SPC600 series static capacitance level switch

The capacitive level switch determines the presence of media or air by detecting the dielectric constant of the medium. Based on the capacitance formed between the capacitive level switch and the medium (liquid or air) it is in. When the probe tip of the electrostatic capacitance level switch is immersed in a liquid, the capacitance changes greatly, and a change in the state of the switch is formed to achieve the purpose of indicating and controlling the liquid level.

Category

SPC660 capacitive level switch adopts the digital capacitance measurement method. The capacitive liquid level switch determines whether there is a medium or air by detecting the conductivity or insulation rate of the medium. Capacitance is formed between the level switch and the medium (liquid or air) it is in. When the probe tip of a capacitive level switch is immersed in liquid, the capacitance changes dramatically and the FET switch changes state. Capacitive level switches can operate in relatively clean, conductive, junction-free liquids. Including process water, hydrogen peroxide and other industrial fluids.
