ALSCHU 300 SP, Electrode Controller with Snap-On Housing for DIN Rail Mounting with 2 Signal Inputs

Applications:
Automatic control of drainage pumps and wastewater lifting plants, overflow and low liquid level control, automatic filling and draining of tanks, level control of liquid reservoirs, aquariums, storage tanks, etc.
The ALSCHU 300 ... is especially suitable for detection of conducting media (water, etc.). It is less applicable for badly or non conducting media (oils or fatty liquids), conducting foaming liquids or media causing electrically isolating deposits
on the electrodes.

 

Description:
The measuring method for level detection is based on the conductive principle, i.e. the electrical conductivity of the media is monitored. If the switching amplifier detects a value below the set conductivity the state ?media detected? is output, otherwise ?no media?. Depending on number and design of the connected level sensors the device can be used for level detection (min-/max- detection) or as 2-point controller.
