What is the difference between the liquid level sensor and the pressure sensor?

Pressure sensors and level sensors are two sensors we often use, but few people know where they are in. Only the difference of the pressure sensor and the level sensor can better select the type you need. First, the measurement principle of the pressure sensor and the liquid level sensor is similar, and it is used to use the sensor to be put into a depth in the sub-liquid body. The pressure formula of the sensor is: ρ = ρ.g.h + PO: P is the pressure ρ of the liquid level gauge, is the pressure of the liquid density G is a gravity acceleration (according to 9.8015) PO It is that the atmospheric pressure h on the liquid surface is the depth of the sensor into the liquid, and the pressure of the liquid is introduced into the positive pressure chamber of the sensor by the air stainless steel, and then the atmospheric pressure Po on the liquid surface is connected to the back surface of the sensor to cancel the back surface of the sensor. PO, so that the sensor is measured: ρ.gh, it is clear that the liquid level is obtained by measuring the pressure P. However, the pressure sensor output is a pressure P, and the liquid level sensor outputs a depth H. Second, the pressure sensor is different from the classification of the liquid level sensor. Liquid level sensors are generally divided into float-type liquid level sensors, a floating cylindrical liquid level sensor, a static pressure level sensor, and a input liquid level sensor. Pressure sensors can generally be divided into strain chip pressure sensors, ceramic pressure sensors, diffusion silicon pressure sensors, and sapphire pressure sensors. FQJ, read full text
