The EPC50 21000-28-05-00-130-04-02 is a Bently Nevada 21000 series proximity probe housing assembly. It provides mechanical protection and sealing for the 3300 XL 8mm proximity probe in harsh industrial environments. This component includes a 3300 XL 8mm probe and a 0.5-meter integral cable. The model number specifically represents the 21000 base type, explosion-proof certification, 0.5-meter cable length, no conduit adapter, a 13.0-inch insertion depth, and a specific thread configuration.
A reverse mount proximity probe
A probe sleeve of optional length
A dome cover that screws into the body of the housing
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.
