TMG4021 digital temperature switch

Working principle Electronic recording and conversion of input signals in industrial temperature measurement. Measure the resistance value of the platinum sensor at the end according to temperature changes, and electronically record this resistance value. The relationship between the measured resistance value and temperature is consistentIEC6 0751 International standards. Product Features ◆ Passive switch of relay controlled by microprocessor（SPDT）. ◆Platinum material temperature sensor has high long-term stability（Pt100, in accordance withIEC 60751Standard). ◆High measurement accuracy and short response time across the entire temperature range of the environment. ◆Specially designed for strictOEMDesigned for application. ◆The upper part of the shell can270°rotate
