Bently Nevada 31000-16-10-00-030-02-02 Probe Housing
A through-case PPS housing with a 1 m 3300 XL 8 mm probe, no standoff and a 3.0-inch penetration.
Product Profile
31000-16-10-00-030-02-02 is a Bently Nevada 31000 housing assembly configured for a 3300 XL 8 mm probe. It uses a 1.0 m probe cable, no standoff adapter, 3.0-inch penetration, two 3/4-14 NPT fittings with one plug and a 3/4-14 NPT mounting thread.
The through-case housing provides NEMA Type 4X / IP66 environmental protection when correctly assembled. Its PPS and stainless-steel construction protects the probe installation, but it does not create an explosion-proof enclosure or a rated process-pressure seal.

System Role
- Positions and protects an 8 mm proximity probe through the machine case.
- Provides defined conduit entries and external access for probe adjustment.
- Uses the no-standoff configuration where the 3.0-inch penetration alone establishes reach.
- Supports API 670-oriented installation practice without replacing machine sealing engineering.
Compatibility
- Pair the internal probe with the compatible 3300 XL 8 mm extension cable and Proximitor Sensor.
- Confirm the machine port and mounting interface are 3/4-14 NPT.
- Keep case-to-bearing relative motion in mind because the probe is referenced to the housing mount.
- Add a suitable pressure seal or isolation design if required by the machine casing.
Applications
- Through-case radial shaft vibration measurement.
- Axial-position installations where a 3.0-inch probe penetration is correct.
- Replacement of the same housing code during a planned outage with loop recalibration.
FAQ
What drawing review is needed before ordering 31000-16-10-00-030-02-02?
Verify the 3/4-14 NPT port, target location, 3.0-inch penetration, probe adjustment range and clearance for both conduit fittings.
Does 31000-16-10-00-030-02-02 require a separate pressure seal?
Yes whenever the machine case is a pressure boundary; the housing has no specified pressure-seal rating.
How can case-to-bearing movement affect a channel using 31000-16-10-00-030-02-02?
Because the probe mount references the case, structural movement between the case and bearing can appear in the measured relative displacement and should be evaluated.
Which loop parts must be checked with 31000-16-10-00-030-02-02?
Confirm the 8 mm probe lead, extension-cable length, Proximitor Sensor, monitor scale and target material as one calibrated system.
What is the acceptance sequence after installing 31000-16-10-00-030-02-02?
Set and record gap voltage, secure the retaining hardware, verify sealing and cable support, review slow-roll data, then test alarms before enabling trips.
