- Двухпроводный преобразователь 12, чувствительный к сигналам датчика перепада давления 30, включает постоянный модуль 28 и съемный модуль 26. Постоянный модуль 28 приспособлен для подсоединения к аналоговому съемному модулю 26, имеющему компенсационную емкость МАСД А, или к цифровому съемному модулю, имеющему компенсационную емкость СД Д. Схема компенсации емкости включена в постоянный модуль 28, который включает компенсационную емкость СД М 124, выбираемую посредством обеспечения равенства МАСД А и СД Д при калибровке аналогового съемного модуля 26 и цифрового съемного модуля. Это обеспечивает передаточную функцию давления, более линеаризированную и менее восприимчивую к изменениям температуры.
