ABSTRACT:
A novel oil pressure sensor includes component parts simply stacked up from bottom to top, namely a main body, a separator, an induction unit, a press board, an electronic circuit and a lid. The main body has an accommodation cavity to accommodate other component parts. An oil inlet pipe which extended downward from the accommodation cavity is covered by the separator to alleviate the impact of the flowing oil to the component parts. A conduction medium filled between the induction unit and the separator contributes to assuring conductance of the oil pressure thereby upgrading measurement sensitivity. The press board contributes to prevention of oil leakage. The electronic circuit sends the measured data to another instrument by simple and reliable plug and receptacle combination.
