Eine Regelelektronik überwacht-über einen nach halber Länge des Rohres 1 angeordneten Halbleiter-IHihlei? die Temperatur des Öles, dies.ermöglicht einen Wechsel derÖleintrittsseite bei gleichbleibender Austrittstemperatur. Über Halbleiter, Dioden und. einen Thyristor erfolgt die Steuerung der Temperatur in der Weise, daß die an der Heizwicklung 2 anliegende Spannung durch Anschneiden der oberen. Halbwelle reduziert wird, sofern der vorgegebene Wert überschritten wird. Bei Überschreitung des Sollwertes ist eine Regelung bis lull Volt möglich. Die Regelelektronik ist so geeicht, daß bei Schwankungen, des. Öldurc:hsatzes zwischen 100$ und 3 Öfo konstante Austrittstemperatur en gemessen werden. Der .Sollwert kann über ein Potentiometer vorgegeben werden»Control electronics monitor - via a semiconductor device arranged halfway along the length of the tube 1? the temperature of the oil, this enables the oil inlet side to be changed while the outlet temperature remains the same. About semiconductors, diodes and. A thyristor is used to control the temperature in such a way that the voltage applied to the heating coil 2 by cutting the upper. Half-wave is reduced if the specified value is exceeded. If the setpoint is exceeded, regulation down to zero volts is possible. The control electronics are calibrated in such a way that constant outlet temperatures are measured in the event of fluctuations in the oil flow rate between 100 $ and 3 Öfo. The setpoint can be specified using a potentiometer »
