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 elds:

• 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 CO

• Robust construction gives protection against
mechanical inuences 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
