Abstract

PURPOSE: To give a stable temperature characteristic with a simple structure, by connecting a variable capacity and a reference capacity in series and by providing the operational amplifier, which can apply a constant voltage to one connection point, and a switch means switching at a fixed ratio.
CONSTITUTION: When switch means 16 is controlled according, to pulses, which are output from pulse generator 17 and have a fixed turning-on and off ratio, and has the short-circuit released, the same voltage as voltage VS of reference voltage source 15 is charged in reference capacitor CS, and voltage VC at point A becomes equal to voltage VS, and therefore, output voltage VO of operational amplifier 13 at this time becomes (1+CS/CX)VS, and the relation between the distance between fixed and moving electrodes for no pressure and movement quantity Δd of the moving electrode for pressure is expressed by CS/CX=1-Δd with the variable capacity value as CX, and VO=Δd.VS is obtained. As a result, the displacement converter of a stable temperature characteristic with a simple structure can be obtained.
