METHOD MEASURING MEAN VALUE OF PARAMETER, SPECIFICALLY TEMPERATURE, OF HETEROGENEOUS MEDIUM Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: method is intended for usage in systems controlling environment and technological processes. Method measuring mean value of parameter, specifically temperature, of heterogeneous medium includes conversion of current values of parameters to proportional voltage with the aid of temperature sensitive elements, formation of sweeping voltage, its comparison with current output voltage of each temperature sensitive element. At moment of equality of compared voltages current value of sweeping voltage is evaluated at some temperature sensitive element and it is added to collected sum of such voltages. After sweeping voltage reaches maximum value collected sum is divided by number of temperature sensitive elements in group. Obtained quotient is assumed to be measured mean value of parameter. EFFECT: decreased number of temperature sensitive elements and expedited tuning of devices realizing this method. 2 cl, 2 dwg
