Eddy-Current Displacement Scaling and Rotor Dynamics Interface

The Bently Nevada 24765-02-00 provides DC displacement measurement output for monitoring mechanical movement associated with turbine and rotating equipment case expansion. The transducer assembly converts physical expansion movement into a proportional electrical signal using a defined scale factor of 0.404 V/mm.

The measurement output can be evaluated together with TSI (Turbine Supervisory Instrumentation) parameters to analyze thermal growth behavior, rotor-to-case relationship changes, and mechanical position variations during machine operation.

The assembly configuration does not include spring return, requiring mechanical installation to maintain proper contact positioning and measurement alignment. Signal wiring practices should maintain separation from high-current conductors to minimize electrical interference affecting displacement measurement accuracy.

Frequently Asked Questions

Q: What is the measurement range of the 24765-02-00 transducer assembly?
A: The unit provides a linear measurement range of 50.8 mm (2.00 in) with a scale factor of 0.404 V/mm (10.25 V/in).

Q: Does the 24765-02-00 include a spring return mechanism?
A: No. The 24765-02-00 configuration uses the 00 spring option, which specifies operation without spring return.

Q: What type of signal output is provided by this assembly?
A: The assembly provides a DC proportional displacement signal output corresponding to measured case expansion movement.

Field Installation Guidelines

• Install the transducer assembly with mechanical alignment between the sensing element and the monitored case expansion movement point.
• Verify mounting rigidity to prevent mechanical looseness from introducing displacement measurement errors.
• Route signal cables separately from power cables, motor feeders, and high-voltage switching circuits.
• Use appropriate cable shielding and connect shields according to the plant grounding practice to reduce electromagnetic interference.
• Confirm the mechanical travel direction and zero reference position before commissioning.
• Validate the output signal response after installation by comparing physical movement with the electrical displacement output.
