Description

The Bently Nevada 330876-02-50-00-00 operates as a dedicated hardware component for high-frequency eddy-current displacement sensing within 3300 XL 50 mm Proximity Transducer System platforms.

Hardware Specifications

Machinery Monitoring and TSI Characteristics

This hardware configuration directly drives exact eddy-current probe scaling within rotating machinery monitoring frameworks, specifically for measuring differential expansion on large steam turbine generators. The balanced 50 mm sensor core maintains precise structural and electrical tuning, which successfully eliminates cross-talk suppression failures when technicians route adjacent lines inside tight turbine enclosures. Furthermore, the internal impedance matching enables immediate gap voltage validation. Consequently, the assembly maintains stable targeting around calibrated -10 VDC operational centers and prevents signal attenuation that typically degrades the extended 0.394 V/mm scale factor required to evaluate rotor dynamics.

Frequently Asked Questions

Q: What structural parameters do the -02 and -50 option codes establish for this probe hardware?

A: The -02 option configures an M14x1.5 metric thread with a straight exit case profile, while the -50 code establishes a 5.0 meters (16.4 feet) total electrical and physical length for the integrated FluidLoc cable assembly.

Q: Can installation teams shorten the 5.0 meters integrated cable of the 330876-02-50-00-00 probe in the field?

A: No, cutting the cable is strictly prohibited. Trimming shifts the physical capacitance and resistance loop parameters, which corrupts the calibrated -10 VDC gap voltage validation and invalidates the TSI tracking loop.

Field Installation Guidelines

• Thread Engagement: Technicians must manually thread the M14x1.5 probe housing into the mounting bracket. Tighten strictly to standard torque limits using an open-ended wrench to prevent mechanical distortion of the internal coil element.
• Routing Radii: Always route the integrated FluidLoc probe cable with a minimum bend radius of 25.4 mm (1.0 in). Tight bends degrade the high-temperature shielding layer and introduce signal reflections into the measurement loop.
• Terminal Isolation: Wrap the ClickLoc coaxial junction with silicone tape or install standard connector protectors. This process blocks moisture ingress and prevents grounding loops caused by physical contact with the machine casing.
