When the liquid level rises or falls, the stainless steel magnetic float ball is driven to move up and down, and the float ball triggers the magnetic spring switch in the detection rod to send a signal. The measuring range is from 0 to 2.5 meters. ● Switch point can provide multi-point monitoring ● Reliable performance, good repeatability ● Long life, can be used for liquid level limit monitoring or continuous monitoring ● with normally open or normally closed output ● For corrosive media can choose different materials float ball and measuring rod ● Suitable for small and medium-sized tank level alarm, liquid level monitoring ● suitable for measuring water, Oil medium for density ≥0.55g/cm³ level measurement, mainly used in wastewater/water purification treatment, shipbuilding, generator equipment, petrochemical, food, electronics, dyeing and finishing chemistry, rubber and plastic, hydraulic machinery, chemical and pharmaceutical industries.
