The 21000-28-05-00-050-03-02 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.
A dome cover that screws into the body of the housing
A probe sleeve of optional length
Optional conduit fittings
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.The 164818 Compact Proximity Probe Housing is also available for applications with space restrictions. Ceramic capped probes are available with the 164818 housing.Sleeve length is determined by the location in which the probe and housing are 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.Bently Nevada offers a probe support and oil seal (part number 37948-01) for long sleeves that must go through an inner bearing housing. We also make custom sleeve supports.

Power Generation
Used to monitor shaft vibration and axial thrust. The 21000 series allows technicians to adjust or replace probes without opening the turbine casing.And monitoring the large fans and gearboxes that are often exposed to high humidity and weather.
Petrochemical & Refining
Used on synthesis gas units and ammonia compressors where precise gap adjustment of the probe is critical for safety.
Water & Wastewater Treatment
Used on large-scale intake and distribution pumps to detect bearing wear or shaft misalignment before a catastrophic failure occurs.
Oil & Gas
Monitoring centrifugal compressors and gas turbines at pipeline compressor stations.
Practical Reminder: Always check the mechanical drawings before installation. If the sleeve is too long, it may collide with the internal bearings or oil slinger ring; if it is too short, the probe cannot reach the shaft surface, resulting in no signal.Physical Protection: This 5-inch sleeve is made of 304 stainless steel, which is very robust and protects the delicate probe inside from being blown away by the high-temperature oil flow.Don't forget the "Extension Cable"The probe cable included with this model is only 0.5 meters (option -05).
What is the Bently Nevada 21000-28-05-00-050-03-02 ?
The Bently Nevada 21000-28-05-00-050-03-02 is a specific configuration of an Aluminum Proximity Probe Housing Assembly.
What is the difference between the 21000 and 24701 models?
The primary difference is the material: 21000 (Your model): Aluminum body with a 304 stainless steel sleeve. It is lighter (approx. 1.1 kg). 24701: Full stainless steel body and sleeve. It is heavier (approx. 1.8 kg) and used for more corrosive environments.
What is the temperature limit of 21000-28-05-00-050-03-02??
Standard Operating Temp: -51°C to +177°C (-60°F to +351°F). Note: If the environment drops below -34°C (-30°F), the pressure seals may become brittle and lose their effectiveness over time.
Whether 21000-28-05-00-050-03-02 is used in hazardous areas?
Yes. The 21000 series is rated explosion-proof and carries CSA approvals. It is designed to meet API 670 standards for externally mounted proximity probe housings. The "-28" probe option specifically denotes "multiple approvals," making it suitable for various global safety certifications.
Can I replace only the probe inside the 21000-28-05-00-050-03-02?
Yes. The assembly uses a "reverse mount" probe. If the probe fails, you can replace the probe itself (typically a 3300 XL 8 mm type) without replacing the entire aluminum housing, provided the housing and sleeve are undamaged.
