Which is the best torque sensor brand - resistance strain dynamic torque sensor digital water pressure gauge

      The resistance strain dynamic torque sensor torque measurement uses strain electrical measurement technology. A resistance strain gauge is attached to the elastic shaft to form a measuring bridge. When the elastic shaft is slightly deformed by the torque, the resistance value of the bridge is changed, and the change of the strain bridge resistance is converted into a change of the electric signal to realize the torque measurement.
 
       The resistance strain type dynamic torque sensor is composed of an elastic shaft, a measuring bridge, an instrument amplifier, and an interface circuit. The elastic shaft is a sensitive component, and generates a large compressive stress and a tensile stress in the directions of 45 degrees and 135 degrees. The principal stress and the shear stress are equal. It is possible to use semiconductor resistance strain gauges and connect them into a differential full bridge whose output voltage is proportional to the torque received by the torsion shaft.
