GENERAL DESCRIPTION
AMS 4712 is a series of miniaturized pressure
transmitters suitable for industrial applications and
high precision measurements. All AMS 4712 can
be powered within a supply voltage range of
VS = 8 .. 36 V and provide an industrial two-wire
4 .. 20 mA current loop output. They are calibrated
and temperature compensated in a wide
temperature range of -25 .. +85°C.
AMS 4712 comes in a robust plastic package and
is ready to use. Pressure is applied either via two
barbed side ports for differential (relative) or
bidirectional differential pressure transmitter types
or via a single port for absolute or barometric
types. The two-wire current loop output is
established using an M5 circular sensor connector.
AMS 4712’s package is dust- and water-tight
conforming to IP67.
The pressure transmitters in the AMS 4712 series
are available for various applications and pressure
ranges: Differential (relative) devices in pressure
ranges from 0 .. 5 mbar up to 0 .. 2 bar, absolute
pressure variants for 0 .. 1 bar 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 are available on request.
