 WZP-01T Petrochemical Thermal resistance is composed of two metal materials with different conductors. When the temperature difference between the measuring end and the reference end occurs, the thermal potential will be generated, which is called the output millivolt signal (MV). The working instrument will use this principle to convert and process the thermal potential, so that it can disp...
