FIELD: measuring technique. SUBSTANCE: device of well known structure for determining temperature of dew point, having a condensation surface, provided by cooler-heater, condensation surface temperature pickup, a unit for testing a state of the condensation surface, a recording unit, first and second analog-to-digital converters, a level detector, includes in addition a subtraction unit, two registers and a quantizing pulse generator, whose input is connected with an output of the first analog-to-digital converter and whose two outputs are connected with control inputs of the first and the second registers respectively. A data input of the first register is connected with an output of the second analog-to-digital converter, a data input of the second register is connected with an output of the first register; outputs of each registers are connected with respective input of the subtraction unit, whose output is joined with the level detector. EFFECT: enhanced accuracy of determination of dew point temperature in natural gases. |
