31000 and 32000 Proximity Probe Housing Assemblies

Datasheet

Bently Nevada Machinery Condition Monitoring



Description

The 31000/32000 Proximity Probe Housing Assemblies are recommended when mounting proximity probes through the machine case and are typically used for radially mounted transducers, whether vibration or Keyphasor measurements.

When using these housings to measure radial vibration, ensure that the machine casing is affixed to the bearing in order to get an accurate relative vibration signal.

When measuring shaft axial position with dual proximity probes, use housing 21022 instead. Consult datasheet (Document 141601).

Use of a Proximity probe housing allows external access to the proximity probe and its extension cable, permitting gap adjustment or probe replacement without disassembly of the machine. The 31000/32000 Proximity Probe Housing Assembly is made of polyphenylene sulfide (PPS), an advanced, highstrength, thermoplastic with excellent corrosion resistance. Other elements of the housing assembly are made of corrosion-resistant stainless steel. The housing can be ordered with installed 3300 XL Proximity Probes and a variety of conduit fittings.

141610 Rev. K

The 31000/32000 Proximity Probe Housing Assembly is fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.

When installed in conjunction with an approved transducer system and appropriate I.S. barriers, the 31000/32000 Proximity Probe Housing Assembly can be used in intrinsically safe hazardous area applications.

31000 and 32000 Proximity Probe Housing Assemblies Datasheet 141610 Rev. K

The 31000/32000 Housing is intended to provide mechanical and environmental protection only, and is not an explosionproof housing. When an explosion proof proximity probe housing assembly is required, use housing CA21000 or CA24701. Consult the datasheet (document 141600).

Hot Water and Steam Exposure Effects

leakage into surrounding areas. Bently Nevada, LLC, will not be held responsible for any damages resulting from leaking Proximity Probe Housing Assemblies. In addition, Proximity Probe Housing Assemblies and 3300 XL 8 mm proximity probes will not be replaced under the service plan due to probe leakage.

(Specification not guaranteed). Brief periods (up to one week) of contact with hot water (95°C [203°F]) and/or condensing steam should not significantly affect the strength of the plastic housing. Contact with these beyond this length of time may eventually cause the strength of the plastic housing to permanently decrease during the first 6 to 8 weeks of exposure, and then level at approximately half of its initial value. Tests of actual housing performance after contact with hot water and condensing steam have not been conducted.

Probe Pressure

The 31000/32000 Proximity Probe Housing Assembly is designed to seal differential pressure between the probe tip and the housing main body when used with a 3300 XL 8 mm probe. The sealing material internal to the probe case consists of a Viton O-ring; the Oring between the sleeve and the housing is a Neoprene O-ring. The plastic housing is certified to seal against hose-directed water according to NEMA 4X and IP66 standards but is not designed to resist internal or external pressure. Probes are not pressure tested prior to shipment. Contact our custom design department if you require a test of the pressure seal for your application.

It is the responsibility of the customer or user to ensure that all liquids and gases are contained and safely controlled should leakage occur from a Proximity Probe Housing Assembly. Solutions with high or low pH values may erode the tip

For desired probe penetration lengths of less than 25 mm (1.0 in), order a separate Individual Standoff Adapter.

The effective probe penetration length will then be reduced by the length of the Individual Standoff Adapter, plus an additional 13 mm (0.5 in) due to the NPT thread engagement.

Example:

To create a probe penetration length 13 mm (0.5in), order a 31000 housing with DDD (probe penetration) option of 030 [76 mm (3 in)] and a separate individual standoff adapter that is 51 mm (2.0 in) in length (part number 21003-020).

The standoff adapter covers 38 mm (2.0 in) of the probe sleeve plus an additional 13 mm (0.5 in).

Therefore, the effective probe penetration length drops to 13 mm (0.5 in).

If you use effective penetration lengths of less than 1.0 inches, signal effects are likely due to probe side view or rear view of metal components.
