Description

The Bently Nevada 31000-00-00-15-039-01-02 is a 31000 Proximity Probe Housing Assembly designed to provide mechanical protection and a secure external mounting point for proximity probe installations through machine casings. This configuration is supplied without a proximity probe, probe cable, or standoff adapter, and includes a 3.9-inch probe penetration option, one M25 conduit fitting with two sealing plugs, and an M24 × 3 mounting thread. The assembly is typically used with radially mounted vibration probes and Keyphasor® transducers and is fully compliant with the requirements of API 670 for externally mounted proximity probe housings. When combined with an approved Bently Nevada transducer system and appropriate intrinsic safety barriers, it is also suitable for intrinsically safe hazardous-area installations. 

Frequently asked questions

Q:What conduit and mounting options are included?
A:This model is configured with one M25 conduit fitting and two sealing plugs (Option 01) together with an M24 × 3 mounting thread (Option 01) for metric installations.

Q:Is this housing suitable for hazardous-area installations?
A:Yes. When used with an approved Bently Nevada transducer system and the appropriate intrinsic safety barriers, it can be installed in intrinsically safe hazardous locations. The housing itself is intended for mechanical and environmental protection and is not an explosion-proof enclosure.

Q:Does this housing assembly include a proximity probe?

A:No. This configuration is supplied as a housing assembly only. The proximity probe, extension cable, and standoff adapter are not included and can be selected separately to match the application.

Application areas

• Chemical Processing – Used on agitators, compressors, pumps, and large electric motors where continuous shaft condition monitoring is required. The housing protects probe connections from industrial contaminants and mechanical damage.
• Mining and Mineral Processing – Suitable for heavy-duty pumps, compressors, crushers, and conveyor drive systems. It supports reliable proximity probe installation in demanding operating environments while improving service accessibility.
• Pulp and Paper Industry – Installed on paper machine drives, refiners, turbines, and process pumps to provide protected probe mounting for continuous vibration monitoring and equipment condition assessment.
• Water and Wastewater Facilities – Applied to high-capacity pumping stations and motor-driven equipment where shaft vibration and rotational reference signals are monitored to improve maintenance planning and equipment reliability.
