GENERAL DESCRIPTION

AMS 2712 is a series of compact OEM pressure sensor modules with 4 .. 20 mA current-loop output in various pressure ranges. The sensor modules are calibrated and temperature compensated and allow precise pressure measurements in a wide temperature range of -25 .. 85 °C.

With its large supply voltage range of 8 .. 36 V and the rugged, reverse polarity and short circuit protected current-loop output the AMS 2712 are especially suitable for applications in industrial environments.

AMS 2712 are compact pressure sensor modules, which can be easily integrated in other assemblies or used stand alone in a suitable package. Pressure is applied via metal pressure ports, the electrical connection can be done via solder pads, pin connectors or a PCB terminal block.

The pressure sensor modules in the AMS 2712 series are available for various ranges and types: Differential (relative) devices in pressure ranges from 0 .. 5 mbar up to 0 .. 2 bar, absolute pressure variants for 0 .. 1 and 0 .. 2 bar as well as a barometric type for 0.7 .. 1.2 bar. Bidirectional differential devices are available from -5 .. +5 mbar up to -1 .. +1 bar for measurement of positive and negative pressure differences. Other pressure ranges or modifications are available on request.
