Information
- For a radial shaft measurement, the probe support must remain fixed to the bearing reference. Bently Nevada 31000-16-05-00-033-03-02 provides a sleeve-mounted sensing point and a protective enclosure around the cable junction.
Cable option: 0.5 m (20 in)
Standoff arrangement: None
Mechanical reach: 3.3 in (83.8 mm) nominal penetration
After the probe is set, secure the retaining nut and inspect the sealed openings. Treat enclosure protection and process leakage control as separate installation requirements.

Original housing datasheet excerpt
7-page manufacturer-original excerpt from 141610 Rev. R: housing construction, specifications, fittings and installation. Selected pages only; not the complete ordering tables. -
Installation preparation & verification
5-page Apter Power guide for 31000-16-05-00-033-03-02: model verification, penetration and cable checks, fitting inspection and commissioning preparation. Not a manufacturer-issued installation manual.
Platform applications: This assembly combines direct machine-case mounting with an accessible probe connection. Confirm the bearing reference, sensing target and cable route before installation.
-
Bearing-relative measurement
The probe position follows the casing reference, so secure the casing to the bearing before measuring relative shaft vibration. Match the complete sensing chain to the channel configuration. -
Compact direct mounting
The no-standoff arrangement places the housing at the outer sleeve. Check cover access, machine-case clearance and the required 3.3 in penetration before choosing the mounting location. -
Gap adjustment
The accessible probe sleeve permits adjustment from outside the machine. Set the operating gap from the actual probe response and target, then secure the retaining hardware. -
Cable entry management
Option 03 supports a sealed cable entry with a reducer and selectable grommets. Route the cable without strain at the connector and close the remaining housing openings.
Check the 3/4-14 NPT outer-sleeve connection, 3.3 in (83.8 mm) penetration and none standoff arrangement against the machine drawing.
Insert the probe sleeve and set the gap using the applicable probe procedure. The mechanical penetration value is not a target air-gap setting.
Fit the retainer under the retaining nut and tighten the nut to the recommended 29.4 N m. Keep the sleeve and probe position stable during tightening.
Fit the correct grommet and cable seal grip, then close unused openings. Tighten hole-plug nuts to 0.5 N m where they are used.
Control any leakage independently of the plastic enclosure. Sustained hot water or condensing steam can weaken PPS; assess seals and process conditions before operation.
Reconnect the matched cable chain, restore connector protection and fasten the cover. Check the final probe gap and channel response before the machine returns to service.

Technical notes
Installation relationship: The selected C plus D reach is 3.3 in. Use the machine drawing and probe gap-setting procedure to establish the installed position.
Protection: Type 4X and IP66 apply to the enclosure. This assembly is not an explosion-proof housing or a pressure vessel; any intrinsically safe installation requires the complete approved transducer arrangement.

FAQ View All FAQ
-
Does 31000-16-05-00-033-03-02 include a standoff adapter?No. Option 00 specifies no standoff adapter, so the housing mounts through the selected outer-sleeve arrangement. The final 02 option specifies a 3/4-14 NPT mounting thread.
-
What is the difference between the penetration and sensing gap on 31000-16-05-00-033-03-02?The 033 option sets a nominal 3.3 in probe penetration through the machine case. The sensing gap is the separate clearance between the probe tip and target, established during installation using the probe procedure.
-
How are the main structural parts of 31000-16-05-00-033-03-02 constructed?The housing is conductive, glass-reinforced PPS thermoplastic. The probe sleeve and retaining chain are AISI 304 stainless steel, while the outer sleeve and exterior screws are AISI 303 stainless steel.
-
Does IP66 make 31000-16-05-00-033-03-02 suitable as a pressure vessel?No. IP66 and Type 4X describe enclosure protection against the specified environmental exposure. The plastic housing is not designed to resist internal or external pressure, and the user must safely contain any leakage from the probe assembly.
-
Which tightening values apply when fitting 31000-16-05-00-033-03-02?The recommended retaining-nut torque is 29.4 N m (260 in-lb). If hole plugs are used, their nuts are tightened to 0.5 N m (5 in-lb). These are different fasteners and their torque values must not be interchanged.
-
Can long exposure to hot water affect 31000-16-05-00-033-03-02?Yes. Prolonged contact with hot water or condensing steam can permanently reduce the strength of the PPS housing. The probe temperature range alone does not establish suitability of the entire housing for sustained steam exposure.
-
How is the dispatch date confirmed for 31000-16-05-00-033-03-02?Provide the required quantity and destination with the enquiry. The sales team confirms availability, preparation time and the proposed dispatch date in the offer; the requested delivery date is not a shipment guarantee.
-
Which supplied items should be stated in an order for 31000-16-05-00-033-03-02?The order should identify the complete assembly, probe and cable, sleeve, fitting option 03 components and required documents. Request written confirmation of the actual included parts and unit condition before accepting the quotation.
