Description

The BENTLY NEVADA 21000-00-00-40-040-02-02 Proximity Probe Housing Assembly is to provide a robust external mounting and protective enclosure for a separately selected proximity probe used in rotating machinery condition monitoring. The 21000 Series housing assemblies are all-metal assemblies designed for external proximity probe installation and are used in applications such as shaft vibration and Keyphasor measurement.

The first -00 configuration indicates that the proximity probe is not included. The second -00 indicates that the probe cable is not required. Therefore, the 21000-00-00-40-040-02-02 is supplied as a housing configuration intended for use with a separately selected compatible Bently Nevada proximity probe and complete transducer system.

The -40 option specifies a 4.0 in / 102 mm standoff adapter. The -040 option specifies a 4.0 in / 102 mm probe penetration. These dimensions define the mechanical positioning of the probe relative to the housing and machine casing and should be matched carefully to the required probe installation depth. For long unsupported sleeve lengths, additional support may be required to reduce the possibility of mechanical resonance.

Features:

  • A dome cover that screws into the body of the housing
  • Threaded ports for conduit connections
  • A probe sleeve of optional length
  • A reverse mount proximity probe
The 21000, 24701, and 164818 Proximity Probe HousingAssemblies are available with Canadian StandardsAssociation (CSA) approvals. They are rated explosion prooffor hazardous areas.

The 21000-00-00-40-040-02-02 Bently Nevada Aluminum probe housing assembly may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
The 164818 Compact Proximity Probe Housing isalso available for applications with spacerestrictions. Ceramic capped probes areavailable with the 164818 housing.Sleeve length is determined by the location inwhich the probe and housing are installed. Theprobe lead must be longer than the sleeve.Sleeve lengths longer than 304 mm (12 inches)require additional sleeve support to reduce thevibration associated with unsupported longsleeve lengths.
  • Power Generation: Monitors turbine vibration, generators, and large cooling pumps continuously
  • Oil/Gas/Petrochemical: Tracks compressor health on rigs, refineries, and pipelines
  • Water/Wastewater: Connects seismic sensors to BOP machinery to prevent mechanical failures
  • Pulp/Paper/Heavy Manufacturing: Used in machinery diagnostics exposed to chemical washdowns or moisture

Thread Preparation: Apply approved thread sealant to the 3/4-14 NPT mounting thread (-02 designation).
Penetration Depth: Insert the probe sleeve matching your specified 4.0-inch penetration depth into the machine case port. 
Counterbore the machine case if side or rear-view clearances require it.
Sleeve Support: Ensure any total combined length under high-vibration conditions stays supported to prevent resonance.
Gap Adjustment: Thread the reverse-mount proximity probe inside the housing assembly to set the initial electrical gap externally without tearing down the machine.

Technical notes

The 21000 Series uses an aluminum housing assembly with a stainless-steel probe sleeve and includes a dome cover, threaded conduit ports, probe sleeve, O-rings, thread seal, and the selected fittings and standoff adapter. The housing family is designed for externally mounted proximity probe applications, is compliant with API 670 requirements, and is available in CSA-approved explosion-proof configurations for applicable hazardous-area installations.

FAQs

  • Does this specific part number include a sensor probe?

    +
    No, the -00-00 code prefix means you must supply or purchase the 8mm or 11mm proximity probe separately.
  • What certifications does the 21000 series carry?

    +
    The 21000 housing body complies fully with the API 670 Standard for vibration monitoring equipment. It holds CSA explosion-proof ratings for hazardous industrial environments.
  • Is this housing suitable for corrosive offshore applications?

    +
    No. The 21000 series uses an aluminum body, which is ideal for standard pump stations or conventional thermal power plants. For highly corrosive or offshore environments, the stainless steel 24701 series should be selected instead
