Danfoss AKS 32, AKS 33 Data sheet

Data Sheet

Pressure transmitter Type AKS 32 and AKS 33

AKS 32 and AKS 33 are pressure transmitters that measure a pressure and convert the measured value to a standard signal:

• 1 – 5 V DC or 0 – 10 V DC for AKS 32

• 4 – 20 mA for AKS 33

A robust design makes the AKS very suitable for application within a number of elds e.g.

• Air conditioning systems

• Refrigeration plant

• Process control

• Laboratories

Pressure transmitter, Type AKS 32 and AKS 33

Features

Highly developed sensor technology means high pressure regulation accuracy, a very important factor in the precise and energy-economic capacity regulation of refrigeration plants.

• Fully digitally compensated, developed specially for refrigeration plants.

◦ LP: -30 – 40 °C (≤ 16 bar) ◦ HP: 0 – 80 °C (> 16 bar)

• Compatibility with all refrigerants incl. ammonia means less stock and greater application exibility

• Built-in voltage stabiliser, i.e. the AKS pressure transmitters can be powered from an unregulated voltage supply of any output within given limits

• Eective protection against moisture means that the sensor can be mounted in very harsh environments, e.g. in the suction line encapsulated in an ice block

• Robust construction gives protection against mechanical inuences such as shock, vibration and pressure surge. AKS sensors can be mounted direct on to the plant application

• No adjustment necessary. With the highly developed sensor technology and sealed gauge principle, the accuracy of the factory setting is maintained independent of variations in ambient temperature and atmospheric pressure. This is very important when ensuring evaporating pressure control in air conditioning and refrigeration applications

• EMC protection according to EU EMC-directive (CE-marked)

• UL approved

• Polarity protected inputs

• For use in zone ATEX 2 explosive atmospheres

Table 6: 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 7: Explosive atmospheres

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.
