| Research Abstract |
A new type load cell was manufactured as an experiment. Two plates supported by four springs were used for electrodes of the load cell. The change in a weight placed on the load cell caused the change in the distance between two plates. Consequently, an electric capacitance between two plates changed. Thus, the weight could relate to the electric capacitance. The heating temperature was 120C-900C. Dependence of the electric capacitance on frequency of an alternating current and that on heating temperature were small in the range of 30kHz-100kHz. When the weight of a specimen decreased during drying, the electric capacitance decreased. In the initial stage of heating when the temperature was rising, the electric capacitance slightly changed, while strain of a traditional load cell remarkably changed.
