Pressure transmitter Type AKS 32R and AKS 2050 - 1

Data Sheet Pressure transmitter Type AKS 32R and AKS 2050 AKS 32R is a ratiometric pressure transmitter that converts the measured pressure to a linear output signal. The output signal is relative to the supply voltage meaning that the min. pressure output will be 10% of the actual supply voltage and the max. pressure output will be 90% of the actual supply voltage. At a supply voltage of 5 V, the output signal is: • 0.5 V at min pressure range • 4.5 V at max. pressure range The robust design and the ratiometric output signal makes the transmitter suitable for systems together with ratiometric A/D converters within a number of fields: • A/C systems • Refrigeration plant • CO2 plant • Process control • Laboratories Features • Highly developed sensor technology means great regulation accuracy • Selective temperature compensation • Compatible with all refrigerants incl. ammonia and CO2 • Robust construction gives protection against mechanical influences such as shock, vibration, and pressure surge • Polarity protected inlets • Sealed gauge measuring principle (pressure reference = 1013 mbar) • For use in zone 2 explosive atmospheres
