Detailed Product Description

The Working Principle of Thermocouple(Thermal Resistance)

1.The Electrode of Thermocouple is made up of two different conductor materials, when temperature difference between measure terminal and standard terminal exists, therminal electromotive force appears. Working meter shows temperature that corresponding to thermal electromotive force

2.Thermal resistance is made use of the principle that there is reference relationship between the resistance and temperature. When there is temperature difference in measured mediums, there will be thermal resistance, working meter will be thermal resistance, working meter will show the tempereture corresponding to the resistance

The Applicaiton

Special design for petroleum chemical industry, can measure the surface temperature of liquid, steam, and gas medium from 200^oC to 1600^oC

The Main Technical Parameter

i.Standard: IEC 1515, IEC 584, IEC 751, JB/T 5518-91, JB/T 5582-91

ii.Nominal Pressure: It is usually means the static outer preesure which the protection tube can offer and will not be broken under the working temperature, In fact, working pressure not only has relationship with protection tube material, diameter and thickness of wall, but also the structure form, installation form, installation method, inserting depth and the flow speed and type of the medium ect
