Technical Specifications Breakdown

Key parameters for the 21000-34-00-30-018-03-02 are listed below for quick reference:

Industry Applications

The aluminum body with 304 stainless steel sleeve provides corrosion resistance and structural integrity in petrochemical and power generation environments. The 1.8 in probe penetration and 3.0 in standoff adapter allow flexible positioning for accurate gap measurements. Engineers can rely on this assembly to maintain probe alignment and protect sensitive electronics from contamination.

Installation & Setup Guidance

When mounting the 21000-34-00-30-018-03-02, ensure the 3/4-14 NPT mounting thread is properly sealed to prevent ingress. The included fitting option provides a 3/4-14 NPT plug, a reducer to 1/2-14 NPT, and a cable seal grip with grommets for various cable diameters. Select the appropriate grommet size (1/8 to 3/16 in, 1/4 to 5/16 in, or 5/16 to 3/8 in) to match your cable. Tighten all connections to manufacturer torque specifications to maintain the CSA Type 4 enclosure rating. Verify that the probe sleeve length and standoff adapter are correctly positioned before finalizing the installation.

Maintenance & Reliability

Periodically inspect the housing assembly for signs of wear, corrosion, or loose fittings. Check the O-rings and thread seal for integrity to preserve the explosion-proof rating. The 304 stainless steel sleeve resists corrosion, but routine visual checks during scheduled outages help ensure long-term reliability. Replace any damaged grommets or seals promptly to maintain environmental protection.
