Disposable thermocouple is mainly composed of temperature measuring
probe and a big paper tube. Positive wire and negative wire of the
temperature measuring probe are welded to a compensating lead wire
embedded in a support bracket covered by a small paper tube. The
thermo wires are supported and protected by quartz. The temperature
measuring probe is covered by a cap to protect from dregs. All the
components are put into a thermocouple tip and are bonded by
fire-resistant filler into a whole. Therefore, the fast
thermocouple is for one-time use.
1, To select the appropriate length of protective paper tube and
temperature measuring gun according to the object and scope of the
2, Attach the disposable thermocouple to the temperature measuring
gun, make the pointer of the secondary instrument (or digital
display) back to zero. Begin to measure.
3, It is recommended to insert the disposable thermocouple in to
the molten steel at the depth of 300-400mm. Do not touch the
furnace wall or scum. Bring up the temperature measuring gun
immediately after the secondary instrument get results. The soak
time of disposable thermocouple in molten steel should less than 5
seconds, otherwise the gun may be burned out.
4, Change the used thermocouple into a new one, and pause for a few
minutes to get ready for the next measurement.
Ⅴ Transport and Storage
Be careful when assembling and removing the parts. Keep dry in the
transportational process. The products should be put into cases and
stored at warehouses where the relative humidity is less than 80%.
Keep the air flowing. The air should not contain harmful gases
which may corrode the products.
