Bently Nevada 330730-040-03-05 3300 XL 11 mm Extension Cable

Description

330730-040-03-05 is a 4.0-meter 3300 XL 11 mm extension cable configured with flexible stainless steel armor, an integrated ClickLoc connector protector, and multiple hazardous area approvals. This cable is used for non-contact eddy-current displacement measurements within Bently Nevada 3300 XL 11 mm proximity transducer chains, connecting the 11 mm proximity probe to the 330780 Proximitor sensor.

In contrast to standard unarmored options, the Option 03 configuration provides mechanical protection using a flexible AISI 302 stainless steel armor sleeve with a protective FEP outer jacket. It also includes pre-installed male and female ClickLoc connector protectors to seal the electrical couplings from moisture, oil, and environmental contaminants, maintaining steady signal transmission under tough physical conditions.

Features

• Cable length of 4.0 meters (13.1 feet) designated by Option 040.
• Option 03 features flexible AISI 302 stainless steel armor with an outer FEP jacket for high mechanical and environmental resistance.
• Equipped with miniature coaxial ClickLoc connectors and a pre-installed connector protector kit.
• Low-capacitance FEP insulated triaxial construction preserving high-frequency signal integrity.
• Option 05 delivers multiple safety certifications for hazardous environments.
• Wide operating temperature range optimized for industrial rotating machinery monitoring.

Applications

• Turbine and compressor shaft vibration measurement
• Axial rotor position monitoring
• Machinery protection systems in oil, gas, and power generation plants
• Environments requiring physical armor protection against routing wear or chemical exposure

Installation Guidelines

• Always verify that the sum of the extension cable length and the proximity probe length equals the total system length expected by the Proximitor sensor (e.g., a 1.0 m probe plus this 4.0 m cable matches a 5.0 m system).
• Observe the minimum bend radius of 25.4 mm (1.0 in) when routing the cable through conduit or trays to avoid internal core fractures.
• Ensure the connector protectors are fully joined and sealed. For high-humidity or wet areas, use the connector protector kit to safeguard against water ingress. Do not use silicone self-fusing tape if turbine oil contact is expected.
• Tighten the coaxial connectors to finger-tight, or to a maximum of 0.565 N-m (5 in-lb) of torque with specialized fitting tools to protect gold-plated pins.

Compliance and Certifications

• EMC Directive 2014/30/EU (EN 61000-6-2, EN 61000-6-4)
• RoHS Directive 2011/65/EU
• Multiple Approvals (Option 05): ATEX, IECEx, CSA, Class I, Division 1 and 2, Zone 0, Zone 2 (Intrinsic Safety and Non-Incendive certifications when installed per drawings 141092 / 140979)
