The assembly features an aluminum body with a 304 stainless steel sleeve and a 3/4-14 NPT mounting thread. It is designed for use with selectable hazardous area approvals and is CSA certified as explosion-proof when ordered with appropriate options. This unit is supplied new in factory packaging with a 12-month warranty from AutoDCSTech.

Technical Specifications Breakdown

Key parameters for the 21000-34-00-15-030-04-02 are listed below for quick reference:

Industry Applications

The 1.5-inch standoff and 3.0-inch penetration accommodate standard probe positioning requirements. Its CSA Type 4 enclosure rating and compliance with API 670 Standard make it suitable for harsh industrial environments where reliability and safety are paramount. By choosing a pre-configured assembly like this, you reduce installation complexity and ensure consistent probe-to-target gap control.

Installation & Setup Guidance

Mount the assembly using the 3/4-14 NPT thread into a suitable conduit or housing port. Ensure the probe tip is clean and free of debris before insertion. The 1.0 m probe cable should be routed without sharp bends. For hazardous area installations, verify that the housing is used with the correct explosion-proof fittings (E:00, E:01, E:02, or E:04 options) to maintain CSA certification. Always follow the manufacturer's recommended torque values for the dome cover and fittings.

Maintenance & Reliability

Periodically inspect the housing for signs of corrosion or damage, especially in wet or corrosive environments. The aluminum body and stainless steel sleeve offer good resistance, but regular checks are advised. Verify that all O-rings and seals remain intact to maintain the enclosure rating. No internal adjustments are required; the assembly is designed for long-term, maintenance-free operation under normal conditions.

Compatibility & Integration

This assembly is designed for use with Bently Nevada 3300 XL 8 mm proximity probes. The 3/4-14 NPT mounting thread is a standard industrial connection, compatible with many conduit systems and mounting brackets. The assembly supports selectable hazardous area approvals, making it suitable for integration into safety-instrumented systems in refineries and chemical plants. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Selection Guide & Purchasing Advice

When selecting a proximity probe housing, consider the required standoff distance, probe penetration, and mounting thread. The 21000-34-00-15-030-04-02 configuration is optimized for applications needing a 1.5-inch standoff and 3.0-inch penetration with a 3/4-14 NPT connection.
