Introduction of Temperature Meter Thermocouple Indexing Table and Usage

Thermocouple temperature meters have been widely used in industrial production measurement. If we want to use thermocouples correctly and effectively, companies must first understand thermocouple index tables. Let's analyze it.

Thermocouple thermoelectric potential and temperature of the corresponding relationship in a table called the thermocouple index table. Normally, when we test or measure a temperature instrument thermocouple, the power meter measures the thermoelectric value of the thermocouple (bucket V) instead of the temperature (°C). This requires converting the measured thermoelectric value into a temperature value, which is what the thermocouple index table does.

The thermocouple index table is mainly used to convert the measured electromotive force to the corresponding measured temperature, and can in turn convert the temperature to the thermoelectric potential of the corresponding thermocouple.

The national standard GB/T 16839.1 “Thermocouple Part 1: Index Table” provides eight kinds of standardized thermocouple indexing tables. They are:

1, platinum rhodium 13 Platinum (R type);

2. platinum rhodium 10 platinum (S type);

3, platinum crucible 30 a platinum crucible 6 (B type);.

4, iron-copper and nickel (J type);

5. Copper-nickel-copper (T-type);

6, nickel-chromium-copper-nickel (E type);

7, nickel-chromium-nickel-aluminum (K-type);

8, nickel chromium silicon nickel silicon (N type).

Here are 3 points we need to pay attention to:

1. In each table of the index table, the reference temperature is 0cC.

2. £ in the table. /°C refers to the 1990 international temperature scale, and the temperature unit is c.

3. In the table, E/bucket V means that the unit of thermoelectric power (E) is bucket V.

The correct and effective measurement of the temperature of the medium allows us to carry out the key to job production. Through the introduction of the function and use of the temperature meter thermocouple index table, it is hoped that it will help the staff in the measurement process.
