Special Thermocouple(Thermal Resistance)

Detailed Product Description

The Main Technical Parameters of Thermocouple:

1.Standard:

       IEC 1515

        EC 584

       IEC 751

       JB/T 5582-91

       JB/T 8622-1997

       JB/T 8623-1997

2.Nominal Pressure

It is usually means the static outer pressure 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 method, inserting depth and the flow speed and type of the medium etc.

Insulation Resistance at Normal Temperature: The insulation resistance is no less than 1000MΩ, munder condition that environment temperature is 20±15^oC, relative humidity is no more than 80% and testing voltage is 500±50V(D.C);

The insulation resistance of Pt thermal resistance is less than 100MΩ and the Cu thermal resistance is no less than 50MΩ under condition that environment temperature is 15~35^oC, relative humidity is no more than 80% and testing voltage is 10~100v(D.C).

The Application:

Special structure design for different occasions, can measure the surface tmperature of liquid, steam and gas mediums ranging from 200^oC~1600^oC directly

The Working Principle:

The two electrodes of sheathed thermocouple are made of different conductor materials.W here there is temperature difference between measuring end and reference end, there will be hydroelectric potential, then the meter shows the corresponding temperature of the hydroelectric potential
