Abstract:
1. An oil pressure sensor comprising: a main body having an accommodation cavity therein, wherein an oil inlet pipe is extended downwards from said accommodation cavity; a separator provided in said accommodation cavity to cover said oil inlet pipe in order not to allow the oil pressure directly impact other component parts; an induction unit disposed on said separator with an induction element attached thereto and downwardly facing to said separator so as to detect the oil pressure; wherein a conduction medium is filled between said induction unit and said separator for assuring conduction of the oil pressure thereby upgrading a measurement sensibility of the oil pressure by said induction unit; a press board lay on said induction unit so as to enhance hermical effect of said induction unit thereby preventing oil leakage and improving accuracy of measurement; an electronic circuit formed on said press board with its circumference electrically in connection with said induction unit thereby actuating said induction unit and sending back measured data; and a lid covering said electronic circuit so as to enclose the lid along with said main body in a sealed state; wherein an opening is formed through said lid to bring lead wires of said electronic circuit to stretch out therefrom to another instrument for transmitting measured data.
