Temperatur Messumformer

Temperature transducer: Main function and characteristics: Using the characteristic of the resistance value of platinum resistance (Cu) changing with temperature, transforming the temperature changes to the voltage changes, then by DC isolation transformation, obtains DC current and voltage output correspond to the output of the measured point temperature with which is completely isolated with input (temperature transducer). Adopts the three-line type platinum (Cu) resistance to measure electric circuit with automatic compensation function.
