Configured for external probe mounting and mechanical cable routing in TSI vibration monitoring systems, the Bently Nevada 21000-16-05-00-135-03-02 (21000 Proximity Probe Housing Assembly) provides direct physical support for eddy-current probe installation, extension cable containment, and environmental sealing around rotating machinery measurement points.

Mechanical and Electrical Data

Eddy-Current Signal Stability

The housing assembly maintains fixed probe alignment relative to shaft targets and reduces mechanical displacement caused by conduit vibration or cable movement. Proper probe centering inside the housing body assists eddy-current scaling consistency during shaft vibration measurement.

Shield continuity between the probe cable and grounding structure should remain isolated from high-current motor grounding paths. Parallel routing with variable-frequency drive output cables should be avoided to reduce cross-talk coupling into the proximity transducer circuit.

For systems calibrated to standard Bently Nevada displacement characteristics, probe gap adjustment commonly targets approximately -10 VDC during installation verification procedures.

Technical Questions

Q: Does the housing assembly contain active electronic components?
A: No. The assembly is a passive mechanical structure intended for probe positioning, cable protection, and environmental isolation.

Q: Can the housing be installed with different probe system lengths?
A: The housing must match the specified probe and extension cable configuration defined for the transducer system calibration length.

Q: Is shield grounding required at both cable ends?
A: Single-point shield grounding is recommended to minimize ground loop noise within vibration monitoring circuits.

Q: Can conduit fittings be replaced in the field?
A: Thread-compatible conduit fittings may be exchanged if sealing integrity and mechanical retention are maintained.

Q: Does the housing influence probe linearity?
A: Incorrect probe centering, excessive vibration, or conductive contamination inside the housing can affect probe response stability.

Installation Practices

Before installation, verify probe thread compatibility and housing insertion depth against machine casing dimensions. Maintain adequate probe clearance to rotating surfaces during shaft thermal growth conditions.

Do not overtighten conduit fittings into the housing body. Excessive torque may distort sealing surfaces or alter probe alignment. Probe cables should remain separated from high-voltage conductors and switched inductive loads.

During final setup, confirm stable gap voltage readings before machinery startup. Cable bends near the housing outlet should maintain gradual routing without sharp compression points.
