Device for on-line detecting water scale formation

The utility model relates to a water scaling on-line detecting device, which is characterized in that the structure consists of there parts: (1) a detecting body 13 being composed of a scaling detecting piece 1, a heat transfer body 2, a heating element 3 and a scaling temperature measurement element 11; (2) a support tube 5; and (3) an equipment jointing sleeve 6. The different feedback influences of the scaling difference in temperature caused by the increase of the scaling thickness in different conditions can be directly measured or characterized, therefore the dynamic and real-time objective evaluation of the scaling condition of the water system and the scale-preventative effect after the water handing can be realized.
