Core principle of non-contact capacitive liquid level sensor

Описание: The core principle of non-contact capacitive liquid level sensor is to use the "difference in dielectric constant between liquid and gas" to calculate the liquid level height by detecting the change in capacitance value between electrodes. When the liquid level rises, the medium dominated by gas between the electrodes is replaced by liquid, the dielectric constant increases, and the capacitance value increases accordingly. The sensor then converts the capacitance signal into liquid level data output. Its non-contact measurement does not require contact with liquids, can avoid pollution, and is compatible with non-metallic storage tanks such as plastic and glass. It is easy to install and can also provide real-time feedback on liquid level data, with broad market prospects for use!
