Mode of operation The pressure sensors operate on the piezo-resistive measuring principle. The ceramic or stainless steel diaphram*) (thick-film hybrid technology) acquires the pressure through direct contact with the medium. The measurement is converted electronically into a linear output signal of DC 0...10 V or DC 4…20 mA.
