Electronic Pressure Sensor 320-3063 for Cat C9 Engine Oil

Technical introduction

At present, there are two kinds of sensors used to monitor the engine oil pressure in automobiles according to their output signals: one is a sensor whose output is a continuous voltage signal, and the other is a sensor whose output is a continuous resistance signal plus a switch. These two kinds of sensors have high costs, and it is necessary for the automobile instrument to judge whether the engine oil pressure is normal or not by subsequent procedures.

Technical realization idea

This technology provides a sensor with one-way switch output, which has low cost, can directly connect an indicator light in series on the instrument to remind the driver whether the engine oil pressure is normal or not, and has the characteristics of exquisite product structure, long service life and good long-term working reliability. The technical solution of this technology is that an oil pressure sensor assembly is characterized by consisting of a shell assembly, a lower spring seat, a measuring spring and an end button assembly; Wherein, the shell assembly consists of a shell, a sealing gasket, a diaphragm, a pressure plate and a top core, wherein the sealing gasket, the diaphragm, the pressure plate and the top core are riveted and fixed in a shell cavity, the pressure plate is circular, the middle part of the pressure plate is recessed to one side, and a through hole is arranged on the recessed surface; one side of the top core contacts the diaphragm, and the other side of the top core passes through the through hole of the pressure plate; The end button assembly consists of an insert and an end button shell, wherein the insert is fixed in the end button shell, and the end button assembly is press-sealed on the shell assembly; The lower spring seat is installed on the top core through the central through hole; The measuring spring is located between the lower spring seat and the insert, and one side of the top core penetrates into the measuring spring. In the technical solution of this technology, the end button assembly is made of insert and engineering plastic PA6630%GF through injection molding.
