FIELD: heating.
SUBSTANCE: transmitter (10) of process parameters for measurement of temperature of a production process includes the first electrical connector (1) configured so that it can be connected to the first wire of the thermocouple; with that, the first electrical connector (1) includes the first electrode (1A) and the second electrode (1B). The first and the second electrodes are configured so that they can be connected to the first wire (18B) of the thermocouple. The second electrical connector (2) is configured so that it can be connected to the second wire (18A) of the thermocouple; with that, the second electrical connector (2) includes the third electrode (2A) and the fourth electrode (2B). The third and the fourth electrodes are configured so that they can be electrically connected to the second wire (18A) of the thermocouple. The second wire is made from material different from that of the first wire. Measuring circuit (28) is connected to the first and the second electrical connectors and configured with possibility of generation of an output signal related to thermocouple temperature. In addition, the measuring circuit is configured with possibility of determining polarity of the thermocouple based at least on one measurement made at least between two electrodes of the first, the second, the third and the fourth electrodes.
EFFECT: possibility of determining polarity of a thermocouple.
