<p>The invention disclosed is a magnetic induction type pressure sensor comprising bourdon pipe, transmission mechanism and printed circuit board. The bourdon pipe could product a linear deformation proportionally pressure acting on it, to drive central rotation shaft through the transmission mechanism. There is a rotating dish on the shaft, with magnet provided for the outer edge. When the rotating dish relatively move to the printed circuit board the magnetic spring switch whereon could be inducted to close through magnetism of the magnetic in order to turn on the circuit by the magnetic spring switch. Displacement produced by the bourdon pipe, corresponding being measured pressure, could drive the rotating dish to pivot the central rotation shaft through the transmission mechanism, as to turn on the magnetic spring switch on the corresponding position to obtain the corresponding resistance value.</p> |
