摘要:
A method of manufacturing temperature-sensitive instruments includes supplying first and second webs of insulating material in synchronism with each other to a work station, the first web having a series of first holes formed therein offset from a series of second holes formed in the second web. An electrical conductor is disposed transversely between the first and second webs such that the conductor forms pairs of conducting lines, one line of each pair being in register with a corresponding one of the first holes and the other line of each pair being in register with a corresponding one of the second holes. After connecting each pair of connecting lines to a temperature-sensitive sensor, the first and second webs are cut at spaced intervals between adjacent pairs of conducting lines to form a plurality of temperature-sensitive instruments.
摘要:
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.

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.
