Configured for external eddy-current probe mounting and cable isolation in Bently Nevada TSI monitoring systems, the Bently Nevada 21000-16-05-00-076-04-02 (21000 Proximity Probe Housing Assembly) provides direct mechanical support and conduit-based cable routing. The assembly maintains probe positioning stability while isolating extension cable interfaces from contamination, oil ingress, and conductive debris inside rotating machinery environments.

Model Reference Notes

The supplied part number represents a fixed Bently Nevada 21000 Series housing configuration. The provided documentation does not include independent suffix decoding or field-selectable matrix segmentation.

Mechanical Specifications

Gap Voltage and Rotor Dynamics Considerations

The housing assembly maintains fixed mechanical positioning for eddy-current probe systems operating within shaft vibration and rotor displacement measurement loops. Probe target alignment directly influences scale factor consistency and waveform stability during rotor movement.

Gap voltage validation is typically performed during commissioning to verify probe linear operating range. Bently Nevada proximity systems commonly target DC bias values near -10 VDC depending on probe extension length and transducer calibration combinations.

Mechanical rigidity inside the housing assembly reduces positional drift generated by thermal casing expansion and vibration-induced movement. Proper conduit grounding and cable shielding practices assist in suppressing signal cross-talk between adjacent monitoring channels.

Technical Questions

Q: Does the housing assembly include an integrated proximitor sensor?
A: No. The assembly functions as a mechanical installation structure for externally connected probe and proximitor components.

Q: Can the housing be mounted directly on turbine bearing casings?
A: Yes. The assembly is designed for threaded installation on machinery casings supporting proximity probe measurement points.

Q: Why is probe gap adjustment required after installation?
A: Eddy-current probe output scaling depends on probe-to-target spacing and conductive target geometry.

Q: Does the assembly affect vibration signal quality?
A: Mechanical stability, grounding continuity, and cable routing practices influence low-level probe signal integrity.

Q: Are conduit grounding practices required during installation?
A: Yes. Shield continuity and single-point grounding practices should follow TSI installation procedures to reduce electrical noise coupling.

Field Installation Guidelines

• Verify threaded engagement depth before tightening the housing assembly.

• Maintain separation between probe cables and motor power conductors.

• Avoid excessive cable bending inside conduit routing sections.

• Confirm probe tip alignment before final locknut tightening.

• Inspect conduit sealing surfaces for contamination before installation.

• Use anti-static handling procedures during probe cable connection.

• Perform final gap voltage verification after mechanical tightening is completed.

• Maintain shield grounding continuity between the housing body and monitoring cabinet earth point.
