The main role of automotive sensor

Introduction The automotive  sensor is mainly used to detect cylinder negative pressure, atmospheric pressure, boost ratio of turbine engine, cylinder internal pressure, oil pressure, etc. The suction negative pressure sensor is mainly used for the detection of suction pressure, negative pressure and oil pressure. Automotive pressure sensors are more commonly used in capacitive, piezoresistive, differential transformer, and surface acoustic wave types. Capacitive pressure sensors are mainly used to detect negative pressure, hydraulic pressure, and air pressure. The measurement range is 20 ~ 100kPa. It has high input energy, good dynamic response characteristics, and good environmental adaptability.

Automotive sensors are greatly affected by temperature and require additional temperature compensation circuits, but are suitable for mass production; LVDT pressure sensors have large outputs and are easy to digitally output, but have poor interference resistance; SAW pressure sensors have small size and light weight , Low power consumption, high reliability, high sensitivity, high resolution, digital output and other characteristics, is used for automotive suction valve pressure detection, can work stably at high temperatures, is an ideal sensor.
