AKS4100U-084H4521 Danfoss Liquid Level Sensor

AKS4100U-084H4521 Danfoss Liquid Level Sensor product description

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 (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.

AKS4100U-084H4521 Danfoss Liquid Level Sensor 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.

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
