Abstract

PURPOSE:To make a pressure type scale small-sized and easy handling, by finding the value of an applied load through detecting the variation of inner pressure for the load. CONSTITUTION:A load receiving body 1 is tightly closed through permitting a side wall part 4 composed of a material having high softness and low elasticity to be provided at the peripheral part of an upper bottom part 2 and a lower bottom part 3 having high rigidity. A pressure detection part 8 composed of a pressure sensor e.g. consisting of Bourdon tube and a conversion part obtaining the value of the load and also, a display part 12, is connected with the part 4 via a pipe 7. On occasion of making the measurement of the load, prescribed amount of air is filled within the body 1 by an air pump 5 at first and indication of an indicator 19 is made zero by a zero button. The inner pressure of the body 1 is raised by applying the load and the pressure is converted into the value of the load and it is displayed 12. When the measurement is finished, an exhaust valve 6 is opened and the air within the body 1 is discharged.
