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),
Wheatstone bridge
Bridge Circuit Construction
Figure 1 shows a basic bridge circuit which consists of three known resistances, R1, R2, and R3 (variable), an unknown
How RTD Measuring the Temperature
Measuring temperature with RTD / Resistance thermometer The RTD resistance will change with respect to the temperature. So temperature will be
