Quick Detail

Description

The 21000-28-05-35-028-00-02 Proximity Probe Housing Assembly is a precision-engineered solution for externally mounting 3300 XL 8 mm proximity probes in industrial automation systems. Featuring a robust aluminum body with a 304 stainless steel sleeve, this housing assembly is designed for use in hazardous areas, offering selectable CSA-approved proximity probes for intrinsically safe applications. With a probe cable length of 0.5 meters (20 inches), a standoff adapter of 3.5 inches, and probe penetration of 2.8 inches, the assembly provides secure, stable, and vibration-resistant installation for position and vibration measurement systems. The housing includes a dome cover, threaded ports for conduit connections, O-rings, a reverse-mount proximity probe, and a thread seal. Certified as a CSA Type 4 enclosure, the 21000 housing complies with API 670 standards, ensuring reliable operation in demanding industrial environments. Its versatile design accommodates optional standoff adapters and can be adapted for long sleeves with additional support, making it ideal for fluid-film bearing machines, turbines, and compressors where precise measurement and durability are critical.

Applications

High-Temperature Turbine Monitoring
The 21000 housing assembly protects 3300 XL 8 mm probes installed in turbines operating at high temperatures up to 177 °C, ensuring continuous measurement of rotor vibration and shaft displacement.

Hazardous Area Vibration Sensing
CSA-approved proximity probes within the 21000 housing enable safe operation in explosive environments while accurately monitoring vibration levels in chemical plants or petrochemical installations.

Axial Position and Differential Expansion Measurements
Used to mount probes on turbine or generator casings, the housing allows precise measurement of differential expansion between rotors and stators, critical for predictive maintenance and rotor health analysis.

Compact and Space-Constrained Installations
With optional standoff adapters and sleeves up to 304 mm, the housing can be installed in restricted areas, such as compact pumps or auxiliary machinery, without compromising probe alignment or signal integrity.

Upgrade and Retrofit of Existing Systems
The 21000 housing supports interchangeable 3300 XL probes and extension cables, allowing seamless upgrades from older Bently Nevada or other transducer systems without reconfiguring the monitoring system.

Specifications

Competitive Advantage

CSA and Hazardous Area Certification
