Medium temperature and medium pressure type welding type thermocouple, thermal resistance of overall drilling protection tube using welding method to fixed seal with the main device
It can be used in measuring steam or water temperature in power factory’s pipes. According to the different pressures, temperatures and flowing speeds, there are two structures and installations for users to choose.
Socket Welding thermocouple And Resistor thermocouple with separate protective tube structure, elastic compression measurement components, with aluminum waterproof junction box, and other models of the junction box optional.
It has the following characteristics:
1) All use of armored components, pressure shock, stability, long life;
2) It’s elastic compacting structure between armored component and bottom of protecting tube,shorten the heat response time and enhance its anti-seismic capacity.
3) Large cavity junction box and novel wiring devices make wiring more reliable and easy.
4)The main body and protecting tube are detached structure. So that the user can change the temperature component when it’s working.
5). Deep blind hole processed overall protecting tube with uniform thickness in the bottom, without welding stress or intergranular corrosion hidden dangers. It’s pressure and shock proof, reliable and enduring. It can guarantee the safe work of machine set.
6. The overall drawing 650℃ high temperature armored Pt resistor component , Its vibration resistance and temperature limit can meet the large units of high precision and high reliability of the main steam temperature measurement.
