Water Level Sensor Transmitter

The submersible liquid level transmitter is based on the principle that the hydrostatic pressure of the measured liquid level is proportional to the height of the liquid. It adopts the piezoresistive effect of diffusion silicon and converts the pressure into an electrical signal through a signal conditioning circuit, which is then converted into a standard current, voltage, and RS485 signal and output. The liquid level transmitter can be directly connected to PLC/DCS, display instruments, and computers, and can also be used for remote signal transmission. Liquid level transmitters are widely used in liquid level measurement in industries such as petrochemical, water supply and drainage, environmental protection, and power.
