Abstract
A torsional sensing load cell comprises a load sensing member having first and second deflecting portions. Force-receiving areas are defined on upper and lower surfaces of the deflecting portions for bearing a load and its corresponding reactive force. This imposes a torque on the load sensing member which is detected by transducers positioned to detect torsional stress. The transducers are coupled in a bridge circuit and are placed such that the output signal of the circuit is insensitive to the location of an applied load.
