German Parker liquid level sensor CPOM2DDV 60

German Parker liquid level sensor CPOM2DDV 60It is a common sensor for measuring liquid level position, which converts the height of the position into an electrical signal for output.

Working Principle:

Principle of static pressure measurement: When the liquid level transmitter is inserted into a certain depth of the measured liquid, the pressure formula on the sensor facing the liquid surface is: Ρ=ρ. g.H+Po, where:

P: Pressure exerted on the liquid level of the transmitter

ρ: Density of the tested liquid

g: Local gravity acceleration

Po: Atmospheric pressure on the liquid surface

H: Depth of liquid input into the transmitter

At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through gas guiding stainless steel, and 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 g. H. Obviously, by measuring the pressure P, the depth of the liquid level can be obtained.

German Parker liquid level sensor CPOM2DDV 60choose:

1. Consider the characteristics of the medium: the proportion of impurities in the liquid medium, whether it is prone to scaling, whether there is still alcohol, whether there is a chemical reaction when exposed to light, etc., to avoid affecting the measurement accuracy of the liquid level sensor during later use.

2. Consider the application environment, such as pressure, temperature, and liquid level range, in order to determine the selection range of the liquid level sensor;

3. Consider installation method: Install the opening position, diameter, standard, material, etc. of the liquid level sensor on the equipment process.
