Accurate monitoring of liquid levels is crucial for ensuring safe operation and efficient production during the storage and processing of liquids. The electrode type liquid level switch, as an intelligent liquid level monitoring device, can sense real-time changes in liquid level and transmit status information through electrical signals. The Hongguang instrument will delve into the working principle, characteristics, advantages, and widespread application scenarios of electrode level switches.
1、 Working principle of electrode type liquid level switch
The electrode type liquid level switch uses the contact state between the electrode and the liquid to determine the level. It usually consists of two or more electrodes, with one electrode installed in the lower position of the liquid and the other electrode installed in the higher position. When the liquid level is higher than the low level electrode, the circuit closes and the electrode senses the conductivity of the liquid, resulting in conduction. When the liquid level is lower than the high-level electrode, the circuit is disconnected, and the liquid is no longer conductive and cannot conduct. By detecting the open and close state of the circuit, the electrode type liquid level switch can accurately determine the level of the liquid.
