{_ComName}

The fast temperature measuring thermocouple is mainly composed of a temperature measuring head and a large paper tube. The even head mainly has positive and negative even wires welded to the compensation wire, and the compensation wire is embedded in the bracket. The bracket has a small paper tube, and the even wire is supported and protected by quartz. The outermost part is equipped with a slag-proof cap. All components are packed into the mud head and bonded into a whole with a refractory filler. They cannot be disassembled, so they are disposable.

Structure of fast temperature measuring thermocouple:

Thermocouple is mainly composed of a thermocouple and a large paper tube. The even head mainly has positive and negative even wires welded to the compensation wire, and the compensation wire is embedded in the bracket.

Working principle of fast temperature measuring thermocouple:

Fast temperature measuring thermocouple is used to measure the temperature of molten steel, molten iron and other high temperature molten metals. It is a consumable thermocouple. Its working principle is to measure the temperature of molten steel, molten iron and high-temperature molten metal by using the thermoelectric potential generated at both ends of the thermocouple according to the thermoelectric effect of the metal.

Features of fast temperature measuring thermocouple:

1. High accuracy and good stability. Microcomputer processing control automatically calibrates the circuit to zero, full scale and cold junction temperature. Adopts precision reference voltage regulator with long-term stability. Software technology ensures that the meter is accurate and reliable.

2, strong anti-interference ability

3. LED super high brightness digital tube display.

4. Complete functions and easy to expand, can be equipped with printing interface.

5. Equipped with isolated parallel BLD code output; or 4-20mA (1-5V) analog output port.

6. The internal main board is equipped with index number conversion short circuit. Each meter can be equipped with 2 different thermocouples with different index numbers.

7. It can be used for both rapid temperature measurement and continuous temperature measurement.

How to use the fast temperature measuring thermocouple:

1. According to the measurement object and range, select different types of thermocouples, protective paper tubes of appropriate length, and suitable temperature measurement guns.

2. Put the fast thermocouple on the temperature measuring rod and insert it tightly, so that the secondary instrument pointer (or digital display) returns to zero. At this time, it indicates that the contact is good and the measurement can be performed.

3. It is advisable to insert the fast thermocouple into the high-temperature molten metal at a depth of about 100mm. Do not measure the furnace wall or slag during the measurement, so that it is fast, stable, and accurate. When the secondary meter obtains the result, you should immediately raise the gun. The thermocouple must not be immersed in hot metal for more than 5 seconds, otherwise it will burn easily.

4. After the temperature measuring gun is lifted out of the high-temperature molten metal, remove the used thermocouple and install a new one, pause for a few minutes, and prepare for the next measurement. Do not connect and disconnect, otherwise it will cause inaccurate measurement and easily damage the temperature measuring gun.

Transport and storage of rapid temperature thermocouples:

The fast temperature measuring thermocouple should be handled carefully during loading and unloading. During transportation, it must not be wet. The product should be stored at a relative temperature of not more than 80%. In the warehouse.
