Product Applications
Electrical Calibration (Gapping)
Features:
- Aluminum Probe Housing Assembly (21000)
- Stainless Steel Probe Housing Assembly (24701)
- Rated Explosion Proof for Hazardous Areas
- Backwards Compatible with Other Non-3300 XL Series Transducer System Components
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 21000-28-05-20-035-03-02 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).

Connect the probe lead to the Proximitor sensor using the 0.5-meter cable.Power the Proximitor system (typically -24V DC).Monitor the DC voltage output using a digital multimeter.Adjust the physical position of the probe sleeve until the multimeter reads the recommended center-gap voltage (typically -10.0 V DC for standard linear operational range).Once the voltage is stabilized at the target threshold, securely tighten the housing sleeve locknut to hold the probe firmly in position.
FAQs
-
What is the 21000-28-05-20-035-03-02？
+The Bently Nevada 21000 is a corrosion-resistant aluminum proximity probe housing assembly used to externally mount vibration sensors in industrial environments -
What are the main components of the 21000 assembly?
+It consists of a rugged aluminum body, a protective screw-on dome cover, threaded ports for conduit connections, a probe sleeve, O-rings, and an internal reverse-mount proximity probe -
Does the 21000 include hazardous area approvals by default?
+No. The housing itself serves as the mechanical enclosure, but the hazardous area certification depends on the specific proximity probe installed inside (such as the 3300 XL 8mm probe). -
What material is used for the probe sleeve?
+The probe sleeve is typically constructed from 304 stainless steel. For fully stainless steel applications rather than aluminum, Bently Nevada offers the sister 24701 Housing Assembly
