Useful thermocouple temperature sensor life is a difficult prediction, even if most details of the application environment are known. Unfortunately, such information is often difficult to determine. Below, Velian solves some conditions that need attention when trying to determine the replacement timetable. For any temperature sensor, the best test is the actual installation, use, and evaluation that is considered to be designed to be designed. The suggestions and non -suggestions listed in the description of the thermocouple temperature sensor type are where the first time when the assembly style is selected in the process is selected.

 

 

All thermocouple temperature sensors must be calibrated when used. The problem is how fast this situation occurs. The performance of the thermocouple is seriously dependent on the absolute uniformity of physical and chemical properties in the length of the entire circuit. When producing thermoelectric component materials, take careful steps to ensure that this uniformity (or uniformity) should be achieved. During the use process, different parts of the circuit will go through different thermal and chemical exposure conditions. Therefore, the physical structures and compositions of these parts will indeed change from the original thermoelectric component wire.

 

 

Mechanical damage-protective tube, sheet, and even thermometer sleeve can fail, heat shock and mechanical wear.

 

Temperature super adjustment-processes can exceed the temperature and exposure elements to the temperature that is higher than expected, destroying the elements.

 

Human errors -control may be improper, the connection may be incorrect, and the inappropriate action of response operation conditions may be wrong.

 

 

The best way to solve the problem is to question the performance of the system: whether the performance meets the conditions? Will the changes in the control have a logical result? How about the product? Does its condition conform to the instrument explanation?
 
How to test the thermal power puppet used
 
The position of redundant-'detection "is placed in a new thermocouple. There is a known output and suspicious one in the operation process, and compares the reading.
 
Disassembling and replacement -if two sensors are installed at the same time, the suspicious probe is disassembled and replaced with another probe that is known to work normally, and the readings are compared.
 
In order to achieve long -term reliable thermocouple life, the usual strategy is to comfortably operate the equipment at its highest temperature and provide the cleanest environment. Shells, such as sheets, protective tubes, and thermometer sleeves, are common means of controlling the actual environment of the thermal components themselves. The temperature instrument redundant school is a good process.
