To make it possible to measure pressure in high accuracy at a low cost by facilitating the processing of signals, shortening the processing time and decreasing the dissipation power of a processing circuit.
In a pressure detector, wherein a plurality of pressure sensors are constituted as a unitary body and the pressure measuring range broader than the pressure measuring range of one pressure sensor is provided, an average value 13 of the respective values of two pressure sensors L and H related to the pressure measuring ranges in a mutually overlapped pressure measuring range R is made to be an output signal 16. Thus, the effects of disturbances and the like are reduced to one half by the simple operation, and the detecting accuracy is improved.
