Method for making thermistors, preferably with the aid of thick film technique whereby a pattern (2, 3, 4) of an electrically conducting material is printed onto a base plate (1) of electrically non-conducting material, a second pattern (5, 6, 7) is printed with a thermistor material in such a way that parts of the base plate not covered by the first pattern are bridged by the thermistor material. The ready-printed and hardened base plate (1) is divided into thermistors including at least two contacts (2a, 3a) from the first-mentioned pattern and a part (5a) from the other pattern bridging the surface between these contacts. Before the cutting takes place the resistance between the two contacts or with its attached or equal parts from the first pattern are first measured and the cutting afterwards is done in relation to this measurement. …<??>The invention also includes a thermistor or a double thermistor manufactured according to the method described above and a thermometer including such thermistor encased in an outer heat conducting but not electrically conducting wrap (19, 20, 21, 22) as well as through its contacts connected to two leads (17, 18) accessible from outside (through holes 24, 25). |
