The Bently Nevada 21000-16-10-00-040-03-02 is a robust proximity probe housing assembly built for reliable machine monitoring in hazardous environments. This unit accommodates the 3300 XL 8 mm probe and comes with a 1.0 metre (39-inch) probe cable. With a 4-inch probe penetration and 3/4-14 NPT mounting thread, this housing fits a wide range of turbomachinery applications.
The 21000-16-10-00-040-03-02 includes a probe option with connector for the 3300 XL 8 mm probe. Its cable length measures 1.0 metre, while the probe penetration reaches 4.0 inches (040 suffix). The mounting thread is 3/4-14 NPT, which is mandatory when no standoff adapter is selected. For fittings, this assembly supplies one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with three grommets for cable diameters from 1/8 to 3/8 inches.
The housing body uses lightweight aluminum, while the sleeve is constructed from AISI 304 stainless steel for added corrosion resistance. This combination offers a good balance of weight reduction and structural integrity. The unit weighs approximately 1.1 kg (2.4 lb) without fittings, and the maximum (C+D) dimension with a visible probe reaches 32.9 inches (83.5 cm).
This housing assembly holds CSA explosion-proof ratings for hazardous area installations. Additionally, it is certified as a CSA Type 4 enclosure, which ensures protection against falling dirt, rain, sleet, snow, and windblown dust. Furthermore, the Bently Nevada 21000 housing fully complies with the American Petroleum Institute's API 670 Standard for externally mounted proximity probe housings. This compliance makes it a trusted choice for the oil, gas, and petrochemical industries.
You can order this housing with hazardous area approved proximity probes for intrinsically safe applications. Both the 21000 aluminum housing and the 24701 stainless steel variant share the same certification standards.
The 21000-16-10-00-040-03-02 assembly consists of several key components: a dome cover that screws into the housing body, threaded ports for conduit connections, a probe sleeve of optional length, O-rings, a reverse mount proximity probe, and a thread seal. Optional conduit fittings and a standoff adapter are also available upon request.
The dome cover design simplifies access for probe installation and maintenance. Meanwhile, the threaded conduit ports provide flexible wiring options for different installation layouts. For applications requiring extra clearance or specific positioning, you can order the standoff adapter separately.
When installing this housing, apply the recommended torque to all threaded connections to maintain the explosion-proof seal. Use the appropriate grommet from the supplied set to match your cable diameter, which prevents cable damage and preserves the environmental seal. Additionally, ensure the 3/4-14 NPT thread is clean and coated with a suitable sealant before assembly.
For best results, mount the housing according to API 670 guidelines, keeping the probe tip perpendicular to the target surface. The reverse mount probe design allows flexible cable routing while maintaining stable probe positioning. Always verify the probe gap before final tightening.
