AKS4100U-084H4521 liquid level sensor produced by Danfoss details

The AKS 4100/4100U liquid level sensor is designed  specifically to measure liquid levels in a wide range of  refrigeration applications.  The AKS 4100/4100U 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 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. The AKS 4100/4100U cable version should NOT be used  for CO2 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.

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
