New AKS4100 sensors
Danfoss is going to replace AKS41 sensor series with a new AKS 4100 liquid level sensor series. Since 2012 AKS41 will not be manufactured.
The AKS 4100 liquid level sensor is based on a proven techhology called Time Domain Reflectometry (TDR) or Guided Micro Wave.
AKS 4100 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 in a cable version is suitable for most commonly used refrigerants, including R717(ammonia), HCFC, HFC and non corrosive gases/liquids except CO2, 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 CO2. It can also be used for all other appoved commonly used refrigerants.
The AKS 4100 coaxial version should always be used for marine applications for all refrigerant types.
The AKS 4100 cable version should NOT be used for CO2 or marine applications.
