| Abstract: | The design and realization of a low temperature measuring system are discussed. The feasibility of the design scheme has been sufficiently proved with a large amount of experimental studies. Based on basic principles of the sensor and its related circuits, using computer aided method, a scheme to realize the resistance temperature conversion is proposed with platinum resistance as sensor and bridge circuits as indicating instruments. The parameters and the structure of the low temperature measuring system are determined. |
