Quick Detail

Description

The 21000 Proximity Probe Housing Assembly is an industrial-grade solution designed for external mounting of proximity probes in critical automation systems. Constructed with a robust aluminum body and 304 stainless steel sleeve, this assembly ensures durability and resistance in demanding operational environments. The housing features a 3/4-14 NPT mounting thread, with no probe or cable required, and includes a dome cover, threaded conduit ports, O-rings, and optional standoff adapters. Typical mass is 1.1 kg (2.4 lb) without fittings, providing lightweight yet sturdy installation for machinery monitoring. The assembly supports sleeve lengths exceeding 304 mm (12 inches) with optional sleeve supports to reduce vibration, ensuring precise measurement in high-speed rotating equipment. Certified as CSA Type 4 and compliant with API 670 standards, the 21000 housing is suitable for hazardous area applications, offering an explosion-proof design compatible with intrinsically safe proximity probes. Ideal for automation systems requiring reliable shaft vibration or position detection, this housing integrates seamlessly into predictive maintenance frameworks and industrial monitoring setups.

Applications

1. Turbomachinery Monitoring
The 21000 housing can externally mount proximity probes on turbines, compressors, and generators. With sleeve lengths up to 12 inches, it enables accurate radial shaft vibration detection, critical for early fault detection in rotating machinery.

2. Pump and Motor Protection
When installed on industrial pumps or motors, the housing allows continuous monitoring of shaft displacement and vibration levels. Real-time data from the mounted probe aids in predictive maintenance and reduces unplanned downtime.

3. Oil & Gas Process Automation
The CSA-approved explosion-proof design enables safe deployment in hazardous areas, including refineries and petrochemical plants, complying with intrinsic safety standards for high-risk environments.

4. Compact Machinery Installations
Using the optional standoff adapter or the 164818 compact sleeve, the housing can fit constrained spaces without sacrificing measurement accuracy, enabling automation monitoring in compact pump or gear systems.

5. High-Speed Rotating Equipment Analysis
By providing stable support for long sleeves and vibration reduction with optional supports (part number 37948-01), the 21000 housing ensures reliable operation for rotors and shafts operating at high RPMs, enhancing overall operational safety.
