The 21000-16-05-00-050-04-02 is a core mechanical component in rotating machinery condition monitoring systems, specifically designed for the external mounting, protection, and fine-tuning of eddy current probes. The most significant feature of this configuration compared to previous models is its 5.0-inch (approximately 127mm) sleeve length, making it suitable for installation in thicker areas of the machine housing.
O-rings
A reverse mount proximity probe
A probe sleeve of optional length
The 21000, 24701, and 164818 Proximity Probe Housing Assemblies are available with Canadian Standards Association (CSA) approvals. They are rated explosion proof for hazardous areas. You can order hazardous area approved proximity probes with 21000 aluminum and 24701 stainless steel housings for intrinsically safe applications. Both housings are certified as CSA Type 4 enclosures and are fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.

Natural Gas
Providing rugged mechanical protection for units at remote unmanned stations against external physical damage.
Paper & Pulp
Protecting displacement sensor connectors from corrosion in high-temperature and humid environments.
Nuclear Power
Providing high-reliability, long-life sensor protection for critical auxiliary rotating equipment.
When using the 21000-16-05-00-050-04-02 housing, the priority is to ensure sealing reliability and physical length matching, verify that O-rings are intact and properly lubricated before installation to prevent oil leakage. Given its 5.0-inch long sleeve, it is essential to accurately check the mounting depth to ensure the internal reverse mount probe correctly reaches the target surface. Additionally, periodically inspect the mechanical tightness of the aluminum body and the cable seals to maintain its explosion-proof rating and environmental protection in hazardous areas.
It is an external proximity probe housing assembly manufactured by Bently Nevada, used for protecting and mounting proximity probes.
What is the primary function of the 21000-16-05-00-050-04-02?
It allows for the installation or replacement of internal probes from the outside without disassembling the machine casing.
How to use the 21000-16-05-00-050-04-02?
Install it on the machine's port, use a reverse-mount probe, and set the probe gap by adjusting the sleeve.
Is the 21000-16-05-00-050-04-02 waterproof?
Yes, when the cap is properly tightened, it provides environmental protection against rain ingress.
What precautions should be taken when maintaining 21000-16-05-00-050-04-02?
Periodically check the O-ring seals for aging and ensure all set screws are locked tight.
