System zur Temperatursteuerung durch Druckmessung in einem Fluessigkeit-Dampf-Prozess

摘要

A system for dynamically controlling the temperature of the liquid mass in a liquid-vapor phase process at a predetermined value. Pressure and temperature sensors are used to generate signals proportionate to the pressure and temperature within the vessel containing the liquid mass. The pressure signal is combined with a conversion factor to generate a calculated temperature signal. The calculated temperature signal is compared to the temperature sensor signal and the conversion factor is automatically corrected. The calculated temperature signal and a set temperature signal are compared to produce an error signal adapted to feed a temperature controller which controls heat transfer equipment regulating temperature of the liquid mass.
