<p>Device for temperature measurements, comprising a temperature-sensitive sensor (1) whose electrical properties, e.g. resistance, vary with the temperature, e.g. a thermistor (1), and which via two contacts (3, 4) is connected to two electric conductors (9, 10) arranged on a support (7), 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 (9, 10) on both sides of a support (8) made of plastics. The one metal layer (10) is interrupted by a gap (12) which is arranged to be bridged by the sensor (1), one contact (3 and 4, respectively) of which is connected to each conductor (10 and 9, 10", 11, respectively). Also a method for the manufacture of a device of the above-mentioned kind. A sheet (7a) of an electrically insulating material, e.g. plastics, coated with metal on both sides, is by said method electrically short-circuited along one edge; a gap, slit or the like (12a) being provided parallel with this edge, and the sheet being cut into strips (7) transversely to the short-circuiting (11, 11a) and to the said gap, slit or the like (12, 12a) with one contact (3, 4) connected to each metal coating (9, 10; 9a, 10a). </p> |
