Description
The31000/32000Proximity ProbeHousing Assemblies are recommended when mounting proximity probes through the machinecaseand aretypically used for radially mounted transducers, whether vibration or Keyphasor measurements.
When using thesehousings to measureradial vibration, ensurethat themachinecasing is affixed to thebearing in order to get an accuraterelative vibration signal.
When measuring shaft axialposition with dual proximity probes, usehousing 21022 instead. Consult datasheet (Document 141601).
Useofa Proximity probehousing allows externalaccess to theproximity probeand its extension cable, permitting gap adjustment or probereplacement without disassembly ofthe machine. The31000/32000Proximity ProbeHousing Assembly is madeofpolyphenylenesulfide(PPS), an advanced, highstrength, thermoplastic with excellent corrosion resistance. Other elements ofthehousing assembly aremadeof corrosion-resistant stainless steel. Thehousing can be ordered with installed 3300XL Proximity Probes and a variety ofconduit fittings.
The31000/32000Proximity ProbeHousing Assembly is fully compliant with theAmerican Petroleum Institute's (API) 670 Standard for externally mounted proximity probehousings.
When installed in conjunction with an approved transducer system and appropriateI.S. barriers, the31000/32000 Proximity ProbeHousing Assembly can beused in intrinsically safehazardous area applications.

The31000/32000Housing is intended to providemechanicaland environmental protection only, and is not an explosionproofhousing. When an explosion proof proximity probehousing assembly is required, usehousing CA21000or CA24701. Consult thedatasheet (document 141600).

Hot Water and Steam Exposure Effects
(Specification not guaranteed). Brief periods (up to oneweek) ofcontact with hot water (95°C[203°F]) and/or condensing steam should not significantly affect thestrength ofthe plastic housing. Contact with these beyond this length oftimemay eventually causethestrength ofthe plastic housing to permanently decreaseduring thefirst 6to 8weeks of exposure, and then levelat approximately halfofits initialvalue. Tests ofactualhousing performance after contact with hot water and condensing steam havenot been conducted.
Probe Pressure
The31000/32000Proximity ProbeHousing Assembly is designed to sealdifferential pressurebetween theprobetip and the housing main body when used with a 3300XL 8 mm probe. Thesealing materialinternalto the probecaseconsists ofa Viton O-ring; theOring between thesleeveand thehousing is a NeopreneO-ring. Theplastic housing is certified to sealagainst hose-directed water according to NEMA 4Xand IP66standards but is not designed to resist internalor externalpressure. Probes arenot pressuretested prior to shipment. Contact our custom design department ifyou requirea test ofthepressure sealfor your application.
It is theresponsibility ofthecustomer or user to ensurethat allliquids and gases arecontained and safely controlled should leakageoccur from a Proximity ProbeHousing Assembly. Solutions with high or low pHvalues may erodethetip
assembly oftheprobe, causing media leakageinto surrounding areas. Bently Nevada, LLC, willnot beheld responsible for any damages resulting from leaking Proximity ProbeHousing Assemblies. In addition, Proximity ProbeHousing Assemblies and 3300XL 8mm proximity probes willnot bereplaced under the serviceplan dueto probeleakage.
