Danfoss electronic level probe AKS

The AKS 4100 / 4100U level probe was specially developed to measure the liquid level of a wide variety of refrigerants including ammonia, HFCs, HCFCs and CO2 in containers, collectors, standpipes, etc.

AKS 4100 / AKS 4100U, electronic level probe

AKS 4100 / 4100U with TDR technology (guided radar) are optimally tailored to refrigeration applications. The AKS 4100 / 4100U level probe was specially developed to measure the liquid level of a wide variety of refrigerants including ammonia, HFCs, HCFCs and CO2 in containers, collectors, standpipes, etc.

The signal converter of the AKS 4100 / 4100U sends out electromagnetic impulses with low intensity and high frequency as well as with a pulse width of approx. 1 nanosecond, which move at the speed of light down the probe to the surface of the liquid. The pulses are reflected from the surface of the liquid and fed back along the probe. The impulses are received by the signal converter of the AKS 4100 / 4100U, analyzed and then converted into a readable liquid level. This method is called guided radar or TDR method (time domain reflectometry).

The AKS 4100 / 4100U in cable design is suitable for the most common refrigerants including ammonia, HCFC, HFC and non-corrosive gases / liquids (except CO2) and is available in various lengths between 800 mm and a maximum of 5,000 mm.

The coaxial version of the AKS 4100 / 4100U level probe is suitable for all industrial refrigeration applications (including marine refrigeration applications).

The cable version of the AKS 4100 / 4100U should not be used in CO2 or marine refrigeration applications.
