A torsional sensing load cell (100) comprises a load sensing member (60) having first and second deflecting portions (65, 67). 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 (60) which is detected by transducers (202, 204) 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.
