Overview Manuals Technical notes Product Applications Installation Steps

Features:

  • Aluminum Probe Housing Assembly (21000)
  • Stainless Steel Probe Housing Assembly (24701)
  • Rated Explosion Proof for Hazardous Areas
The Bently-Nevada 21000 / 24701 Proximity Housing Assemblies are manufactured with Canadian Standards Association (CSA) approvals. They are rated explosion proof for hazardous areas.

Additionally, they can be manufactured with 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.

Sleeve length is determined by the location in which the probe and housing will be installed. The probe lead must be longer than the sleeve. Sleeve lengths longer than 304 mm (12 inches) require additional sleeve support to reduce the vibration associated with unsupported long sleeve lengths.

The 21000-28-05-00-050-03-02 Bently Nevada Proximity Probe HousingAssemblies may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
