The Danish pioneer for natural refrigerant technology is updating its product portfolio on ammonia21.com to add a new range of guided radar liquid level sensors. Targeted to the industrial refrigeration segment, the sensors are suitable for different refrigerants including ammonia.
The new AKS 4100/4100U liquid level sensor from Danfoss introduces the proven guided radar technology fully adapted for industrial refrigeration. Featuring high flexibility and reliability, the liquid level sensor is designed specifically to measure liquid levels of many different refrigerants, including ammonia, in vessels, accumulators, receivers, standpipes, etc.
Due to the very easy on-site adjustment procedure with AKS 4100/4100U, significant time-savings during installation can be ensured.
Basic specifications of AKS 4100 and AKS 4100U
The difference between the two products AKS 4100 and AKS 4100U are the connections. The AKS 4100 has a G1 in. pipe thread connection whereas the AKS 4100U has a ¾ in. NPT
connection.
AKS 4100/4100U liquid level sensors are available in two different versions:
Cable version
The Guided Radar (TDR technology - Time Domain Reflectometry) measuring principle
The AKS 4100/4100U signal converter emits low-intensity, high frequency electromagnetic pulses with a width of approximately 1 nanosecond, which travel at the speed of light along the probe down to the liquid surface.
The pulses are reflected by the liquid surface, guided back along the probe, and received and analysed by the AKS 4100/4100U signal converter and then converted into a liquid level reading. This method is called Guided Radar (Time Domain Reflectometry (TDR)).
