Abstract

The invention relates to a device for temperature measurements, comprising a temperature-sensitive sensor whose electrical properties, e.g. resistance, vary with the temperature, e.g. a thermistor, and which via two contacts is connected to two electric conductors arranged on a support, which electric conductors in turn can be connected to a reading unit for the reading of the actual values of current, voltage or the like corresponding to the temperature. In a preferred embodiment the said electric conductors are in the form of two metal layers on both sides of a support made of plastics. The one metal layer is interrupted by a gap which is arranged to be bridged by the sensor, one contact of which is connected to each conductor.
