Resistance Thermometers Standard Grade 3 TSP 0307-02 for Accurate Temperature Measurement

Designed for verification of working measuring instruments, as well as for accurate temperature measurements in the temperature ranges, °?: from minus 196 to 0; 0 to 419,527; 0 to 660,323. The principle of operation of thermometers is based on the dependence of electrical resistance of platinum on temperature. The main part of thermometers is a sensitive element consisting of a platinum wire spirally arranged in a four-channel ceramic tube. Thermometers have four outputs - two current and two potential, the resistance measurement of thermometers is carried out by a four-wire scheme.
