What is a liquid level sensor


Liquid level sensor (hydrostatic level gauge/liquid level transmitter/liquid level sensor/water level sensor) is a pressure sensor that measures liquid level. The static pressure input liquid level transmitter (liquid level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffusion silicon sensitive element or a ceramic capacitive pressure sensitive sensor to convert the static pressure into The electrical signal is converted into a standard electrical signal (usually 4~20mA/1~5VDC) through temperature compensation and linear correction, which is suitable for various systems and industries such as petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and so on.
