Pressure sensor

Pressure sensors are used to detect the cylinder vacuum, atmospheric pressure , the boost ratio of the turbine engine , the cylinder pressure , oil pressure . Automotive pressure sensor applications have more capacitive, piezoresistive , differential transformer (LVDT), surface acoustic wave type (SAW). Capacitive pressure Crankshaft Position Sensor are used to detect negative pressure , hydraulic , pneumatic , measuring range 20 ~ 100kPa, with input high energy, dynamic response characteristics, environmental adaptability and other characteristics ; piezoresistive pressure sensor affected by temperature , the need separate temperature compensation circuit , but adapted for mass production ; LVDT pressure sensors have a greater output , easy digital output, but poor immunity ; SAW pressure sensor with a small size , light weight , low power consumption , high reliability, high sensitivity , high resolution, digital output , etc. , for automotive suction valve pressure detection can work stably at high temperature , is an ideal sensor .
