Description

The Bently Nevada 21500-00-12-10-02, also cataloged as the Bently Nevada 21500 Proximity Transducer Probe, operates as a dedicated hardware component for non-contact shaft displacement and dynamic vibration measurement within 7200 Series Proximity Transducer Systems. Configured as an eddy-current transducer assembly, the hardware tracks physical changes in gap distances between the 5 mm probe tip and rotating elements, generating proportional voltage fluctuations that feed directly into localized monitoring platforms without signal latency.

Suffix Breakdown & Model Matrix

Hardware Specifications

Machinery Monitoring and TSI Characteristics

The component executes precise eddy-current probe scaling to translate raw physical displacement metrics into standard analog voltages. The hardware internal coil assembly enables stable gap voltage validation (-10 VDC targets) within the center of the 1.0 mm linear operational window, allowing field engineers to confirm proper mechanical calibration. Mechanical design elements combined with strict shielding frameworks provide robust cross-talk suppression between proximal probe lines, ensuring consistent data isolation for multi-axis rotor dynamics evaluation.

Frequently Asked Questions

Q: Can this 5 mm proximity probe be disconnected while the tracking loop is powered?

A: Yes, field connections between the probe, extension cable, and the Proximitor can be altered while the matching rack remains online. Connected instrumentation channels must be put into bypass mode prior to disconnection to prevent accidental transient alert triggers.

Q: What are the target material requirements for optimal linear output?

A: The calibrated 200 mV/mil scale factor is verified using an AISI 4140 steel target surface. Deviations in target metallurgy alter the eddy-current footprint, requiring adjusted scaling calculations within the receiving monitor configuration software.

Field Installation Guidelines

1. Thread the probe into the mounting bracket or housing until the target distance yields the exact gap voltage validation target specified by system documentation.
2. Maintain strict route segregation by isolating the sensor coaxial lines from alternating current power cables by a minimum distance of 300 mm.
3. Apply a minimum of 5 full thread engagements when passing through threaded entries to ensure long-term mechanical stability.
4. Establish a single-point instrumentation ground framework by grounding the cable outer shield only at the Proximitor sensor housing dock.
