Abstract
A pressure sensor and sensing method, wherein the sensor comprises a pressure responsive element movable corresponding to a pressure to be measured and a means for detecting movement of the pressure responsive element. The movement detecting element comprises two parts of switch means movable to and fro with respect to each other, and a substantially constant oscillation is applied to one part so that movement of the pressure responsive element alters a threshold value which is applied to the substantially constant oscillation in order to produce a varying pulse signal.
