Differential transformer intake air pressure sensor

Differential pressure sensor is an open type magnetic mutual inductive sensorsSince a differential structure having two connected secondary winding , also known as a differential transmission. When the differential transformer primary coil is excited alternating power source , the secondary winding an induced electromotive force is generated . The secondary coils as the differential connection, the total output is the difference between the two coils induced electromotive force . When the core does not move when the total output of zero ; when the core moves , the output force varies linearly with the displacement of the core . Differential transformer intake Shaft Position Sensor detection and conversion process is: first pressure changes into the displacement of the transformer core , and then again by the differential transmission core displacement into an electrical signal output. This pressure Motor Sensors is mainly a vacuum diaphragm ( bellows ) , the differential transmission and other components. When the pressure changes , the bellows deformation differential transformer core drive movement , since the displacement of the core , the differential output of the transformer voltage is generated that is , this voltage is supplied to ECU after processing input. If the voltage level is determined in accordance with the time and make the injector spray job, you can determine the basic fuel injection quantity .
