ABSTRACT:
A temperature measuring arrangement employs a semiconductor element whose internal resistance depends on the temperature and the current direction and which is driven by an a.c. signal from an a.c. signal source. A measuring device determines the difference in semiconductor element conductivity depending on the polarity of the applied a.c. signal to provide an indication of the temperature being measured.
