The invention discloses an induct-type oil pressure detecting means. It could drive a mechanical component to product a displacement corresponding to the travel acting received and provide an induced signal corresponding to the displacement of an iron core in inductance coil. It then could display the measured value by circuit transforming and discriminating. The pressure sense element is a Bourdon Pipe in the first aspect of the invention, or a floating ball in the second aspect of the invention. So depending on moving position of the iron core in the inductance coil it could provide a corresponding induced signal from the characteristic relation between the iron core displacement and frequency, as to provide the value about being measured pressure or oil quantity from the signal changing by transforming the induced signal to corresponding signal of current, voltage or frequency through circuits.
