As a member of the motorcycle digital speedometer Manufacturer, Yongchang is committed to the research of water level electrodes. There are many kinds of water level switches, and the electrode type water level switch is worth talking about.

  Principle of electrode type water level switch: The electrode type water level switch is composed of a primary electrode sensor and a secondary controller to form an integrated measuring system. The level switch is installed on the top of the container or on the wall of the container, and the electrode is inserted into the liquid. Take the single-electrode liquid supply type control as the column. During measurement, there is an AC signal voltage on the electrode. When the liquid level rises and touches the electrode, an AC signal current flows between the electrodes to generate a liquid level signal. After the control board receives the liquid level signal, it rectifies, filters, and amplifies Wait for processing, and finally converted into relay closed contact output or standard current 16mA output for users to use. When the liquid level drops and leaves the electrodes, there is no AC signal current flowing between the electrodes, the control board cannot receive the liquid level signal, the relay returns to the release state or the standard current returns to 8mA. Therefore, the liquid level can be accurately measured by whether the liquid is in contact with the electrode or not, the relay is closed or not, or the size of the current. Users can use relay contacts or output current to communicate with external equipment to realize automatic control of liquid level. The electrode type water level switch has a stronghold: if the electrode probe has scale, it is easy to malfunction or fail to operate.

The principle of the Water level electrode is a bit complicated, if you don’t understand it, you can first understand it in other ways.
