Pressure Transmitter for A/C and Refrigeration, Type AKS 3000

  • AKS 3000 is a series of absolute transmitters with high-level signal conditioned current output, developed to meet demands in A/C and refrigeration. AKS 3000 utilizes the proved piezoresistive measuring principle, which has been used for decades in Danfoss pressure transmitters. The pressure reference is a sealed gauge. This means that atmospheric pressure variations have no influence on regulating accuracy. A must in accurate low pressure regulation. All materials in contact with the refrigerant and materials for the housing are AISI 316L stainless steel. No soft gaskets, all environmental sealings are made through laser weldings only. AKS 3000 has a 4 to 20 mA output, and is available with spade terminals for EN 175301-803 plug.

    Designed to meet A/C and refrigeration demands without compromising control accuracy concerning:

    Tough environment:

    • Vibration 
    • Shock during operation and transport 
    • Humidity and ice formation 
    • Temperature variations 
    • Corrosive media like ammonia gases and salt mist 


    Convenient performance: 

    • 4 – 20 mA signal 
    • 1% typical accuracy 
    • 0.5% typical linearity
