摘要

The present invention relates to a reaction product viscosity detection method having a viscosity detection process including a rotation speed detection process and other processes. The rotation speed detection process is a process for detecting the rotation speed of an induction motor in which the power loss (PL) occurring when power (P) is supplied consists of a power loss (A) and a power loss (B) and includes: a step (?) in which the difference between the power (P) and the power loss (A) is assumed to be a first-order approximation value (PM1) of the mechanical output of the induction motor and a first-order approximation value of the rotation speed given by the equation N1 = NS(1 - S1) is obtained from the relationship between the output (PM1) of the induction motor and slip (S1) given by the equation PM1 = ?S1; a step (??) in which the power loss (B1) is obtained based on the first-order approximation value (N1); and a step (???) in which a second-order approximation value (PM2) is assumed to be given by the equation P - (A + B1) and a second-order approximation value given by the equation N2 = NS(1 - S2) is obtained from the relationship between the output (PM2) and slip (S2) given by the equation PM2 = ?S2.
