进气压力传感器

The pressure sensor Zhaofei20091732 Pressure sensor is the most common industrial practice of a sensor,and we usually use pressure sensors are made of piezoelectric effect,this sensor is also known as the piezoelectric senso。Inlet pressure sensor detects the throttle the rear of the intake manifold absolute pressure,which according to the size of engine speed and load testing the manifold absolute pressure changes,and then converted into a voltage signal sent to the electronic controller(ECU),ECU based on the size of the signal voltage to control the size of the basic fuel injection quantity。Bellows pressure sensor:the sensor has a flexible metal diaphragm seal,maintain the vacuum inside the external tube interlinked and vigor.When energetic pipe pressure changes,the film box or contraction or expansion,and promote the armature in the inductive line mobile,thus the voltage induced in the induction coil,this voltage signal to electronic control unit to control the fuel injection quantity.Location:the inlet pressure sensor installed in the inlet on.Role:automotive engine air filters test hole is blocked.It is based on the pressure difference across the filter test;if the pressure difference is zero,is not clogged;the contrary,the plug.
