How to calculate the quota of double thermocouple sets

1. Calculation method of double-branch thermocouple sleeve quota
Double-branch thermocouple sleeve quota is a common device for measuring temperature. A common calculation method is introduced below.

2. Calculation steps
? First, the two contacts of the thermocouple are in contact with the upper and lower surfaces of the measured object respectively.

? Determine the thickness of the measured object and record its value as h.

? Measure the resistance between the two contact points and record its value as R.

? Measure the ambient temperature and record its value as T0.

3. Calculation formula
According to the voltage-temperature relationship of the thermocouple, the temperature difference can be calculated using the following formula:

△T=[(R-R0)/α]*1000

Where R0 is the resistance of R at ambient temperature, and α is the temperature coefficient of the thermocouple.

After the temperature difference is calculated, the actual temperature can be calculated based on the ambient temperature and the temperature difference.

4. Precautions
? When calculating the double-branch thermocouple sleeve quota, ensure that the thermocouple is in good contact with the measured object to obtain accurate measurement results.

?When recording the temperature, be sure to record both the ambient temperature and the actual temperature.

?When using the calculation formula, use the correct parameter value to avoid calculation errors.

The above is an introduction to the calculation method of the double thermocouple set quota. Through correct calculation, we can accurately measure the temperature and provide effective monitoring and control for various industrial processes.
