Bently Nevada 330854-080-24-05 3300 XL 25 mm Extension Cable

Description

Option 080 (8.0 m length), Option 24 (High Temperature FluidLoc cable), and Option 05 (Multiple Approvals) define this specific configuration of the 330854-080-24-05 3300 XL 25 mm Extension Cable.

This triaxial cable is a component of the 3300 XL 25 mm Proximity Transducer System, connecting the 330851 proximity probe to the 330850 Proximitor Sensor. It features FluidLoc coaxial cable construction with a perfluoroalkoxyethylene (PFA) jacket, which prevents moisture and process fluids from migrating through the cable interior. Unlike the armored Option 25, this unarmored Option 24 configuration provides optimal flexibility for standard conduit and cable tray routing, maintaining electrical properties under continuous operating temperatures up to 200 degC. Option 05 adds multiple global hazardous area certifications, enabling installation in certified environments.

Features

• 8.0 Metre Length: Configured specifically for applications requiring an 8.0 m (26.2 ft) cable length, pairing with a 1.0 m probe to form a 9.0 m system.
• High Temperature FluidLoc Cable: Designed with a 75 ohm triaxial, PFA-insulated cable that seals against moisture entry and process fluid migration.
• ClickLoc Connectors: Fitted with gold-plated brass and gold-plated beryllium copper connectors for reliable connection and resistance to corrosion.
• High Temperature Performance: Supports continuous operation in temperatures ranging from -35 degC to +200 degC (-31 degF to +392 degF).
• Multiple Approvals: Certified for hazardous environments with multiple international approvals under Option 05 (including ATEX, IECEx, and North American standards).

Applications

This extension cable is used in the following industrial rotating machinery monitoring scenarios:

• Steam turbine thrust position and axial displacement monitoring
• Large-target shaft position measurements
• Rod-drop style applications in reciprocating compressors
• Power generation and oil & gas critical machinery protection systems

Installation Guidelines

Ensure optimal performance and durability of the transducer system by following these installation practices:

• System Length Matching: Confirm that the combined length of the proximity probe and this extension cable equals the required system length of the 3300 XL 25 mm Proximitor Sensor (e.g., a 1.0 m probe with this 8.0 m cable matches a 9.0 m Proximitor).
• Connector Protection: Always install the supplied connector protectors over the mated connections to keep out dirt, oil, and moisture. Do not use silicone tape inside the machine casing.
• Cable Bend Limits: Maintain a minimum bend radius of 25.4 mm (1.0 in) along the entire run to prevent shielding degradation or cable damage.
• Conduit Routing: Ensure the unarmored cable is routed through protective conduit or cable trays to prevent physical abrasion or mechanical damage in industrial environments.
• Torque Limits: Hand-tighten (finger tight) the ClickLoc connectors. If using tools, do not exceed the maximum torque limit of 0.565 N-m (5 in-lb).

Compliance and Certifications

The 330854-080-24-05 is certified under the Option 05 Multiple Approvals package. It meets the following safety and industrial standards:

• ATEX/IECEx: Intrinsic safety (Ex ia IIC T4/T5 Ga) and non-sparking/ec (Ex nA/ec IIC T4/T5 Gc) when installed per system instructions.
• North American (CNRTLUS): Class I, Zone 0, AEx/Ex ia IIC T4/T5 Ga; Class I, Division 2, Groups A, B, C, D hazardous location installations.
• CE Mark: Complies with European electromagnetic compatibility (EMC) standards.
