Protection Tube For Thermocouple

Protection Tube for Thermocouple

Si3N4 material is applied to protection tube for thermocouple.long using life,maintenance free,widely used as amainmaterial of protection tubes for thermocouple.As thenecessary means of measuring temperature, thermocoupleprotection tube is used in Aluminum, Tin,Lead, Zinc etc. kindsof Metallurgical industry .The advantages are :

• Si3N4 material has the better thermal shock resistance andhigh-temp mechanical strength, light weight,high strength.
• easy to handle. Even exchange in the processing, there is noburst, easy to produce and maintain.
• Si3N4 material has the low conductive advantage, its lowspecific heat allows minimum heat loss. This aides in moreaccurate temperature measurements for our thermocoupleprotection tube application,thus facilitates molten metal heattransfer in our stalk tube applications. This advantage canreduce temperature of aluminum and overall energy costs.
• Molten aluminum low wettability, there is no elutedcontamination into molten aluminum, therefore, the purity ofthe metal ismaintained.
• Si3N4 has the excellent corrosion resistance,nearly inertagainst molten aluminum, so it ensures longer life.
