Why we use Wheatstone bridge in RTD?
RTD measures the temperature in function of variations of its resistance. In order to make them work (4 wire RTD),
RTD measures the temperature in function of variations of its resistance. In order to make them work (4 wire RTD),
Figure 1 shows a basic bridge circuit which consists of three known resistances, R1, R2, and R3 (variable), an unknown
Measuring temperature with RTD / Resistance thermometer The RTD resistance will change with respect to the temperature. So temperature will be
