Immersion thermocouples are used to monitor and control the temperature of liquid metal during melt preparation, holding, degassing and casting operations. Rapid response type expendable thermocouple is mainly composed of temperature probe and large paper tube. The positive and negative wires of the temperature probe are welded to the compensation wires embedded in the bracket covered by the small paper tube. The hot wire is supported and protected by quartz. The temperature probe is covered with a lid to prevent scum. All components are placed at the end of the thermocouple and bonded together with refractory filler.
- The world standard thread is the "heart" of the thermocouple tip and even the entire thermometer.
2. Excellent accuracy. Tolerance within 3 degrees Celsius.
3. It can be handled safely.
4. Range: 0 --- 1750 degrees Celsius.
5. Rapid response, measuring time no more than 6 seconds,
6. low thermal inertia, easy operation and maintenance.
Product Name | Graduation | Allowanble Tolerance | Max. Temperature | Response Time | Measured Rate | Remarks |
Expendable thermocouple | S | ±3 | 1650ºC | 4-6S | ≥98% | The length of thermocouples can be customized according to customers' requirement |
R | ±3 | 1650ºC | ||||
B | ±3 | 1750ºC | ||||
W | ±5 | 1750ºC |
- According to the object and scope of measurement, select an appropriate protective paper tube length
it means that the contact is good and the measurement can be carried out.
Even the immersion time in molten steel shall not exceed 5 seconds, otherwise it is easy to burn the temperature measuring gun.
stop for a few minutes, and prepare for the next measurement. Continuous measurement and dismantling are not allowed,
otherwise the temperature difference will fluctuate.
