A pressure sensor in the hydraulic system is a closed loop control to finish the main force. When the control valve is suddenly moved filter pressure annunciator offer, in a very short period of time will form a peak pressure in the system several times working pressure. In a typical mobile and industrial hydraulic filters in the pressure signal Wholesale, if not taken into account when designing such extreme conditions, and any pressure sensors will soon be destroyed. Need to use the impact of pressure sensors, pressure sensors to achieve impact in two main ways, one is to change the strain chips, another approach is to an external coil, generally use the first method filters the pressure in the hydraulic system Signal Supply, mainly because of easy installation. There is also a reason for the pressure sensor also under pressure from the hydraulic pump pulsation uninterrupted. Pressure sensors not only in the production of a wide range of measurement applications, now in our lives are often seen in most of our vehicles in both pressure sensors, most people know that there may be a pressure sensor on the car, in fact, a pressure sensor on an ordinary motorcycle applications. Powered motorcycle from oil combustion within the cylinder gasoline engine. Combustion power only to provide a good, good combustion gas mixture must have good, adequate and optimal compression ignition three conditions. EFI system can correct air-fuel ratio is controlled within the desired range, determine the merits of power, economy and emissions targets of the engine. The gasoline engine air-fuel ratio control is performed using the intake air amount and the fuel supply amount adjustment matched to achieve, therefore, the intake air flow measurement accuracy directly affects the air-fuel ratio control accuracy. Filter pressure annunciator production _ _ Xinfeng, Jiangxi filter pressure signal provided by the sensor Xinxiang City Xinfeng purification technology Limited.
