Quick Detail

Description

The 21000-16-05-00-030-04-02 Proximity Probe Housing Assembly is a robust aluminum enclosure specifically designed for externally mounting 3300 XL 8 mm proximity probes in industrial automation systems. Featuring a 0.5-meter (20-inch) probe cable, a 3/4-14 NPT mounting thread, and a 3.0-inch probe penetration, this assembly ensures precise and reliable measurement of rotating machinery vibration and shaft displacement. The housing is constructed from a durable aluminum body with a 304 stainless steel sleeve, providing excellent corrosion resistance and mechanical strength in harsh industrial environments.

The assembly includes a dome cover, threaded ports for conduit connections, O-rings, a reverse mount proximity probe, and optional standoff adapters and conduit fittings. Rated as CSA Type 4 explosion-proof enclosures, it meets the API 670 Standard for externally mounted proximity probe housings and supports intrinsically safe installations in hazardous areas. Sleeve length is adaptable to installation locations, and lengths exceeding 12 inches (304 mm) can be supported with optional Bently Nevada probe supports and oil seals (part number 37948-01) to minimize vibration and maintain measurement accuracy. The 21000 series housing is ideal for applications requiring reliable non-contact displacement monitoring in automated control systems and predictive maintenance solutions.

Applications

1. Turbomachinery Vibration Monitoring
Used in steam turbines, gas turbines, and compressors to monitor shaft displacement and vibration. The 3300 XL probe, combined with the 21000 housing, measures displacements up to 2 mm with 0.5% repeatability, ensuring early detection of imbalance, misalignment, or bearing wear in automated turbine monitoring systems.

2. Industrial Pump Shaft Position Measurement
Applied in centrifugal and axial pumps for real-time shaft position monitoring. The 3.0-inch probe penetration and stainless steel sleeve provide robust protection in corrosive and high-pressure environments. This ensures continuous, precise measurement critical for predictive maintenance schedules in chemical and petrochemical plants.

3. Gearbox and Mechanical Drive Monitoring
Proximity probe housings enable non-contact measurement of gearbox shafts in heavy-duty industrial drives. The 21000 housing supports long probe sleeves with optional sleeve support, maintaining measurement accuracy for shafts extending beyond 12 inches and reducing errors caused by vibration.

4. Hazardous Area Automation
The assembly is CSA-approved and explosion-proof, suitable for hazardous areas such as oil and gas facilities. It allows integration of intrinsically safe proximity probes to automated monitoring systems, enabling continuous vibration data collection without compromising safety.

5. Compact Machine Installations
In applications with space constraints, the housing assembly provides a reliable mounting solution while accommodating reverse mount probes and optional standoff adapters. Sleeve lengths can be customized to the machinery layout, maintaining optimal probe alignment and measurement integrity.
