Patent JP-S60133334-A (JP)
Title: Pressure sensor
Inventor: UEDA TOSHITSUGU
IPC: G01L13/06
Filed: 1983-12-22
Abstract: PURPOSE:To obtain a highly sensitive pressure sensor, which is hardly affected by the vibration noises and attitude change, by providing a force feedback means, which receives the displacement of a movable plate or a signal from a torque detecting means and imparts the force corresponding the signal to the movable plate. CONSTITUTION:Electrostatic capacity CX between electrodes 71 and 72, which are provided on the fixed plate 4 and a movable plate 62 is detected by an electrostatic-capacity measuring circuit 73, and a voltage eX corresponding to CX is outputted. An adder circuit 74 obtains the difference epsilon between the voltage signal eX from the electrostatic-capacity measuring circuit 73 and the voltage signal eX corresponding to initial capacity C0 (a state where pressures P1 and P2 are zero). The difference value is imparted to an amplifier 75. The amplifier 75 imparts the output to a coil 8, which is provided on the movable plate 62. The voltage corresponding to a current flowing the coil 8 is measured by a meter 77. Torque is generated in the movable plate 62 by the current flowing the coil 8. The torque is sent in the direction reverse to the direction of torque generated by the pressure difference between the pressures P1 and P2, i.e., the torque of the plate 62 is negatively fed back. Thus the movable plate 62 is balanced so that the input voltage epsilon of the amplifier 75 becomes zero. The pressure difference between P1 and P2 can be found as the displayed value on the meter 77. Thus the highly sensitive pressure sensor, which is hardly affected by vibration noises and attitude change can be obtained.
