AMS 2712 is a series of universal, ready-to-mount pressure sensor modules with two-wire current-loop output (4 .. 20 mA) available in various pressure ranges and configurations for the electrical connection. With its large supply voltage range of 8 .. 36 V and rugged, reverse polarity and short circuit protected current output the OEM pressure sensor modules are especially suitable for industrial applications. Due to its extensive calibration and temperature compensation AMS 2712 allows precise pressure measurements in a wide temperature range of -25 .. 85 °C.
