The oxygen generator is mainly used by people who have difficulties in supplying oxygen to themselves, insufficient oxygen supply and need oxygen therapy. Due to the different circumstances of each person, the concentration requirements for oxygen supply are also different. The pressure of the adsorption tower in the oxygen generator is measured by the pressure sensor. When the pressure is greater, the more nitrogen is adsorbed, and the concentration of oxygen supply is also higher. In order to make corresponding adjustments according to the actual situation of the individual, ensure sufficient oxygen supply and avoid waste. In addition, the pressure sensor is used to monitor whether the patient has started to inhale, so as to avoid the waste of oxygen when not inhaling, effectively reduce the volume of the oxygen concentrator, and make it run more efficiently. At the same time, a smaller volume means lower power consumption and better portability.

   Sencoch launched the GZP160 MEMS pressure sensor, which has the characteristics of miniaturisation, high precision and cost-effectiveness, and has been successfully applied to the pressure measurement of domestic and foreign oxygen generators.
