Now aking ?????

really but i cant

Gill Sensors & Controls Thank you for quick reply Now I know why in my Peugeot 405 the fuel level gauge goes up and down while moving downhills and uphills respectively, the fuel level sensor located in the front of the tank Thank you very much 😊...

Good question! You ready for this? Inserting a dielectric between the electrodes does not increase the electric field, it actually weakens it and that's why there is an increase in capacitance: Here's how: * Capacitance (C) is directly proportional to the charge (Q) stored on the plates and inversely proportional to the voltage (V) across the plates (C = Q/V). * The voltage between the plates is related to the electric field (E) and the distance (d) between the plates by the equation V = E * d. * By weakening the electric field (E) for the same amount of charge (Q), the dielectric effectively reduces the voltage (V) needed to maintain that charge. * Since capacitance is inversely proportional to voltage, a decrease in voltage due to the dielectric leads to an increase in capacitance. Another way to think of it: Most dielectric materials are polarizable, meaning their internal charged particles (electrons and protons) can be slightly shifted by an external electric field. * When a voltage is applied to the capacitor plates, the electric field influences the polarizable molecules in the dielectric. * These molecules tend to align partially with the electric field, creating microscopic electric dipoles (tiny separations of positive and negative charges within the material, the micro-dipoles will have opposite polarity to the electric field because positive charges on the capacitor plates will tend to attract negative charges in the micro dipoles and viceversa). * The net effect of these microscopic dipoles is an additional electric field that opposes the original field from the capacitor plates. * This opposing field from the polarized dielectric weakens the overall electric field within the capacitor. * As explained earlier, a weaker electric field for the same charge translates to a higher capacitance. In essence, the dielectric acts like a helper, reducing the opposing force needed to store charge on the capacitor plates. This allows the capacitor to store more charge for the same voltage compared to a scenario with just air (dielectric constant of 1) as the separator.

No, just about closing the circuit with a minimal volt/amp to acertain its closing.

You can only use it with non-conducting liquid.

You can measure nitrogen liquid with a capacitance probe; nitrogen cannot conduct electricity because it has no free ions to carry the charge and it is not combustible which would make it suitable for this application.

***** thank you to answer me !! in our plant we use differential pressure technology to calculate level !!

***** is there any concerns when dealing with boiling water? I know the dielectric constant is likely to change due to density variation, and the wires connecting the circuit board must be thermally insulated; is there anything else I should be concerned with?

Mohamed Fahmy no , it should have two

Hamad Almutawa if you use the tank itself as the other part of the capacitor.

I think so. There is no association between capacitance change and frequency change.
