Capacitive level sensor CFS-1005U

liquidanalogfor industrial applications

This liquid level sensor uses the sensing capacitance of water to detect whether there is a liquid level. When there is no liquid level close to the sensor, due to the existence of distributed capacitance on the sensor, there is a certain static capacitance of the sensor to the ground. When the bit slowly rises close to the sensor, the parasitic capacitance of the liquid will couple to this static capacitance, making the final capacitance value of the sensor larger.The changed capacitance signal is then input to the control IC for signal conversion to change the changed electricity. The capacity is converted into a certain amount of change in electrical signals,and then a certain algorithm is used to detect and judge the degree of this change. When this change exceeds a certain threshold,it is considered that the liquid level reaches the sensing point FEATURE： 1. It can sense the change of the liquid surface without contacting the liquid 2 The sensing precision is high, it can be accurate to +3mm 3. The anti-interference is strong, and the long life is more than 200,000 times. container 4. It can sense liquids in non-metallic containers of different thicknesses and can sense containers upto 1 5mm thick APPLICATION： Can be widely used in water purifiers, soybean milk machines, industrial equipment, etc With water level controller
