Abstract
PURPOSE: To ensure the high-accuracy measurement over a wide range with emission of the calibration by providing the variable weight as well as the film destruction needle and thus performing the measurement by means of the theory of the beam balance.
CONSTITUTION: Film destruction needle is provided at the force point of beam 7, and weight 10 which shifts via motor 2, screw feed axle 3 and slide index component 4 each is provided at the load point. At the same time, index 4a which gives indication to the pressing force of needle 9 is provided to component 4 in opposition to scale plate 5. For measurement, weight 10 is shifted to the remote position from the close point to fulcrum 6 of beam 7, and thus needle 9 touches film 16 to be measured to increase the pressing force. And then film 16 broken by the pressure of needle 9. This breakage is detected by electric contacts 12 and 13 plus detection circuit 14, and thus the shift of weight 10 is stopped. Then the strength of film 16 can be obtained from the position of index 4a at the stop position.
