31000-00-00-15-035-01-02 Bently Nevada Proximity Transducer Assembly For Low-clearance Or Thin-walled Machinery Casings
The Bently Nevada 31000-00-00-15-035-01-02 housing assembly features a specialized 3.5-inch penetration sleeve and an API 670-compliant, chemical-resistant PPS dome engineered specifically for low-clearance or thin-walled machinery casings. It eliminates the costly operational pain point of unexpected plant shutdowns by allowing maintenance technicians to safely adjust sensor gaps or hot-swap proximity probes externally while the machine is fully online. This compact configuration is the ideal choice for high-speed gearboxes, smaller centrifugal pumps, and tight bearing housings where avoiding internal physical contact with rotating shafts is critical.
Engineer's Note
"When retrofitting high-speed gearboxes or smaller process pumps, the 31000-00-00-15-035-01-02 is our default choice. Its shallow 3.5-inch penetration depth is specifically engineered for tight internal clearances. Using a standard 3.9-inch or 4.7-inch sleeve in these compact housings risks striking the internal shaft or oil deflectors during installation; this 3.5-inch model bypasses that risk entirely."
Project Case Study
Deployment Site: Marine Oil & Gas Offloading Platform (Deployed: 2025)
Application: Radial vibration tracking on compact, high-speed sea-water injection pumps.
Operational Environment: High salinity, persistent salt spray, and extreme high-frequency vibrations.
Performance Update: Operates continuously with zero structural failure. The heavy-duty PPS dome completely blocks corrosive salt fog from reaching the internal sensor, saving the asset team an estimated $45,000 annually in avoided moisture-related sensor faults and emergency tracking repairs.
Custom Product FAQ
Q: Why choose the 035 sleeve length over the 039 or 047 models?
A: The 035 indicates a shorter 3.5-inch penetration depth. You should select this model if your machine's casing wall is thin or if the internal clearance between the outer casing and the shaft is restricted, making the longer 3.9-inch or 4.7-inch models physically impossible to mount safely.
Q: Does this housing include explosion-proof certifications?
A: No, the 31000 series designates a non-explosion-proof assembly. For hazardous locations mandating ATEX/IECEx Zone 1 or Class I Div 1 approvals, you must source the 32000 series explosion-proof housing assemblies instead.
Q: Can the internal sensor be replaced while the pump or gearbox is running?
A: Yes. The assembly features an external seal arrangement. Maintenance personnel can safely unlock the housing cover, dial in the probe gap voltage, or completely replace a failed sensor without depressing machine oil loops or causing a facility shutdown.

Global Distribution Network
Amikon supplies industrial automation parts to more than 150 countries, covering a wide mix of regions.
The Americas, especially the USA and Canada, still rely quite a lot on replacement parts. Many sites there are older facilities like refineries or chemical plants.
Europe is similar, with countries such as Germany, UK, France and Italy. A lot of work there is about keeping existing systems running rather than new installations.
Asia-Pacific includes China, Japan, South Korea, Singapore and Australia. Industries there range from semiconductors to shipbuilding and mining, depending on the country.
Middle East and Africa, like UAE, Saudi Arabia, Qatar and South Africa, are more focused on energy-related operations, mainly oil, gas and power sectors.
