The Bently Nevada 32000-16-05-00-080-03-02, also cataloged as the 32000 Proximity Probe Housing, operates as a dedicated hardware component for the mechanical positioning and environmental protection of eddy-current proximity probes within machine casings.

Model Configuration Matrix

The 32000-16-05-00-080-03-02 part number specifies the housing geometry and interface requirements. The configuration denotes an 80 mm length, 1/2-20 UNF probe thread interface, and a 1/2-inch NPT mounting thread. This assembly provides the structural mounting required to align the probe tip accurately relative to the target, ensuring stable operation within mechanical monitoring environments.

Hardware Specifications

Mechanical Monitoring & Transducer Scaling

Accurate rotor dynamics monitoring depends on the mechanical stability of the housing assembly. The 32000 series allows for precise axial adjustment of the transducer tip to facilitate the -10 VDC gap voltage validation necessary for linear signal response. To maintain integrity, the housing must be rigidly secured to the machine casing using the included jam nut, preventing movement induced by shaft vibration. Cross-talk suppression should be maintained by ensuring adequate physical separation between multiple probe housings installed in close proximity.

Field Installation Guidelines

• Surface Preparation: Prepare the mounting boss with a hole tapped perpendicular to the target surface to prevent angular alignment deviations.

• Sealing: Utilize a thread sealant compatible with the operating environment on the NPT mounting threads to prevent casing fluid leakage.

• Adjustment: Thread the housing into the mounting boss and adjust until the probe tip is set to the required -10 VDC gap voltage.

• Lockdown: Tighten the jam nut to 5.1 N-m (45 in-lb) to secure the housing position against mechanical vibration.

Frequently Asked Questions

• Is this housing compatible with all Bently Nevada probes? The housing is designed for standard probe thread diameters (1/2-20 UNF); verify compatibility with specific probe models before installation.

• Can I replace the O-ring in the field? Yes, the O-ring is a consumable component and should be inspected during every maintenance outage for signs of degradation or wear.

• What is the purpose of the 80 mm length? This length provides the necessary reach to position the probe tip at the correct distance from the shaft in machines with thick casing walls.

• How do I prevent thread seizing? Use a compatible anti-seize compound on the threads if the housing is required to be removed periodically for inspection or calibration.

• Does this housing include the proximity probe? No, the 32000 series is a mechanical mounting assembly; the transducer probe and extension cable are sourced as separate components.

• Can the housing be used in high-vibration applications? Yes, the assembly is robust, but ensure the mounting boss is not subject to structural fatigue that could affect signal stability.

• What is the pressure rating of the housing? The seal integrity depends on the NPT installation; ensure the sealant is rated for the internal pressure of the machine casing.

• Why is perpendicular alignment critical? Any angular deviation from 90 degrees relative to the shaft surface creates non-linearities in the eddy-current probe output.
