Abstract

PURPOSE: To enable measurement of the force acting on a pressure-receiving plate by adopting a displacement feed back type servo mechanism wherein the pressure- receiving plate is kept constantly at a balance point by giving the driving current to a movable coil connected unitedly with the pressure-receiving plate which receives the blast pressure.
CONSTITUTION: The central part of the pressure-receiving plate 7 arranged in the frontage of a casing 10 is exposed to the blast pressure shown by an arrow, while its rear is opened to the reference pressure from a passage 11. In the central part of the above pressure-rceiving plate 7 is fixed monolithically a cylinderical movable coil 8 having a winding 4. In addition, a magnet 3 is arranged in such a manner that it forms a magnetic field crossing the winding of the coil 8. When the pressure- receiving plate 7 diverges from a balance point under the influence of the blast pressure, this divergence is detected by a detecting device composed of a small hole 9 made in the coil 8, a light-emitting diode 5 and a light-receiving diode 6 and, the driving current being given to the coil 8 from an electric circuit, the pressure-receiving plate 7 is returned to the balance point. Moreover, a signal proportional to the above divergence is obtained at both ends of a resistance RL at the voltage e0, whereby the force acting on the plate 7 is measured.
