The Bently Nevada 21000-00-00-15-085-03-02 is configured with Option A = 00 and Option B = 00, indicating that the housing assembly is supplied without a proximity probe and without a probe cable. This configuration provides maximum flexibility for users who already have compatible probes or who need to specify probe type separately.

The Bently Nevada 21000-00-00-15-085-03-02 incorporates a 1.5-inch (38 mm) standoff adapter (Option 15) together with an 8.5-inch (216 mm) probe penetration (Option 085). This arrangement positions the probe correctly through the machine casing while maintaining sufficient adjustment range for accurate shaft vibration and shaft position measurements. Probe penetration dimensions are specified in 0.1-inch increments throughout the 21000 Series ordering system.

The Bently Nevada 21000-00-00-15-085-03-02 is supplied with Option 03 conduit fittings, consisting of a cable seal grip and interchangeable grommets supporting cable diameters of 1/8–3/16 inch, 1/4–5/16 inch, and 5/16–3/8 inch.

Features:

  • Aluminum Probe Housing Assembly (21000)
  • Rated Explosion Proof for Hazardous Areas
  • CSA explosion-proof certification for hazardous areas
  • Flexible configuration with optional fittings
The Bently Nevada 21000-00-00-15-085-03-02 is an all-metal proximity probe housing assembly designed for externally mounting proximity probes in industrial rotating machinery applications. The 21000-00-00-15-085-03-02 consists of a dome cover that screws into the body of the housing, threaded ports for conduit connections, a probe sleeve, O-rings, a reverse mount proximity probe, a thread seal, and optional conduit fittings.

This housing assembly is constructed with a lightweight aluminum body and a 304 stainless steel sleeve, with a typical mass of 1.1 kg (2.4 lb) without fittings, making it an ideal choice for applications where both strength and weight are important considerations. The 21000-00-00-15-085-03-02 is designed for use with various Bently Nevada proximity probes, including 3300 XL 8mm, 3300 XL 11mm, and 3300 NSv probes

The 21000-00-00-15-085-03-02 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).

All prices are shown in USD.
The 21000-00-00-15-085-03-02 demonstrates excellent temperature adaptability, supporting an operating and storage temperature range of –51°C to +177°C (–60°F to +351°F) when used with 3300 XL 8mm or 11mm probes. For 3300 NSv probes, the operating range is –34°C to +177°C (–30°F to +351°F) with storage from –51°C to +177°C. The data sheet cautions that exposing 3300 XL or 3300 NSv probes to temperatures below –34°C (–30°F) may cause premature failure of their pressure seals. The sleeve length of the 21000-00-00-15-085-03-02 is determined by the installation location, and the probe lead must be longer than the sleeve. For sleeve lengths greater than 304 mm (12 inches), additional sleeve support is required to reduce vibration, and Bently Nevada offers probe support and oil seal solutions for such applications
  • Oil Refineries: Monitors catalytic cracking compressors and high-pressure pumps
  • Petrochemical Plants: Tracks rotor vibration and axial position in ethylene/ammonia production trains
  • Power Plants: Deployed on steam, gas, and hydro turbines to prevent shaft failures
  • Offshore Platforms: Protects injection/export compressors against ocean conditions and hazardous vapors
  • LNG Facilities: Safeguards cryogenic pumps and liquefaction compression trains

Conduit Port: Route the internal probe coaxial cable through the housing body to the threaded port outfitted with standard 3/4-14 NPT or reducer fittings (-03 option package).
Environmental Sealing: Secure the cable using the supplied cable seal grip and environmental grommets to protect against moisture or gases.
Proximitor Hookup: Link the reverse-mount probe connector inside the dome cavity to the standard extension cable leading out to your monitoring system Proximitor sensor, checking for a normal operational gap voltage output of roughly -9 V to -11 V DC.
