ULDY type capacitive level switchDetailed product description：

ULDY type capacitive level switch is a universal level switch. When the sensor is installed on the compartment, the probe and the compartment wall are respectively equivalent to the two plates of the capacitor; Due to the difference in dielectric constant between the tested material and air, a change in the level of the material in the warehouse will cause a change in the capacitance between the probe and the warehouse wall. When the capacitance is greater than the user's set value, the relay in the limit switch will activate and output a switch value to achieve the purpose of control (or alarm).
The principle and structural characteristics of capacitive level switches enable them to replace any basic level switch and are widely used in industries such as building materials, petroleum, chemical, light industry, metallurgy, etc. for upper and lower limit alarm and control of material and liquid levels.
