Abstract

The invention discloses a pressure sensor, comprising an outer shell (3), a screw cap (4), a taper thread (5), a metal wiring connector (1) and an insulation casing (2); a digital micro-processor is arranged in a pressure sensor (6); a program processing module is used to collect, process and output the pressure signals; a sensing element of the pressure sensor (6) is a pressure-sensing micro-chip; and the pressure-sensing micro-chip is connected with the digital micro-processor through a signal circuit. The invention also discloses a manufacturing method for the pressure sensor. Compared with the prior art, the pressure sensor has the advantages of high precision, high reliability, long service life, corrosion resistance, low cost and high cost performance and has no mechanical componentcontact.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and relates to a detection and alarm device on the automobile, more specifically, the invention relates to a pressure sensor. In addition, the invention also provides a manufacturing method of the pressure sensor. Background technique [0002] As the information source of the automotive electronic control system, the automotive sensor is a key component of the automotive electronic control system and one of the core contents of the research in the field of automotive electronic technology. Automotive sensors perform real-time and accurate measurement and control of various information such as temperature, pressure, position, rotational speed, acceleration, and vibration. The key to measure the control system level of modern limousine lies in the quality and level of its sensors. At present, nearly a hundred sensors are installed on an ordinary domestic family car, while the number ...
