What are the advantages of armored thermocouples?

What are the advantages of armored thermocouples?There are also many types of thermocouples, including platinum-rhodium thermocouples, wear-resistant thermocouples, corrosion-resistant thermocouples, assembled thermocouples, and so on. Among them, the range of use of armored thermocouples is also very wide, and they are used in many industries. So what are the advantages of armored thermocouples? The following is introduced by Anhui Tiankang (Group) Co., Ltd .:
1. Small thermal inertia, fast response to measured temperature, and small time constant. For example,the minimum time constant of ordinary thermocouples is less than or equal to 20 seconds, and the larger is about 20 seconds to 4 minutes, while the time constant of outcropping armored thermocouples is 0.05 seconds, the shell type is 0,3 seconds, and the insulation type For 1.5 seconds.
2. Because the volume of the thermal contact is small, the thermal capacity is small, and the temperature of the measured object with a small thermal capacity can be measured more accurately.
3. Great flexibility. Because the protective tube material is annealed, it has good flexibility and can be bent into various shapes to meet the installation requirements of complex structures.
4. Due to the solid structure of the assembly, good mechanical properties, resistance to vibration and shock, it can adapt to the measurement of various special conditions.
Because of the above advantages, armored thermocouples are widely used in various industrial sectors. The shortcomings are due to the thin wall of the thin wire, the life at the highest temperature is lower than the corresponding ordinary thermocouple.
