AMS 2712 – analog pressure sensor module with 4-20 mA output

AMS 2712 – pressure module with current output 4-20 mA

Electrical connection of the AMS 2712

The AMS 2712 sensor is part of a series of miniaturized analog pressure transmitters* ready for use. AMS 2712 is a pressure sensor module* which fits for absolute, differential, gage and bidirectional differential pressure measurement.

One process of AMS 2712 production is the calibration as well as the compensation of temperature dependent drift of offset and span. No additional adjustment on the part of the customer is necessary. The sensor provides a 4…20 mA output signal at 8 – 36 V voltage supply.

An integrated CMOS-DSP and EEPROM allow high accuracy in measurement capability. AMS 2712 comes as a pressure sensor module and is unilaterally mediaresistent due to underside pressurization*.

Pressure types and ranges for the AMS 2712

AMS 2712 (ultra low pressure) pressure ranges: differential or bidirectional differential: 0-5; 0-10 mbar or ±5 and ±10 mbar

AMS 2712 (low pressure) pressure ranges: differential or bidirectional differential: 0-20; 0-50; 0-100 mbar or ±20; ±50 and ±100 mbar

AMS 2712 pressure ranges: gage, differential or bidirectional differential: 0-200; 0-350; 0-1000 and 0-2000 mbar or ±200; ±350 and ±1000 mbar

AMS 2712 pressure ranges: absolute 1000 and 2000 mbar

AMS 2712 pressure range: barometric (absolute) 700-1200 mbar

Note: The AMS 2712 can also be calibrated to meet customer specifications. Further variants of the transmitter family are the AMS 2710 with a 10 V output, the AMS 2711 with a 5 V output, the AMS 4712 in a small plastic package and the AMS 3012 in a rugged metal housing for high system pressure*.
