AMS 4712 analog pressure transmitter with 2-wire current output
Electrical connection AMS 4712
The AMS 4712 sensor is part of a series of miniaturized analog pressure transmitters* ready-to-use for air filter control, HVAC and medical applications. AMS 4712 is designed for fast screw assembly in a harsh industrial environment and fits for absolute, differential, gage and bidirectional differential pressure measurement.
One process of AMS 4712 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 4712 comes in a robust and compact plastic package (IP67) and is unilaterally mediaresistent due to underside pressurization*.
Pressure types and ranges for the AMS 4712
AMS 4712 (ultra low pressure) pressure ranges: differential or bidirectional differential: 0-5; 0-10 mbar or ±5 and ±10 mbar
AMS 4712 (low pressure) pressure ranges: differential or bidirectional differential: 0-20; 0-50; 0-100 mbar or ±20; ±50 and ±100 mbar
AMS 4712 pressure ranges: gage, differential or bidirectional differential: 0-200; 0-350; 0-500; 0-1000 and 0-2000 mbar or ±200; ±350 and ±1000 mbar
AMS 4712 pressure ranges: absolute 1000 and 2000 mbar
AMS 4712 pressure range: barometric (absolute) 700-1200 mbar
Note: The AMS 4712 can also be calibrated to meet customer specifications. Further variants of the transmitter family are the AMS 4710 with a 10 V output, the AMS 4711 with a 5 V output and the AMS 3012 in a rugged metal housing for high system pressure*.
