The utility model discloses can measure all resistance -type temperature detect wares to judge short circuit under the various line moulding formulas trouble of opening a way, various thermistor, potentiometer and foil gage and so on resistance measurement can also be applied to to this circuit. ...
One method to further improve the measurement accuracy is by adding an analog switch to the circuit. The ADC then measures the voltage (VX) at the output of the excitation signal and obtains a value for RWIRE1. By assuming RWIRE1 is approximately the same as RWIRE3, the RWIRE3 can be...
Using RTDs in a ratiometric measurement has the advantage in that it eliminates sources of error such as the accuracy and drift of the excitation current source. Below is a typical circuit for a 4-wire RTD ratiometric measurement circuit. The 4-wire configuration has the advantage that the ...
