Overview 
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 M5 circular sensor connector. The AMS 3012 are especially suitable for differential pressure measurement with large common-mode pressure. The transmitters with short circuit and reverse polarity protected output can be powered within a wide supply voltage range of 8 .. 36 V. All AMS 3012 are calibrated and temperature compensated in a range of -25 .. 85 °C and feature high accuracy at room temperature as well as a low overall error throughout the entire compensated temperature range. 


Available Pressure Ranges 
 Differential (relative) pressure: 0 .. 50 mbar up to 0 .. 10 bar
 Bidirectional differential pressure: -25 .. +25 mbar up to -1 .. +1 bar
 Absolut pressure: 0 .. 1 bar and 0 .. 2 bar
 Barometric pressure: 700 .. 1200 mbar
