An RTD forms one arm of a Wheatstone bridge, as shown in Figure below.
An RTD forms one arm of a Wheatstone bridge, as shown in Figure below. The RTD in a balanced is used to measure a constant temperature, with the bridge operated mode. The RTD has a resistance of 25 V at a temperature of 0°C, and a thermal coefficient of resistance, α= 0.003925°C, The value of the variable resistance R1 must be set to 37 V to balance the bridge circuit.
(1) Determine the temperature of the RTD.
(2) Compare this circuit to the equal-arm bridge in Example 8.2. which circuit provides the greater static sensitivity?
