    SW-10

    SW-10 water level sensor

    SW series water level sensor is a component designed for checking water level. According to the water level, the product sends oscillation frequency to the appliance’s control board. It depends on the pressure, magnetic field, and electric signal to realize the function.

    Environmental test 


    High temperature: put the product in(60±2)℃ for 168h, then back to normal temperature for 2h. After that, water level change of each gear is within ±15mm

    Low temperature: put the product in (-20℃±2℃)for 168h, then back to normal temperature for 2h. After that, water level change of each gear is within ±10mm


    Humidity resistance: put the product in (40℃±2℃, RH90%~95%)for 168h, then dry all water from the product, back to normal temperature for 2h. After that, water level change of each gear is within ±15mm  

    Durability test

    With rated voltage, alternatively test the highest water level and lowest water level, frequency 20 cycles/min, total 50,000 cycles.
