The intelligent measuring converters are used for the information input into the technological process control systems. The wide IMC usage in the shields and the desks of the technological process control requires their high time and temperature stability. It is especially important to increase the continuous work duration without any tuning conjugated with the substantial labour and material expenditures. In addition, on purpose to reduce the prime price it is necessary to aspire to the maximally possible scheme and constructural simplicity, the efficiency and the exploitation comfort rising. In the working exploitation conditions the measurement error caused by the peculiarities of the connection lines and their contact e.m.f. can considerably influence. For example, using the thermo-electric sensors (TES) the connection lines are manufactured from the special thermoelectrode wires which in practice cause the errors adequate to the TES errors. The modern IMC usage is the considerable reserve of the thermo-electric thermometer exactness rising.
