In a sense, pressure sensors can measure the pressure or weight of the liquid on the device. They can be considered passive sensors, not active sensors. Active sensors such as ultrasonic and radar sensors have active output for leveling. The measured signal.
However, one of the advantages of using a pressure transducer to measure water level is its non-contact property. Compared with mechanical and static methods, there is no need for too many parts to contact with the liquid, and the installation is more convenient. In addition, in terms of measurement principles, compared to similar non-contact measurement methods such as laser and ultrasonic, the pressure sensor monitoring principle relationship is simpler and linear, and it is more intuitive in data processing, analysis and processing. For example, in the water level and well depth of the tunnel rainwater well, the pressure sensor is a more effective water level sensor alarm device.
The above shows the advantages of the pressure sensor in water level monitoring and alarm introduced by Feejoy Technology (ShangHai) Co., Ltd. for you.
