The MI platinum RTD is a high-accuracy temperature sensor based on the linear variation of platinum resistance with temperature. It consists of a stainless steel protection sheath, high-density magnesium oxide insulation filler and a platinum resistance sensing element, compacted into a non-detachable solid integral structure through integrated drawing. The product complies with international standard IEC 751 and domestic technical specifications such as JB/T 8622-1997, and can be directly matched with various indicating instruments, recorders, controllers and data acquisition systems to provide stable and reliable temperature input signals for industrial sites.
