Abstract
The disclosure relates to an apparatus for measuring temperature, comprising a temperature-sensitive sensor (1, 1'), whose electric properties, for example, resistance, vary with the temperature, for example, one thermistor (2, 2', 3 or 3') which is connected to electric lines (5, 6) which, in turn, may be connected to a read-off unit for reading off the values of current, voltage or the like corresponding to the temperature. In the apparatus according to the invention, the electric lines are disposed between two insulating layers (7, 8) which present mutually offset holes (9, 10) each in register with their respective line (5, 6), whereby these may easily be connected to different sensing terminals in the above-mentioned read-off units. The apparatus according to the invention is primarily intended to be used for medicinal temperature measurement, but may, naturally, also be used in other contexts, for example, in pure industrial application where a simple and economical but nevertheless reliable reading-off of temperature is desired.
