Design and Performance Study of a Precise Temperature Control Module

In this study, an attempt has been made to describe the design and performance study of a precise temperature control module using the integrated circuit transducer. The transducer produces an output current proportional to absolute temperature. The device acts as a high impedance constant current generator. The highest thermal overshot has been recorded at the lower set point and the lowest at the higher. This designed module shows 1.53°C (average) thermal overshot and negligible undershot from the set point. This module can be used in any temperature-sensing application between 0 and 150°C in which conventional electrical temperature sensors are currently used.
