Here we come to know about the main sensor on the car. Intake pressure sensor can measure the absolute pressure within the intake manifold, and converted into electrical signals and speed signals together into the computer according to the load state of the engine, as the basic decision injector fuel injection quantity basis. Widely used in the semiconductor piezoresistive pressure sensor intake. Throttle position sensor is mounted on the car throttle sensor for detecting the throttle opening. It is with the throttle linkage automotive sensor supplier via a lever mechanism, thus reflecting the different engine operating conditions. This sensor can be put in different engine operating conditions after the electronic control unit detects input (ECU), to control the fuel injection quantity different. It has three types: switch contact type throttle position sensor, linear variable resistive throttle position sensor, throttle position sensor integrated. Automotive Sensors - Pressure sensors are used to detect the cylinder vacuum, atmospheric pressure, turbo boost ratio engine, the cylinder pressure, oil pressure. Inspiratory negative pressure sensors are used to suction pressure, vacuum, hydraulic testing. Automotive pressure sensors more applications have capacitive, piezoresistive, differential transformer (LVDT), surface acoustic wave equation (SAW). Capacitive pressure sensors are used to detect negative pressure sensor, hydraulic, pneumatic car, the measurement range 20 ~ 100kPa, with input energy, good dynamic response characteristics, environmental adaptability and other characteristics; piezoresistive pressure sensor affected by temperature greater need for separate temperature compensation circuitry, but adapted to mass production; LVDT pressure sensor has a larger output, ease of digital output, but poor immunity; SAW pressure sensor is small, light weight, low power consumption, High reliability, high sensitivity, high resolution, digital output type and other characteristics of automotive sensors for automotive suction valve pressure detection, can stably operate at high temperatures, is an ideal sensor.
