Metallux pressure frequency-transducer ME703 is based on the ME550 capacitive cell with an additional hybrid electronic module for converting capacity variations into frequency variations, proportional to the pressure applied to the flush membrane when exposed to the media. The hybrid module is directly assembled on the opposite side of the ceramic sensor cell. The transducer is supplied with 6 wired interconnections: output frequency signal, frequency against reference capacity, frequency against measured capacity, temperature from built-in diode, ground and supply. Available pressure ranges are 60 mbar, 160 mbar, 400 mbar, 1-2-5-10-20 bar, absolute or gauge versions. Other ranges available on request.
