Effect factors of Thermocouple stability and solutions
Dec 22,2022
There are 5 possibilities if the thermocouple doesn’t work stable: 1. Bad contact for terminal and thermal electrode: Solution: clean the terminal and thermal electrode retighten. 2. Insulation fails which may bring intermittent short circuit and ground connection. Solution: find the fault point, repair the insulation. 3. Intermittence of the thermode or measuring therminal. Solution: If the break...

Advantages of Mineral Insulated Cables
Dec 22,2022
Thermocouples have been used for temperature measurement since 180 years ago. The original thermocouple was insulated by air that positive and negative horns hinged to the measuring end, then was developed to the assembly with protection tube, welded measuring end and ceramic insulation, we usually call this kind as the first generation of thermocouples. Until 30 years ago, the first great breakth...

Factors that affect accuracy of thermocouple
Dec 22,2022
The error in measuring temperature with thermocouples with any instruments is related several factors that combine together to affect the overall accuracy of the measurement: 1.Thermocople wire error:this is the error resulting from the fact that a given sample of bare thermocouple wire will not exactly meet the temperature versus millivolt relationship given the standard tables. The most accurate...

Do you know How does a thermocouple work?
Dec 22,2022
The principle of thermocouple is base on the binding ability of metal atoms(ions) to free electrons in metals related to temperature, different kinds of metal atoms(ions) have different binding abilities to free electrons. The metal on both sides of the fusion interface after two kinds of metals are welded together has different binding ability to free electrons, the large one is positively charge...

The common problems of thermocouple wires and solutions
Dec 22,2022
1.Use other types of wires instead of compensation thermocouple wires According to the operation principle of thermocouple temperature measurement, the thermoelectric potential of the thermocouple circuit is related to the measured temperature and the temperature of the thermocouple reference end. In the industrial site, the temperature of the thermocouple reference end is unstable and will be inf...

What is silicone rubber wire and cable?
Jan 29,2023
Silicone rubber is a chain structure formed by Si-O bonds, forming a helical molecular structure with small intermolecular force, free rotation and good resilience. The silicone rubber cable made of silicone material has better elasticity. The process principle is similar to that of rubber, and it is processed by mixing, high pressure molding and other processes. Temperature range: -40℃~180℃. Sili...
