Thermal elongation determination arrangement for machine parts has trimming lines, which can be connected to first metal conductor whose electric resistance is proportional to average temperature of monitored area

摘要

The arrangement has a temperature sensor (1) from a first metal conductor (3) whose electric resistance is proportional to the average temperature of a monitored area. Trimming lines (T1-TN) in form of metal conductors are provided next to the first metal conductor and can be connected with the first conductor using electric connections (S1-SN). The electric resistance of the trimming lines is proportional to the average temperature of the area to be monitored.
