Body and its gas above.
The calculation formula of electric capacity is：C=εS/4πkd .Wherein, ε is a constant, and S is the facing area of capacitor plate, d
For the distance of capacitor plate, k is then electrostatic force constant.After installation is fixed, S and d are basically unchanged.Due to the permittivity ε of liquid
1 and liquid level on permittivity ε 2 it is different, such as：ε1>ε 2, then when liquid level raises, between the electrode of capacitance level gauge two always
Dielectric constant values increase thus capacitance increase therewith.Otherwise when liquid level declines, ε values reduce, and capacitance also reduces.So electricity
Appearance formula liquid level gauge can measure the height of liquid level by the change of two interelectrode capacitances.The sensitivity of capacitance liquid level meter is main
Depending on the difference of two kinds of dielectric constants, moreover, the constant of only ε 1 and ε 2 just can guarantee that level gauging is accurate, because of measured medium

Position measurement.But when measuring viscous medium, medium is easily adhered in measurement sensor capacitance level gauge, so as to cause electric capacity
Liquid level gauge measures misalignment, secondly, when capacitance level gauge is used to measure the pressure bulk container with stirring, due to the size of sensor
Longer, when stirring operation, stirring drives interior media disturbance, easily causes the different degrees of Bending Deformation of measurement sensor,
Fractureing for sensor even is caused, is this it is proposed that a kind of capacitance level gauge for measuring viscous medium rinses protection with suit
Put.
