Величина, пропорциональна разностному напр жению между измерительными точками 2 и 3, умножаетс на посто нный коэффициент К, который зависит от конструкций зонда , способа его установки в стенке машины 5, а также свойств приготавливаемой массы. Полученный результат складываетс с напр жением, возникающим в точке 2. Дл этого используетс суммирующий элемент 6, св занный с усилителем 7. Константа К дл каждого конкретного вида приготавливаемой массы определ етс один раз и выставл етс в элементе 6.abusing. the temperature on the measuring device is used ter 1ostat 4. The value, proportional to the difference voltage between measuring points 2 and 3, is multiplied by a constant coefficient K, which depends on the design of the probe, how it is installed in the wall of the machine 5, and the properties of the prepared mass. The result is added to the voltage arising at point 2. This is done using summing element 6 associated with amplifier 7. The constant K for each specific type of mass being prepared is determined once and set in element 6.
Дл индикации истинного значени температуры массы, т.е. скорректированной величины напр жени Ц, используетс индикаторный или регистрирующий прибор 8. Скорректированное значение напр жени Ц определ етс из выражени 11 U..(To indicate the true value of the mass temperature, i.e. of the corrected value of voltage C, the indicator or recording device 8 is used. The corrected value of voltage C is determined from the expression 11 U .. (
Вместо одного зонда могут быть использованы два зонда, в одном из которых термодатчик укреплен на конце зонда, а в другом - на боковой поверхности .Instead of one probe, two probes can be used, in one of which the thermal sensor is mounted on the end of the probe, and in the other - on the side surface.
На фиг. 2 показана схема суммирующего элемента 6, выполненного в виде комбинации сопротивлени .FIG. 2 shows a diagram of a summing element 6, made in the form of a combination of resistance.

Сложение напр жений -У± + К (Ui-Up,)Voltages Uj and 112 are applied to the midpoints at the extreme points of the resistance chain. Partial stresses multiplied by the corresponding components of the constant C 1 + K) AND 3 are also removed from the resistance circuit. 11.2 / 2 are subtracted due to the counter-insertion of thermoelements. Addition of stresses - У ± + К (Ui-Up,)

Таким образом, устройство позвол ет получать суммы и разности напр жений с учетом установленного значени константы в соответствии с заданным уравнением путем экстрапол ции.is achieved by appropriate selection of the pickup points of the resistance chain of the summing element. A decrease in the voltage in the summing element by a value of 11/2 is compensated by the amplifier 7. Thus, the device allows to obtain the sum and difference of voltages taking into account the set value of the constant in accordance with a given equation by extrapolation.
