| titleOfInvention | Gas analysis device based on different altitudes |
| abstract | The invention discloses a gas analysis device based on different altitudes, which comprises a main control board, an oxygen sensor, an operational amplification circuit, a pressure sensor and a sulfur hexafluoride sensor. The invention can be self-adapted to working environments at different altitudes by arranging the pressure sensor without calibrating in other modes; according to the air pressure conditions at different altitudes, the working time of the air pump is adjusted by combining the working flow of the air pump at different air pressures, so that quantitative air is accurately extracted, and the precision, intelligence and stability of the whole system are improved; because the numerical value change of the air pressure sensor is larger in the air extraction process compared with the numerical value change in the air extraction process, the numerical value can also be used as an auxiliary tool to judge whether the system is in a normal working state. |
