Automotive Sensors - Pressure sensors are used to detect the cylinder negative pressure, atmospheric pressure, turbo boost ratio, the cylinder pressure, oil pressure. Intake negative pressure sensors are used to suction pressure, vacuum, hydraulic testing. Automotive pressure sensors more applications are capacitive, piezoresistive, differential transformer (LVDT), surface acoustic wave type (SAW). Capacitive pressure sensors are used to detect a negative pressure, hydraulic, pneumatic, measuring range 20 ~ 100kPa, automobile pressure sensor manufacturers, with input energy, good dynamic response, good environmental adaptability and other characteristics; piezoresistive pressure sensor of temperature greater impact, we need a separate temperature compensation circuitry, auto oil pressure sensor, but adapted to mass production; LVDT pressure sensor has a larger output, easy digital output, high-quality automotive pressure sensors, but poor immunity; SAW pressure sensor Small size, light weight, low power consumption, high reliability, high sensitivity, high resolution, digital output, etc., for automotive intake valve pressure detection, can operate stably at high temperatures, is an ideal sensor. Automotive sensors - gas concentration sensors are used to detect the vehicle body gas and exhaust emissions. Among them, the most important is the oxygen sensor, which detects the vehicle exhaust oxygen content, measured air-fuel ratio according to the concentration of oxygen in the exhaust gas, Shantou automotive pressure sensors, issued a feedback signal to the computer control means for controlling the air-fuel ratio to converge to the theoretical value . When the air-fuel ratio, increasing the concentration of oxygen in the exhaust gas oxygen sensor output voltage decreases; when the air-fuel ratio is low, reducing the oxygen concentration in the exhaust gas, the output voltage increases. The electronic control unit recognizes this mutation signal to the fuel injection amount is corrected so as to adjust the air-fuel ratio corresponding to near stoichiometric change.
