Beschreibung
Zusammenfassung:	Thermal stress of a metal portion of a pressure-tight tube is calculated on the basis of calculated values of a temperature distribution calculator for calculating the distribution of temperature at positions equidistantly arranged in a direction of the thickness of the aforesaid tube on the basis of measured values of metal portion of the aforesaid tube, whereby the thermal stress being changed momently is accurately measured and monitored. Further, there is provided a calculation cycle for presetting calculation cycles on the basis of measured values of the fluid temperature in the aforesaid tube. The calculation cycles are made short when fluctuations in the measured values of the fluid temperature are large, while, the calculation cycles are made long when fluctuations in the measured values of the fluid temperature are small.
