The HTS-LM03X series split-type liquid level transmitter is based on the principle that the static pressure of the measured liquid is proportional to the liquid height. The product uses the piezoresistive effect of diffused silicon sensitive element to convert static pressure into an electrical signal. Then, with the help of dedicated digital circuits, the signal is amplified, linearly compensated, anti-interference, surge protection and other signal processing to output an industrial standard signal.
