High quality engine intake manifold absolute sensor

Product description

An electric injection engine that uses an intake sensor to detect intake volume is called a D-injection system (velocity density type). The intake manifold absolute pressure sensor detects the intake volume not directly like the intake flow sensor, but indirectly. At the same time, it is also affected by many factors, so there are many different places in the detection and maintenance of the intake flow sensor, and the fault has its particularity. The intake sensor detects absolute pressure on the intake manifold behind the section and valve. It detects changes in absolute pressure in the manifold based on engine speed and load, and then converts the signal voltage to an electronic controller (ECU). The ECU controls the basic injection amount according to the signal voltage. There are many kinds of intake sensors, such as varistor type and capacitance type. Varistor has the advantages of fast response time, high detection accuracy, small size and flexible installation, and has been widely used in D injection system. The working principle of varistor type air intake sensor. The strain resistors RR2, R3, and R4 form the Wheatstone bridge and are connected to the silicon diaphragm. Specializing in the manufacture of intake manifold absolute pressure sensor, common rail pressure sensor, engineering hydraulic sensor, injection molding machine special pressure transmitter, urea pressure sensor, brake pressure transmitter, etc.
