Quick Detail

Description

The 21000-00-00-00-00-02 Proximity Probe Housing Assembly provides a durable solution for externally mounting proximity probes in industrial automation systems. Constructed with an aluminum body and 304 stainless steel sleeve, the 21000-00-00-00-00-02 housing supports a minimum probe penetration of 1.0 in (25.4 mm) and a 3/4-14 NPT mounting thread. The assembly weighs approximately 1.1 kg (2.4 lb) without fittings and can be ordered with CSA approvals for hazardous area use.

The 21000-00-00-00-00-02 housing includes a screw-in dome cover, threaded conduit ports, O-rings, and a reverse mount probe sleeve. Sleeve lengths can be customized to match installation locations, with longer sleeves supported by optional Bently Nevada probe supports or oil seals (part number 37948-01) to reduce vibration. The 21000-00-00-00-00-02 housing fully complies with API 670 standards for externally mounted proximity probes and is suitable for intrinsically safe applications when paired with certified proximity probes. The lightweight yet robust design of the 21000-00-00-00-00-02 assembly ensures precise probe positioning for vibration, position, and speed measurements in industrial machinery.

Applications

Probe Installation on Turbomachinery
The 21000-00-00-00-00-02 enables precise external mounting of proximity probes on turbines, compressors, and pumps. Its aluminum body and 304 stainless steel sleeve provide high mechanical strength while keeping the weight at 1.1 kg (2.4 lb). The minimum probe penetration of 1.0 in (25.4 mm) ensures accurate vibration detection. Using the 21000-00-00-00-00-02, operators can install probes quickly with the 3/4-14 NPT mounting thread, reducing downtime.

Oil and Gas Equipment Monitoring
The 21000-00-00-00-00-02 housing is CSA-approved and rated explosion-proof, making it ideal for hazardous environments in refineries and chemical plants. With threaded conduit ports and optional conduit fittings, the 21000-00-00-00-00-02 allows secure electrical connections and supports intrinsically safe probe operation. The sleeve length can be customized to match equipment layout, ensuring reliable data collection without affecting probe performance.

Heavy Industrial Machinery Vibration Analysis
The 21000-00-00-00-00-02 is widely used for continuous vibration monitoring on motors, generators, and rotating shafts. Its aluminum body and stainless steel sleeve resist corrosion and mechanical wear. Sleeves longer than 304 mm (12 in) are supported with additional probe supports, minimizing vibration effects and maintaining data accuracy, making 21000-00-00-00-00-02 suitable for heavy-duty industrial environments.
