Conductivity Controllers Products

Hawker Electronics have continually improved upon the original conductivity level control principle to provide today the most comprehensive and reliable range of level controllers and associated hardware. Our controllers are unique in their design because of their close switching differential. This allows them to operate in contaminated liquids such as those with the presence of foam, wet rags and sewage.All our controllers employ low voltage AC in the electrode circuit and are available in AC or DC supply voltage supplies. ATEX and IECEx approved equipment is also available.
If you would like to see a video clip about the controller's ability to ignore ragging then follow this link and if you would like to see a video clip about the controller's ability to ignore foam then follow this link
This ability to ignore electrode contamination makes the Hawker controllers operate successfully in heavily contaminated liquids such as Combined Sewer Overflows ( CSOs) sewage and chemical applications


AC1 & AC1/P Controller for wall & panel mounting
