Liquid Level Sensor Type AKS 4100/4100U,084H4521 Danfoss Sensors product introduction

The AKS 4100/4100U liquid level sensor is designed specifically to measure liquid levels in a wide range of refrigeration applications. The AKS4100/4100U liquid level sensor is 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 foruse with R744 (CO 2 ), HCFC, Non flammable HFC and R717 (Ammonia).The AKS 4100/4100U coaxial version should always be used for marine applications for all refrigerant types.The AKS 4100/4100U cable version should NOT be used for CO 2 or marine applications.Dust, foam, vapour, agitated surfaces, boiling surfaces,changes in density or in the dielectric constant , εr, 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.

Liquid Level Sensor Type AKS 4100/4100U,084H4521 Danfoss Sensors Features

• Approved and qualified by Danfoss for refrigeration applications

• One product covering several probe lengths(cable version)

• A single product for all commonly used refrigerants (cable version)

• Cable version requires less top-end clearance for installation and service

• Proven operation with all refrigerants in combination with oil.

• No need to clean cable version when fully covered by oil.

• The cable version is very compact and easy to handle, ship, install and use with different lengths and refrigerants

• Changes of the liquid dielectric constant (εr) do

not affect operation.

• 5000 mm / 197 in. probe length with cable version

• 2-wire loop powered; no separate transformer needed.

Please Note:

AKS 4100/4100U can be connected directly to Danfoss EKE 347 liquid level controller and thus be powered from EKE 347.If used together with Danfoss EKC 347 liquid level controller, a 14 – 30 V DC supply is required.

• Multi language HMI. Level and setting readout in mm,cm,m (ft, in.)

Language HMI versions:

- English (default), German, French, Spanish

- English (default),Japanese, Chinese Russian
