Устройство относится к измерительной технике и может быть использовано для измерений постоянных и переменных давлений в широком диапазоне рабочих температур. Существо решения заключается в наличии в составе тензометрического измерителя специального функционального преобразователя, позволяющем полностью компенсировать температурную погрешность при измерении давления. Функциональный преобразователь, содержащий помимо термозависимого элемента, дифференциальные усилители, блок опорных напряжений и умножитель, вырабатывает два температурозависимых напряжений Ut1 и Ut2, которые суммируясь в сумматорах с двумя выходными напряжениями Up1, Up2 мостовой измерительной схемы, позволяют получить выходной сигнал, независимый от температуры, и зарегистрировать его с помощью выходного прибора.The device relates to a measuring technique and can be used to measure constant and variable pressures in a wide range of operating temperatures. The essence of the solution lies in the presence of a special functional transducer in the strain gauge, which makes it possible to fully compensate for the temperature error in measuring pressure. Function generator comprising in addition to temperature dependent element, differential amplifiers, power reference voltages and the multiplier, produces two temperature-dependent voltage U t 1 and U t 2, which are summed in the adders with two output voltages U p 1, U p 2 bridge measurement circuit, allow to obtain output signal independent of temperature, and register it with an output device.
