HW4601 input level transmitter uses high-performance diffusion of silicon pressure sensor as a measurement element, it measures the hydrostatic pressure which is proportional to the depth of the liquid and Convert to standard current or voltage by signal processing circuit.
This transmitter is suitable for liquid level measurement in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage systems and other industries.
