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.
