MODE AND AN ARRANGEMENT FOR MEASURING OF TEMPERATURE Russian patent published in 2007 - IPC G01K7/16 

FIELD: the invention refers to measuring technique and may be used for measuring of temperature of liquid and gaseous mediums.

SUBSTANCE: the invention is directed on expansion of functional possibilities due to introduction of additional functions of current diagnostics of the error at measuring temperature and simplification of the construction of the arrangement. The invention envisages usage of two thermal converters of resistance placed in one measuring sound and includes registration of output signals of the thermal converters of resistance, correction of one of the output signals with the aid of earlier captured output signals of the thermal converters of resistance received at their successive positioning in the medium with two different temperatures, definition on output signals of the thermal converters of resistance of the temperature of the medium and the error of its measuring. The arrangement has thermal converters of resistance located in one measuring sound, an exemplary resistor, a two-channel ADC, a microcontroller. At that the first outputs of the thermal converters of resistance are connected with the outputs of the ports of the microcontroller, with the first differential outputs of the two inputs of the ADC, the second outputs of the thermal converters of resistance are connected between themselves, with one output of the two exemplary resistor, with the second differential outputs of the two inputs of the ADC and with the first differential output of the input of voltage reference of the ADC, the other output of the exemplary resistor is connected with the second differential output of the input of with the first differential output of the input of voltage reference of the ADC, the other output of the exemplary resistor is connected with the second differential outputs of the input of voltage reference of the ADC and with the common wire of feeding.

EFFECT: expands functional possibilities.
