Abstract:
1. A device for controlling deposits on surfaces, comprising: at least one body having two opposite longitudinal end surfaces and a surface on an outside of said body on which deposits occur and influence reflection properties of said surface to electromagnetic radiation inside said body; at least one transmitter for transmitting electromagnetic radiation to said at least one body and reflecting the electromagnetic radiation off said surface inside said body, said at least one, transmitter disposed at one of said opposite longitudinal end surfaces and being connected to said at least one body; at least one detector for detecting a presence of the deposits at said surface, said at least one detector disposed at one of said opposite longitudinal end surfaces and being connected to said at least one body and measuring electromagnetic radiation received from said at least one transmitter after reflection at said surface, said at least one detector generating signals based upon the presence of deposits detected at said surface; and at least one ion exchanger connected to said detector for controlling the deposits at said surface, said at least one ion exchanger controlling the deposits in dependence on the signals generated by said at least one detector.
