Shpatar P. Designing of electronic schemes of thermal values sensors

The dissertation is devoted to development of electronic schemes of thermal sizes sensors. Copper precision resistance thermal transducer is developed with the using of thin-tape technologies. Reduction of resistance throwing of R0 thermosensors is achieved on the stage of forming the thermoensitive element. Correction of resistance R0 is carried out with the help of laser. The discrete of correcting links - 0,5 Ohm, that is the size of throwing R0 of thermosensor resistance. The special attention is given a studying of sentinel stability of parameters at developed to resistance thermal transducer. The developed electronic schemes of capacity sensors for research of the thermal linear expansion coefficient with helping capacitance dilatometer. Analytical dependences of the capacity of the capacity transducer from the distance between unparallel rectangular and round plates were received. For the linear and protracting temperature into time at dilatometric and calorimetric investigations was linearly -variable voltage generator on a basis of copper precision thermal transducer of resistance is developed. On the basis of developed thermal sensors the row of devices is created: device for without contact temperature measuring, thermoanemometer, device for measuring of humidity of atmosphere into the corps of wares of electronic technique.
