2.7.7.4. Sensor of absolute pressureThe sensor of absolute pressure is the strain gage measuring pressure in a receiver. In the sensor there is the metal diaphragm connected to a small wire. Change of pressure causes a diaphragm deflection, a tension of a wire and change of its electric resistance. The control unit submits the engine on the sensor tension 5 In and defines power failure size in the sensor. The sensor gives out a signal in the form of tension, and in process of pressure decrease power failure in the sensor increases. As the sensor of absolute pressure is used as the sensor of a consumption of air, its signal is one of important types of information which is used by EBU for regulation of supply of fuel and a corner of an advancing of ignition.
