Technical Specifications Breakdown

Key parameters for the 21000-16-05-15-062-03-02 are listed below for quick reference:

Installation Guidance for Optimal Performance

When installing the 21000-16-05-15-062-03-02, ensure the mounting thread (3/4-14 NPT) is properly sealed to maintain the explosion-proof rating. Use the supplied fittings: one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and the cable seal grip with appropriate grommets for your cable diameter (1/8 to 3/16 in, 1/4 to 5/16 in, or 5/16 to 3/8 in). The standoff adapter (1.5 in) positions the probe correctly relative to the target surface. Verify that the maximum (C) + (D) dimension does not exceed 13.5 in (34.3 mm) to avoid interference.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion, damage to the O-rings, or loose fittings. Ensure the cable seal grip remains tight to prevent moisture ingress. The 304 stainless steel sleeve and aluminum body are designed for long-term service, but environmental factors such as chemical exposure may require more frequent checks. Always follow the manufacturer's guidelines for maintenance intervals.

Are you struggling with reliable vibration monitoring in hazardous environments?

For critical rotating machinery, accurate proximity probe measurements are essential for predictive maintenance and asset protection. The Bently Nevada 21000-16-05-15-062-03-02 proximity probe housing assembly provides a robust, explosion-proof enclosure designed to meet API 670 standards for externally mounted proximity probes. This assembly integrates a 3300 XL 8 mm probe with a 0.5 m cable, a 1.5-inch standoff adapter, and a 6.2-inch probe penetration, ensuring precise and stable readings in demanding industrial settings.

Robust Construction for Harsh Environments

The housing features an aluminum body with a 304 stainless steel sleeve, providing corrosion resistance and mechanical integrity. The assembly includes a dome cover, threaded ports for conduit connections, a probe sleeve of optional length, O-rings, a reverse mount proximity probe, a thread seal, and optional conduit fittings. This design ensures reliable operation in environments where moisture, dust, and vibration are present.

Hazardous Area Certification and Safety Compliance

This proximity probe housing assembly is available with Canadian Standards Association (CSA) approvals and is rated explosion proof for hazardous areas. The 21000 aluminum housing is certified as a CSA Type 4 enclosure, fully compliant with the American Petroleum Institute's API 670 Standard for externally mounted proximity probe housings. For intrinsically safe applications, hazardous area approved proximity probes can be ordered with this housing.

Selection Guide and Purchasing Advice

When selecting a proximity probe housing assembly, consider the probe type, cable length, standoff adapter, and penetration depth to match your machine's geometry. The 21000-16-05-15-062-03-02 is configured with a 3300 XL 8 mm probe, 0.5 m cable, 1.5 in standoff, and 6.2 in penetration, making it suitable for many standard turbine and compressor applications. AutoDCSTech offers this assembly as new and original in factory packing with a 12-month warranty. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
