ABSTRACT:
A pressure sensor comprising a pressure-displacement translating mechanism including a movable body driven by a hydraulic pressure and a spring for urging the movable body in a direction opposite the pressure, and a displacement-pulse phase conversion unit including a permanent magnet secured to the movable body and a magnetically soft member carrying an electrical coil thereon and disposed at a stationary point adjacent to the region of movement of the permanent magnet. A pulse voltage is applied to one end of the electrical coil, the other end of which is connected in series with a resistor. A voltage drop across the resistor is detected, and a time lag of the voltage drop with respect to the pulse voltage, representing a measure of hydraulic pressure, is provided in the form of an analog voltage or a digital code.
