Abstract: PURPOSE: A method for connecting a strain gauge is provided to output only a signal indicating the friction of a fixed liner without a lateral force and temperature change. CONSTITUTION: Strain gauges(R1-R8) installed on a gauge body are connected in the bridge shape. The second strain gauge is serially connected to the fifth strain gauge. The seventh strain gauge is serially connected with the sixth strain gauge. The first strain gauge is serially connected to the fourth strain gauge. The third strain gauge is serially connected to the eighth strain gauge. The second and fifth strain gauges and the seventh and sixth strain gauges are connected with a plus signal terminal(23). The first and fourth strain gauges and the third and eighth strain gauges are connected with a minus signal terminal(25). When a downward friction force is applied to a fixed liner, the gauge body is deformed. The tensile stress is applied to the first, fourth, sixth and seventh strain gauges. The compressive stress is applied to the second, third, fifth and eighth strain gauges. The resistances of the strain gauges applied with the tensile stress increases, while the resistances of the strain gauges applied with the compressive stress decreases. Then, voltage difference occurs between the plus terminal and the minus terminal. By using the voltage difference, the friction force of the fixed liner with a piston is obtained.
