FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the difference between the 21000-27-05-40-026-03-02 aluminum housing and the 24701 stainless steel version?
The 21000-27-05-40-026-03-02 features lightweight aluminum construction suitable for most industrial environments where weight is a concern, while the 24701 stainless steel version offers enhanced corrosion resistance for highly aggressive environments like offshore or chemical processing. Both carry identical CSA Type 4 and explosion-proof certifications and API 670 compliance. The 21000-27-05-40-026-03-02 with 4.0 in standoff adapter is ideal for installations requiring extended clearance without the added weight of stainless steel.
How to identify a reliable supplier for the 21000-27-05-40-026-03-02?
A reliable supplier should provide documented CSA certification traceability, verify the 4.0 in standoff adapter and 2.6 in penetration specifications, and demonstrate knowledge of hazardous area installation requirements. They must explain the API 670 compliance and provide genuine fitting kits with proper grommet sizes. Look for suppliers who can advise on matching the 21000-27-05-40-026-03-02 with appropriate intrinsically safe barriers and approved transducer systems. Avoid suppliers who cannot produce CSA documentation or lack understanding of explosion-proof installation practices.
What certifications are required when exporting the 21000-27-05-40-026-03-02 to the United States?
The 21000-27-05-40-026-03-02 carries CSA certification which is accepted in the US for hazardous locations through the CSA/US mutual recognition. Export documentation must include country of origin, product value declaration, and HTS classification. The CSA Type 4 and explosion-proof ratings satisfy NEC requirements for Class I hazardous areas when properly installed. No additional UL certification is required, though buyers should verify the complete transducer system and I.S. barriers carry appropriate US approvals for their specific area classification.
Why do probe housings fail in hazardous area installations while the 21000-27-05-40-026-03-02 survives?
Standard housings fail in hazardous areas due to improper sealing at cable entries, corrosion of fitting threads, and lack of certified explosion-proof construction. The 21000-27-05-40-026-03-02 survives with CSA certified explosion-proof design, included cable seal grip with correctly sized grommets preventing flame path compromise, and aluminum construction that resists corrosion while maintaining certification.
