Thermocouple good or bad judgment?

the main use in production and manufacturing is becoming more and more common. infrared thermometer has become one of the most common temperature measuring components in industrial production. it has high measurement accuracy, wide coverage of accurate measurement and simple structure, features such as ease of use. We in accordance with a variety of ways to master and analyze the goods, for many netizens to show all aspects of the manufacturing industry expertise.

then let's master the analysis of platinum resistance good ring?

high-precision inspection instrument the basic concept of temperature measurement is that copper foil made of materials in these two different situations forms a closed loop. when there are temperature fields on both sides, there will be current flow in the control loop, at this time, there is induced electromotive force in the middle of both sides-thermal induced electromotive force, which means the white Seebeck effect. The gas adsorption copper foil in these two different situations is a thermal reference electrode, the higher end of the room temperature can be the upper end of the work, the lower end of the room temperature can be the free end, the free end is usually at a stable room temperature.

platinum resistance is undoubtedly damaged or even destroyed after being used for a certain period of time. normally, the good ring of platinum resistance is related to the platinum resistance wire (wire) inside it. however, how to analyze the good ring of even wire is a simple discussion on this difficult problem.

at the beginning, it is judged that there is no problem with the surface of the platinum resistance wire. whether it is good or bad can only be judged according to the measurement.

put the measured high precision controller wire into the column tube heating furnace together with the platinum resistance special type porcelain waterproof sleeve and the standard wear-resistant thermocouple, the hot end was inserted into a column made of metallic nickel for heat soaking having a porous structure in a tubular furnace. Place the separate platinum resistance thermometers in a vessel maintained at twenty degrees Celsius using ice.

Maintain the tube heating furnace at the allowable temperature of the platinum resistance, and maintain this range smoothly. At this moment, the thermoelectric potential energy caused by the standard thermocouple and the measured platinum resistance was measured and recorded with the Hui m1941 multi-purpose meter that has been measured and reached the standard. Based on the recorded thermoelectric potential, consult the measurement range table to determine the corresponding ambient temperature. If the measured platinum resistance deviates, it can be deemed non‑conforming.
