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

Cavitation, liquid hammer and pressure peaks may occur in liquid lled systems with changes in ow velocity, e.g. fast closing of a valve or pump starts and stops.

The problem may occur on the inlet and outlet side, even at rather low operating pressures.

Explosive atmosphere

Table 7: Explosive atmospheres

The products for ATEX Zone 2 are applicable in refrigeration applications employing any ammable refrigerants classied as IIA – please, refer to AKS installation guide. In ATEX Zone 2 applications at low temperatures cable and

plug must be protected against impact.

Table 8: Flammable refrigerants

For other products not ATEX Zone 2 assessed, an ignition risk assessment has been conducted with reference to IEC/EN 60335-2-89 (commercial refrigerating appliances) and IEC/EN 60335-2-40 (electrical heat pumps, airconditioners).

For countries where safety standards are not an indispensable part of the safety system, Danfoss recommends the installer to seek a third-party approval of the system containing ammable refrigerant. Note: Please, follow specic selection criteria stated in the data sheet for these particular refrigerants.
