CA21000-34-05-00-036-03-02 Bently Nevada Explosion-Proof Proximity Probe Housing Assembly
Engineered as a heavy-duty, all-metal explosion-proof enclosure, the Bently Nevada CA21000-34-05-00-036-03-02 allows for external mounting and adjustment of proximity probes on critical industrial turbomachinery. It directly resolves the major operational pain point of machinery downtime during maintenance by enabling technicians to check, adjust, or replace sensors from outside the machine casing without a process shutdown. This assembly is specifically built for API 670-compliant vibration and position monitoring within hazardous, heavy-duty industrial zones such as oil refineries and chemical plants.
Expert Insights & Field Reliability
Engineer's Note:
"For the CA21000-34-05-00-036-03-02 assembly, our chief instrumentation engineer suggests verifying your internal casing clearance before installation. The 3.6-inch stainless steel sleeve provides excellent structural rigidity against heavy internal oil splash, but ensuring optimal orthogonal alignment to the target shaft during external mounting is critical to prevent eddy-current signal distortion."
Project Case:
"This specific 3.6-inch penetration explosion-proof model was successfully deployed in 2025 for a series of high-pressure multi-stage centrifugal pumps at an oil refinery in Texas. Operating under continuous thermal cycling and stringent Class I, Div 1 safety mandates, it has allowed field technicians to perform all routine sensor gap calibrations externally, saving the plant over 12 hours of maintenance downtime per cycle."
Custom Product FAQ
Q: Can the probe gap voltage of the CA21000-34-05-00-036-03-02 be adjusted while the machine is running?
A: Yes, the core benefit of this external housing is that it allows for safe, live adjustment. By unscrewing the heavy-duty metal dome cover, technicians can access the locking nuts and thread the probe sleeve in or out to set the correct gap voltage without shutting down the machinery.
Q: Does this specific configuration (-036) provide enough clearance for thick-walled machinery casings?
A: Yes, the "-036" option signifies a 3.6-inch (91 mm) sleeve penetration length. This extended depth is specifically engineered to reach through thick machine casings, insulation layers, and oil deflector shields, ensuring the probe tip positions perfectly near the shaft target.
Q: What installation advantages does the "-03" fitting option offer for field wiring?
A: The "-03" option includes a specialized cable seal grip with three distinct grommets, an NPT plug, and a reducer. This configuration ensures a liquid-tight, gas-proof conduit seal that matches the housing's CSA Type 4 rating, preventing moisture ingress and maintaining explosion-proof integrity.

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: Similar to the Americas, 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.
