Product description:

Professional design for petrochemical industry department, can be directly measured - 200 ℃ to 1600 ℃ within the scope of liquid, steam and gas medium, as well as solid surface temperature measurement.

2, work principle,

The thermocouple electrode is composed of two different conductor material.When measuring the temperature difference is with the reference, the can produce thermoelectric power, the instrument will show thermoelectric potential corresponding temperature value.
Thermal resistance is to use the resistance and temperature had a certain function of relationship theory.When the measured medium temperature change, its resistance value also along with the change, the instrument will show resistance corresponding temperature value.

3, the main technical parameters

Product standards:

4, nominal pressure

Generally refers to the normal temperature, protecting tube can withstａnd static external pressure and not burst.Allows the working pressure is not only related to protecting tube material, diameter, wall thickness, and its structural forms, installation method and the measured medium velocity, species.

5, temperature range and tolerance
