3: Principle of static pressure measurement
When the sensor is put into a certain depth in the liquid to be measured, the formula for the pressure on the sensor's liquid surface is: P = ρ.g.H + Po
In the formula:
P: pressure on the liquid level gauge
ρ: measured liquid density
g: Gravitational acceleration (according to 9.8015 during commissioning)
Po: atmospheric pressure on the surface
H: Depth of the sensor into the liquid
At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through the gas-conducting stainless steel, and then the atmospheric pressure Po on the liquid surface is connected to the negative pressure chamber of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ. gH, obviously, by measuring the pressure P, the level depth can be obtained.
The input type liquid level transmitter uses a high-performance diffused silicon piezoresistive pressure sensor as a measurement element. After high-reliability amplifying processing circuits and precise temperature compensation, the gauge or absolute pressure of the measured medium is converted into a standard voltage. Or current signal. This product is small in size and easy to use and install. You can directly measure the liquid level from the end of the transmitter to the liquid level by directly putting it into the water.
