The КФП-2 phase transition controller was designed and tested. Controller is the element of the System for continuous water mass fracture control in ammonium nitrate melt and carbamide. Controller complete with concentration sensors ДК-КС are intended for automatic continuous water mass fracture determination in the technological flow of ammonium nitrate solution and carbamide. Water mass fracture determination is performed by crystallization temperature. The controller has two independent channels for connection of two sensors. Obtained data in digital and analog forms can be transmitted to SCADA systems.
