Principle of liquid level switches
Shanghai Gaohe Imp. and Exp. Co.,Ltd | Updated: Jun 17, 2016

1. level switch – capacitive level switches

Capacitive level switch is used to detect liquid level changes caused by micro-capacitance (typically a PF) value changes, and managed by a dedicated ADA capacitance measurement signal processing chips, to detect the water level, and outputs the signal to the outputs. Capacitance type liquid level detection of maximum advantage can be detected through any medium containers of water or fluid changes.

2. liquid level switch – ball float liquid level switches

Ball float liquid level switch is to use micro switch contact output. When the path angle above the water level exceeds 28 °, ball float liquid level switch inside the ball will roll down to micro switch or from the micro switch, level switch contact signal output ON or OFF. Also have another kind of ball float liquid level switch, use the mercury switch contact output, contact when the liquid level rises when float, float weight-centered rise with water level angle. When the surface at more than 10 ° upward angle, level switch will contact signal output ON or OFF.
