Studies have shown that oil and gas evaporation emissions are the largest source of VOCs emitted by automobiles, and they are also the main source of pollutants such as smog and PM2.5 in cities. The United States adopted strict standards for motor vehicle emissions earlier, and China's "National Six" standard further improved the requirements for emission indicators, while the fuel steam pressure sensor and the matching carbon tank detachment pressure sensor became the priority choice. They can effectively control vehicle emissions and detect fuel tank leaks.
Among them, the fuel evaporation pressure sensor plays a crucial role in the whole fuel evaporation system. It is used to monitor the change of vacuum in the vehicle fuel evaporation system, convert the detected pressure value into the corresponding voltage value, and transmit this voltage signal to the ECU, so as to judge whether the system meets the standard. The specified fuel evaporation and leakage standards and the determination of whether there is a risk of oil and gas emissions according to the pressure value of the lumen.
GZP6182A is a finished product of calibrated fuel evaporation pressure sensor launched by Sencoch for the automobile market. The product is used to measure the pressure in the fuel pipe to ensure the normal operation of the EVAP system. The product uses an automotive-grade signal conditioning chip to calibrate and compensate the output of the MEMS core, and can convert the pressure signal from -3.75kPa to +1.25kPa into an analog output signal from 4.5V to 0.5V (the range and output can be customized), with fast response speed and reliability. With high performance and good stability, it is a cost-effective sensor product.
