Thermocouple is normal when using the matters needing attention

We are in daily use thermocouple places which need special attention? one We use the index number of thermocouples must be above and temperature measuring instrument required thermocouple is the same. At the time of installation of thermocouple, is to be able to stay away from relatively strong electromagnetic field, must try to avoid the power the power cord, is mainly to prevent temperature measuring instrument by outside interference. two Can't let the thermocouple work long time under the temperature of the load, or it will cause the thermocouple material changes, this will cause the thermocouple at the time of measurement error. If the measurement of low temperature, we can use outcrop type thermocouple to measure. A regular inspection for the casing of thermocouple and electrodes have damaged, if appear serious damage phenomenon, must immediately stop using, timely replace damaged thermocouples. In fact when the thermocouple is corrupted, we can take out, will damage all at the end of the reference end and measure the end actually can also be directly change over, welding up again, then check the gold can be used again. 3. Because the furnace body is a certain power, so the thermocouple is don't make any contact, and the furnace or losses caused by the voltage signal interference, this will cause the measurement error. When we insert the thermocouple or take out, be sure to try to avoid not too hot or too cold, main is to prevent the outside casing failure phenomenon. The installation of thermocouples must be level, mainly in order to prevent deformation and bending during downward installation and also check and rotational position on a regular basis. Four. In order to effectively guarantee the precision of measurement, so be sure to regularly check thermocouple. And regularly check between the thermocouple protection tube and sealing effect, main is afraid of the cold air into the protection tube, this will seriously affect the accuracy of measurement.
