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.
