Technical field
Chemical production technical field is the utility model is related to, relates in particular to a kind of condenser type liquid for measuring viscous medium
Position meter rinses protection corollary apparatus.
Background technology
Capacitance level gauge is to measure the height of liquid level using the change of measurement electric capacity.It is a metal bar insertion
In liquid container, a pole of the metal bar as electric capacity, another pole of the chamber wall as electric capacity.Two interelectrode media are liquid
Body and its gas above.The calculation formula of electric capacity is：C=εS/4πkd.Wherein, ε is a constant, S be capacitor plate just
To area, d is the distance of capacitor plate, and k is then electrostatic force constant.After installation is fixed, S and d are basically unchanged.Due to Jie of liquid
Permittivity ε 2 on electric constant ε 1 and liquid level is different, such as：ε1>ε 2, then when liquid level raises, the electrode of capacitance level gauge two
Between total dielectric constant values increase thus capacitance increase therewith.Otherwise when liquid level declines, ε values reduce, and capacitance also reduces.Institute
So that capacitance level gauge can measure the height of liquid level by the change of two interelectrode capacitances.Capacitance liquid level meter it is sensitive
Degree depends primarily 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 quilt
It is conductive to survey medium, so metal bar electrode has insulating barrier covering.Capacitance liquid level meter small volume, easily realize teletransmission and
Regulation, suitable for the level gauging with corrosivity and the medium of high pressure.But capacitance level gauge is situated between when measuring viscous medium
Matter is easily adhered in measurement sensor, and so as to cause capacitance liquid level meter to measure misalignment, secondly, capacitance level gauge is used to measure
During with the pressure bulk container stirred, due to the longer dimension of sensor, when stirring operation, stirring drives interior media to disturb,
The different degrees of Bending Deformation of measurement sensor is easily caused, or even causes fractureing for sensor.
