1st. Overview
The intelligent non-contact small tube liquid level sensor (hereinafter referred to as the small tube sensor) adopts
advanced signal processing technology and high-speed signal processing chip, which is specially designed for the liquid
level detection needs of infusion tubes and industrial small tubes. The intelligent non-contact small tube liquid level
sensor can output high and low level signals at the same time, which can meet the needs of various occasions.
The intelligent non-contact small tube liquid level sensor uses the sensing capacitance of water to detect whether there is
liquid. When there is no liquid approaching the sensor, the sensor has a certain static capacitance to the ground due to the
existence of distributed capacitance. , when the liquid level slowly rises and approaches the sensor, the parasitic
capacitance of the liquid will be coupled to this static capacitance, making the capacitance value of the sensor larger, and
the changed capacitance signal is then input to the control IC for signal conversion, which will change the The
capacitance is converted into the change of a certain electrical signal, and then a certain algorithm is used to detect and
judge the degree of this change. When the change exceeds a certain threshold, it is considered that the liquid level reaches
the sensing point.
2nd. Scope of application
It is specialized in small tube application industries, such as medical equipment, medical infusion, biological liquid
detection, scientific research and teaching equipment, intelligent coffee machine, intelligent water dispenser, intelligent
electrical appliances, industrial small tube liquid level detection, etc.
