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

Description

330730-080-00-00: 3300 XL 11 mm extension cable, configured with an 8.0 m cable length (Option 080), standard unarmored coaxial cable (Option 00), and no agency approvals (Option 00). This cable connects a 3300 XL 11 mm proximity probe to a 3300 XL 11 mm Proximitor sensor, establishing the necessary physical and electrical path for non-contact eddy-current displacement measurement. The total system length (probe plus extension cable) must equal the calibration length of the Proximitor sensor, which is typically 9.0 m when pairing this 8.0 m cable with a 1.0 m probe.

Unlike variants equipped with stainless steel armor (Option 01) or connector protectors (Option 02), this specific model utilizes standard unarmored FEP insulation. This provides a lightweight, highly flexible routing profile ideal for conduit runs and protected cable trays where mechanical abrasion and liquid submersion risks are minimal. The integrated gold-plated brass ClickLoc connectors prevent mechanical loosening under machinery vibration.

Features

• 8.0 Meter Cable Length: Specified by Option 080 to provide the exact physical reach needed to form 9.0 m total system lengths when paired with 1.0 m probes.
• Standard FEP Insulation: Fluoroethylene propylene (FEP) outer jacket offers high chemical and temperature resistance without the added weight and rigid bend radius of steel armor.
• Gold-Plated ClickLoc Connectors: Gold-plated brass coaxial connectors lock securely to prevent accidental decoupling and maintain consistent electrical contact.
• 75 Ohm Impedance: Matches the impedance profile of 3300 XL 11 mm transducer systems to preserve signal integrity and avoid transmission reflections.
• No Agency Approvals Required: Option 00 specifies a non-certified variant, simplifying installations in general purpose or non-hazardous plant locations.

Applications

• Power generation gas and steam turbines
• Centrifugal and reciprocating compressors
• Industrial fans, pumps, and generators
• Shaft radial vibration monitoring and axial thrust position measurement
• Retrofitting existing 11 mm non-contact transducer chains

Installation Guidelines

Ensure that the extension cable length (8.0 m) combined with the probe length (1.0 m) matches the calibrated length of the Proximitor sensor (9.0 m) for accurate calibration and linear range output. When routing the cable, avoid sharp bends and maintain a bend radius greater than 25.4 mm (1.0 in). Use insulated cable clamps or conduit to prevent the cable from chafing against metal structures. Tighten ClickLoc connectors to finger-tight status; do not exceed 0.565 N-m (5 in-lb) of torque. For humid or wet environments, the use of silicone tape or connector protectors is recommended at the probe-to-extension-cable connection to prevent moisture ingress (note: silicone tape is not recommended if exposed to turbine oil).
