TMG4022digitType 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 consistentIEC 60751International standards.

Product Features

lPassive switch of relay controlled by microprocessor（SPDT）.

lPlatinum material temperature sensor has high long-term stability(Pt100, in accordance withIEC 60751standard).

lHigh measurement accuracy and short response time across the entire temperature range of the environment.

Specially designed for demanding OEM applications.

lThe upper part of the shell can270°rotate
