Description

Фазочувствительна  электроизмерительна  схема 7, св занна  с генератором 6, выдел ет переменную составл юндую сигнала W и формирует выходной электрический сигнал е, пронорциональный перепаду и несущий информацию о его знаке, в форме, удобной дл  последующего использовани .The phase-sensitive electrical measuring circuit 7 connected to the generator 6 separates the variable component of the signal W and generates an electrical output signal e, a proportional difference and carrying information about its sign, in a form suitable for subsequent use.

Опорное давление может быть как больще (фиг. 2), так и меньще преобразуемых давлений и определ етс  конкретными услови ми работы преобразовател .The reference pressure can be both larger (Fig. 2) or less than the convertible pressures and is determined by the specific conditions of operation of the converter.
