Bently Nevada 330877-80-37-00 3300 XL 50 mm Extension Cable

Description

330877-80-37-00 specifies a 3300 XL 50 mm extension cable configured with an 8.0 meter cable length, armored mechanical protection, and no agency approvals. This cable pairs with a 1.0 meter 3300 XL 50 mm proximity probe to establish a complete 9.0 meter transducer system with a compatible 3300 XL 50 mm Proximitor sensor. It is designed to transmit high-frequency eddy-current signals from the probe tip back to the sensor in demanding industrial rotating machinery environments.

This configuration incorporates Option 37, which wraps the perfluoroalkoxyethylene (PFA) insulated FluidLoc triaxial cable in a flexible stainless steel armor jacket. This design provides high mechanical resistance to abrasion and routing wear, contrasting with the unarmored Option 36. Additionally, because this unit carries Option 00 (No Approvals), it is specified for non-hazardous general industrial monitoring environments where certified explosion-proof or intrinsically safe ratings are not required.

Features

• 8.0 meter cable length (Option 80) for a total 9.0 meter system configuration when matched with a 1.0 meter probe.
• Flexible stainless steel armor with protective PFA outer jacket (Option 37) to prevent physical cable damage.
• FluidLoc coaxial cable structure with PFA insulation to prevent liquid migration along the cable interior.
• Standard miniature coaxial connectors featuring gold-plated brass and gold-plated beryllium copper contacts.
• Broad environmental operational limits from -51 degC to +200 degC (-60 degF to +392 degF).
• Minimum bend radius of 25.4 mm (1.0 inch) to support installation within restricted routing pathways.

Applications

• Shaft vibration and axial position measurement on large turbine rotors.
• Rotating machinery monitoring systems requiring very large target eddy-current displacement.
• Industrial steam turbine environments requiring resistance to high-temperature moisture ingress.
• General-purpose, non-hazardous area rotating machinery protection loops.

Installation Guidelines

• Ensure that the combined probe length and extension cable length equals the total system length designated by the Proximitor sensor (e.g., 1.0 m probe + 8.0 m extension cable = 9.0 m system).
• Do not exceed the minimum bend radius of 25.4 mm (1.0 inch) when routing the armored cable.
• Use the supplied connector protectors to keep the ClickLoc junctions free of moisture and contaminants.
• Avoid routing cables over sharp mechanical edges or in areas subject to continuous severe impacts.
