AMS 3012 is a series of matchbox sized pressure transmitters with a 4 .. 20 mA current-loop output in a robust dust- and water-tight (IP67) metal package. The pressure ports are realized by two M5 female threads and the electrical connection by an M5 circular sensor connector. AMS 3012 is especially suitable for differential pressure measurement with large common-mode pressure. The transmitter with short circuit and reverse polarity protected output can be powered within a wide supply voltage range 8 .. 36 V.
