoHS EFUP designation compliant for electrical cables.
