Configured for mechanical protection and transducer positioning in Turbine Supervisory Instrumentation (TSI) networks, the Bently Nevada 31000-26-05-00-100-03-02 (31000 Proximity Probe Housing Assemblies) provides direct physical execution. The hardware establishes an externally adjustable environmental seal that mounts directly to industrial machinery casings, allowing the variable depth placement of a 3300 series proximity probe relative to the observed target shaft without breaching the machinery enclosure.

Probe Scaling & Gap Voltage Validation

The mechanical infrastructure of the Bently Nevada 31000-26-05-00-100-03-02 housing enables fine-thread probe scaling adjustments directly in the field. When setting up the target proximity probe within the internal containment cylinder, engineers utilize an external dial metric or fractional system to control the probe tip gap relative to the target shaft. Precise positioning is confirmed via electrical gap voltage validation across the associated Proximitor loop. The installation technician monitors the calibration line to achieve a stable -10 VDC static target bias voltage. This steady-state bias sets the sensor at the exact midpoint of its linear eddy-current measurement range, supporting high-fidelity rotor dynamics tracking while contributing to cross-talk suppression among adjacent measurement axes.

Frequently Asked Questions

Q: Is a proximity probe or sensor core included under this specific model number?

A: No. This part number designates the mechanical housing, internal adjustment sleeves, and containment fittings only. The proximity probe and its companion Proximitor sensor must be procured as separate line items.

Q: Can the internal sleeve configuration be modified for different probe lengths?

A: The specific internal length and thread selection are determined by the fixed configuration code embedded within the suffix model matrix (such as the -100 sub-specifier). Field alterations are limited to the mechanical adjustments permitted by the external sleeve lock screws.

Field Installation Guidelines

NPT Conduit Engagement Limits: Threaded explosion-proof conduit entries must be fully engaged to maintain structural and sealing integrity. Follow regulatory guidelines requiring a minimum of 5 full threads engagement at all joint interfaces.
Shield Grounding Integrity: Route all internal proximity transducer cables cleanly through the housing cavity. The outer braided shield must remain ungrounded at the machine casing or housing side, extending completely back to the monitoring panel or proximity module ground bus.
Environmental Compression Seals: Prior to final locking, ensure that all internal o-ring configurations and cable packing glands are completely aligned. Uniformly tighten the housing sleeve nuts to prevent lubrication fluid bypass or vapor migration into the external junction fitting.
