The Hydrostatic Level Transmitter features high-precision imported sensing chips with advanced temperature compensation and an integrated transmitter circuit, delivering a stable 4-20mA output for seamless integration with A/D acquisition systems. Built with high-quality imported components, it includes reverse polarity protection, bypass capacitor filtering, and electromagnetic shielding, ensuring strong resistance to EMI and RFI interference. Optional field display options enhance monitoring convenience.
This submersible level transmitter utilizes hydrostatic pressure measurement, where liquid static pressure is proportional to its height. A piezoresistive silicon or ceramic sensing element converts the pressure into an electrical signal, which undergoes temperature compensation and linear correction, resulting in an accurate 4-20mA DC output for reliable industrial liquid level measurement.
