Description 4-20ma rs485 submersible fuel level pressure sensor
This series of input type liquid level transmitters are based on the principle that the measured liquid static pressure is proportional to the height of the liquid. The product uses the piezoresistive effect of ceramic sensitive elements to convert the static pressure into an electrical signal, and then cooperates with a dedicated digital circuit to pass the signal Amplification, linear compensation, anti-interference, anti-surge protection and other signal processing, an integrated product that outputs industry standard signals.
