摘要： A device for detecting a coagulation in a mixed phase container, such as a fluidized bed type olefin polymerization reactor, includes at least one coagulation detecting part mounted on an inner surface of the reactor, and a coagulation detecting circuit for outputting an electrical signal in response to a change in capacitance between a main electrode of the coagulation detecting part and the surrounding inner surface of the reactor. When any coagulation is attached on the inner surface of the mixed phase container, the state of production of the coagulation can be obtained from a change in output signal from the coagulation detecting circuit connected to the coagulation detecting part.
