| Abstract: | The paper discuss how to calculate series-parallel connection resistance which compensates the offset thermal drift, offset thermal drift coefficient and full measurement of pressure sensors. Jerhuofu equation comes from pressure sensors bridge circuit. The testing data from the bridge circuit is made to be a line by least square method. Then the slope of line is a condition to calculate resistance. Meeting the demands of compensation and applying, the series-parallel connection resistance through equations. |
