Description

The Bently Nevada 330877-080-36-00, also cataloged as the 330877 3300 XL 50 mm Extension Cable, operates as a dedicated hardware component for proximity probe signal transmission within 3300 XL 50 mm Proximity Transducer System platforms.

Hardware Specifications

Machinery Monitoring and TSI Characteristics

The extension cable link supports critical parameters for differential expansion or rotor expansion within high-velocity steam turbine generator configurations. It enforces stringent cross-talk suppression between parallel proximity sensor pathways to preserve the linear output metrics. The mechanical construction safeguards eddy-current probe scaling limits, allowing stable gap voltage validation targeting standard -10 VDC operational baselines across long-range measurement zones without rotor dynamics interference.

Frequently Asked Questions

Q: Can the 330877-080-36-00 cable be interchanged with standard 8 mm or 11 mm transducer system components?

A: No, the 3300 XL 50 mm system requires unique electrical parameters; mixing components across distinct systems alters the nominal impedance and invalidates the eddy-current probe scaling.

Q: What function does the FluidLoc option serve within this configuration?

A: The FluidLoc cable configuration includes an internal sealing matrix that acts as a physical barrier to block moisture, oil, or process fluids from migrating through the internal structure of the cable run into the probe tip.

Field Installation Guidelines

Ensure all high-temperature ClickLoc coaxial connectors are free from metallic dust, moisture, and hydrocarbons prior to final mating. Apply an approved self-fusing silicone wrap over all connector interfaces to provide a secure outer environmental barrier against steam or oil vapor entry. Route the cable through dedicated, grounded metal conduit, adhering to a minimum physical bend radius of 25.4 mm to prevent damage to the internal insulation layers. Connect the structural outer shield firmly at the single specified system common ground terminal to inhibit the formation of unwanted common-mode noise loops.
