084H4521 Danfoss AKS 4100U Liquid Level Sensor - Cable Version

The Danfoss AKS 4100U liquid level sensor is designed specifically to measure liquid levels in a wide range of refrigeration applications.

Danfoss AKS 4100/4100U liquid level sensors are based on a proven techhology called Time Domain Reflectometry (TDR) or Guided Micro Wave. AKS 4100/4100U liquid level sensor can be used to measure the liquid level of many different refrigerants in vessels, accumulators, receivers, standpipes, etc.

The electrical output is a 2-wired, loop powered 4 - 20 mA output signal, which is proportional to the refrigerant liquid level. AKS 4100/4100U in a cable version is suitable for HCFC, non-flammable HFC and R717 (ammonia), and differing lengths from 800 mm / 31.5 in. and up to 5000 mm / 197 in.. The coaxial version of AKS 4100/4100U is designed for use with R744 (CO2), HCFC, non-flammable HFC and R717 (ammonia). The AKS 4100/4100U coaxial version should always be used for marine applications for all refrigerant types.

Danfoss AKS 4100/4100U cable versions should NOT be used for CO2 or marine applications. Dust, foam, vapor, agitated surfaces, boiling surfaces, changes in density or in the dielectric constant for the liquid have no influence on the AKS 4100/4100U performance. Oil accumulated in the bottom of a standpipe will not disturb the liquid level signal and it is not necessary to remove AKS 4100/4100U for cleaning after oil has been drained out of the standpipe.
