Description
The 21000-28-05-00-085-03-02 Proximity Probe Housing Assembly is designed for external mounting of 3300 XL 8mm probes, with selectable hazardous area approvals. It features a 0.5 m (20 in) probe cable, 8.5 in probe penetration, and an aluminum body with a 304 stainless steel sleeve, weighing 1.1 kg without fittings. Standard 3/414 NPT mounting threads, along with included NPT plug, reducer, and cable seal grips for 1/8–3/8 in cable diameters, allow straightforward integration into automated systems. The 21000-28-05-00-085-03-02 assembly includes a screw-in dome cover, threaded conduit ports, optional standoff adapter, and O-rings. It meets CSA Type 4 enclosure requirements and API 670 standards for externally mounted probe housings, supporting intrinsically safe applications. Sleeve lengths are customizable to site requirements; for sleeves over 12 in, additional support or oil seals (Bently Nevada part 37948-01) are recommended to reduce vibration. This 21000-28-05-00-085-03-02 Proximity Probe Housing Assembly enables rapid, secure installation of 3300 XL 8mm probes in hazardous or space-limited environments, maintaining consistent probe positioning for automated monitoring.
Applications
Measure Shaft Vibration in Turbomachinery
The 21000-28-05-00-085-03-02 Proximity Probe Housing Assembly supports 3300 XL 8mm probes to monitor radial vibration on fluid-film bearing machines. Its 8.5 in probe penetration and 0.5 m cable length allow precise positioning for large and medium turbines.
Monitor Axial Position on Compressors
Use the 21000-28-05-00-085-03-02 assembly to measure axial displacement on centrifugal and process gas compressors. The screw-in dome cover and aluminum body ensure secure mounting in tight spaces.
Install in Hazardous Areas
The 21000-28-05-00-085-03-02 assembly is CSA-approved and explosion-proof, allowing 3300 XL 8mm probes to operate safely in areas with flammable gases, meeting API 670 standards for externally mounted probe housings.
Support Keyphasor and Speed Measurements
This housing accommodates 3300 XL 8mm probes for Keyphasor and speed reference signals, enabling accurate rotational monitoring on pumps and generators.
