The RTD/Style 21 is a resistance temperature detector with a welded sheath and weatherproof terminal head, designed for ambient or process mounting. It features a 3-wire platinum 100-ohm sensing element with DIN 0.00385 alpha characteristics. Sheath diameters range from 1/8 inch to 3/8 inch, constructed from 316 stainless steel, with operating temperature ranges up to 788°C. The head is mounted directly to the sheath without an integrated process connection, and complementary compression fittings are available for external pipe attachment.
UE's Applied Sensor Technologies (AST) division designs and manufactures single and dual element RTDs, referencing IEC 751. Our expertise in product packaging, manufacturing techniques, and component sourcing allow us to provide you reliable, stable sensors with hardware and output flexibility, for general industrial and OEM use. Typical applications that utilize RTDs include lab equipment, heat tracing, commercial appliances, and water treatment skids.
