Claims

[Scope of utility model registration request]

Around the load receiver that protrudes upward in the center,
Two load cell main bodies each having an even number of eight or more beams extending substantially radially are connected facing each other to form a load cell having a load receiving part and an installation side receiving part that protrude in the vertical direction, Moreover, strain gauges for elongation measurement and compression measurement are bonded to each of the even number of 8 or more beams, and the strain gauges are connected in series with strain gauges of the same type located symmetrically with respect to the center. The radial beam type load cell is characterized by being inserted into the crossroads of the bridge circuit, which is the measurement circuit.
