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.
