WebA Platinum RTD uses platinum (Pt) for a resistance temperature sensing element, which has good temperature characteristics and is linear and stable. Among the various types of temperature sensors, Platinum RTDs have been used widely with their high accuracy. In particular, Pt100 (resistance value at 0° is 100 ohm) has been popular worldwide. WebThe RTD theory is a very frequently employed method of treating nonidealities in chemical reactors. Thus, we focus a little more on this theory in the next section and give its merits and demerits. In the same section, we also discuss the concept of mixing and give four commonly used mixing models from the literature. We dedicate the next section
