QL float switch is a simple, safe and reliable liquid level controller. It uses one or more reed switches installed in a closed non-magnetic tube, and then passes this tube through one or more hollow float balls with ring magnets inside. The rise or fall of the liquid level will drive the float balls. Move together, so that the reed switch in the non-magnetically-conductive tube can attract or disconnect, and output a switching signal.
Small floating ball liquid level switch, light weight, simple working principle, high reliability, vertical or side installation, long working life, strong load shock resistance, widely used in drinking fountains, food machinery, water treatment, washing machine, hydraulic machine Inkjet printers, shipbuilding papermaking, printing, power generation equipment, dyes and other industries are also used for high and low level detection of industrial equipment in high temperature environments.
