                                                      Application
                                                      It is specially designed for power station to measure temperature for 30KW, 60KW power-generating set and concerned equipments. It is used to directly measure the temperature  of liquid, vapor, gas, and solid surface ranging from-200℃ to 800℃ during production process.
                                                      Operation Theory
                                                      Thermocouple electrodes are made of two different materials. Temperature difference between measuring end and reference end results in pyroelectric potential, then display meter indicates the corresponding temperature to the pyroelectic potential.
                                                      It is based on that temperature change of material results in change of its resistance. When resistance value changes, the working instrument will display relevant temperature value.
