Characteristics of modules of thermoelectric converters of pressure are resulted. United in complete set ПНТЭ-35 which are developed instead of out-of-date types and are intended. For especially exact measurement of levels of signals of variable pressure and currents. Measurement is carried out by comparison of thermal action of a signal and highly stable auxiliary constant pressure of the calibrated level. A range of frequencies and levels of measured signals of an alternating voltage: from 10 Hz to 200 MHz and from 3 мВ to 1100 In accordingly. A range of frequencies and levels of measured signals of an alternating current: from 10 Hz to 10 MHz and from 0,3 мА to 1, 5 мА.
