Quick Detail

Description

The 21000-16-05-00-084-04-02 Proximity Probe Housing Assembly is engineered for precision vibration and position monitoring in industrial automation environments. Designed to accommodate the 3300 XL 8mm Proximity Probe, this assembly features a robust aluminum body with a 304 stainless steel sleeve, ensuring high durability and corrosion resistance in harsh industrial conditions. The housing supports a 0.5 m (20 in) probe cable and a penetration depth of 8.4 in, making it suitable for monitoring rotating machinery such as turbines, compressors, and pumps. Its 3/4-14 NPT threaded mounting and fittings allow secure and easy installation.

This assembly includes a dome cover, threaded conduit ports, O-rings, a reverse mount probe, thread seal, optional conduit fittings, and an optional standoff adapter, enabling flexible installation. The 21000 series is certified CSA Type 4 and is explosion-proof, compliant with hazardous area requirements and API 670 standards for externally mounted proximity probe housings. Sleeve length can be customized based on installation requirements, with additional support recommended for lengths exceeding 304 mm (12 inches) to reduce vibration. Optional probe supports and oil seals (part number 37948-01) are available for applications requiring inner bearing housing penetration.

This assembly ensures reliable signal transmission for condition monitoring, predictive maintenance, and industrial automation processes, providing consistent performance in high-temperature, high-vibration, and hazardous environments.

Applications

1. Turbine Shaft Monitoring
The 21000 housing assembly, combined with the 3300 XL 8mm probe, is ideal for turbine shaft vibration monitoring. Its penetration depth of 8.4 in allows accurate detection of rotor movement, helping prevent misalignment failures and reducing unscheduled downtime.

2. Compressor Condition Monitoring
Used in industrial compressors, the aluminum and stainless steel housing withstands elevated temperatures up to 177°C, ensuring reliable proximity measurements for rotor and bearing condition analysis.

3. Pump and Gearbox Vibration Analysis
The assembly enables continuous monitoring of pump and gearbox shafts in oil, gas, and chemical plants, providing early warning for imbalance, misalignment, or wear. The CSA Type 4 rating ensures explosion-proof operation in hazardous areas.

4. Predictive Maintenance in Power Plants
In power generation facilities, the 21000 series allows predictive maintenance by providing precise shaft position data for API 670-compliant monitoring systems, reducing maintenance costs and preventing catastrophic failures.

5. Industrial Automation Feedback Control
In automated manufacturing lines, the housing assembly supports high-resolution proximity probes, feeding real-time shaft position and vibration data to control systems, enabling adaptive process optimization and minimizing mechanical stress.
