Problems solved by technology

Thermocouples have high temperature measurement accuracy and are basically reliable, but the temperature measurement area of ​​a single thermocouple is too small, so it must be arranged point by point when used in a large space, and still cannot meet the requirements of multi-point temperature measurement in a large space; single-point infrared measurement Temperature also has the problem of small temperature measurement area; optical fiber temperature measurement has problems such as large investment and insufficient position accuracy
