Bently Nevada 31000-16-10-15-100-02-02 Probe Housing
A through-case housing with a 1 m 8 mm probe, 1.5-inch standoff, 10.0-inch penetration and dual conduit fittings.
Key Information
31000-16-10-15-100-02-02 is an English-dimension Bently Nevada 31000 proximity probe housing assembly. The full code combines a standard 3300 XL 8 mm probe, 1.0 m probe cable, 1.5-inch standoff adapter, 10.0-inch penetration, two 3/4-14 NPT fittings with one plug and a 3/4-14 NPT mounting thread.
The housing protects and positions the probe through the machine case. Its polyphenylene sulfide body and stainless-steel sleeve hardware provide environmental protection, but the assembly is not an explosion-proof enclosure and is not designed to resist internal or external process pressure.
Functions
- Positions a 3300 XL 8 mm probe at a controlled depth through the machine case.
- Provides external access for probe adjustment while shielding the probe lead and connector.
- Accepts two hardline-conduit entries through the supplied fitting arrangement.
- Uses the standoff to create clearance between the machine surface and housing body.
- Supports intrinsically safe applications only when the complete approved probe loop and associated apparatus are used.

Installation
- Verify the machine port, target location and 11.5-inch combined reach on the installation drawing before shutdown.
- Because the combined dimension remains below 12 inches, the catalog does not trigger its long-sleeve support rule; site vibration and bracket stiffness still require review.
- Use the conduit fittings only for the hardline or metal-tubing arrangement defined by the installation.
- Keep the probe label visible when practical and route the 1 m lead without sharp bends or axial tension.
- Set gap voltage, secure the retaining hardware and prove channel alarms after reassembly.
Lifecycle
- Inspect the PPS cover, grounding liner, sleeve, O-rings and conduit seals during outages.
- Treat hot-water or condensing-steam exposure as a material-life concern because prolonged exposure can reduce housing strength.
- Do not treat the housing as a pressure boundary; provide separately engineered containment where leakage is credible.
- Keep probe, extension cable, Proximitor Sensor and monitor scaling recorded as one calibrated channel.
FAQ
What machine drawing is needed before ordering 31000-16-10-15-100-02-02?
Provide the port thread, case thickness, target radius, bearing-to-case position, available housing clearance and desired probe-tip location so the complete reach can be checked.
Does 31000-16-10-15-100-02-02 need an added sleeve support?
The catalog mandates support only when standoff plus penetration exceeds 12 inches; this build is below that threshold, but unusual vibration or orientation may justify additional mechanical review.
Can 31000-16-10-15-100-02-02 serve as a pressure seal?
No. The housing protects the probe installation, while process containment and leak consequences must be handled by a separate engineered design.
Which companion parts must be identified with 31000-16-10-15-100-02-02?
Supply the extension-cable code, Proximitor Sensor system length, monitor channel scale and any intrinsic-safety barrier so the complete 8 mm loop can be matched.
What acceptance evidence should follow installation of 31000-16-10-15-100-02-02?
Record final insertion, retaining-nut torque, gap voltage, slow-roll runout, alarm checks and enclosure-seal inspection before enabling protection functions.
