we are the topmost exporter, manufacturer and supplier of silicon nitride ceramic thermocouple protection tube in Zibo, Shandong Sheng, China. With the progress of science and technology, the temperature measurement technology has developed rapidly. Thermocouple has become the most widely used components in the area of industrial production and scientific research due to its reliable and accurate performance, simple structure, convenient operation, wide temperature range and signal remote transmission.
Thermocouple protection tube plays an important role in the temperature measurement. The material of protection tube affects the long-term stability and service life of thermocouple. Especially for the thermocouple working under high temperature, the requirements on the materials of protection sheath is higher, like molten aluminium continuous temperature measurement, the thermocouple protection sheath not only suffer the high temperature, but also the corrosion and impact of molten aluminium.
Silicon nitride thermocouple protection tube is developed to well protect the thermocouple work under poor environment with high temperature and corrosion. Thermocouple protection sheath made from silicon nitride are widely used in foundry industries like aluminium, zinc and copper casting, it will not wetted with molten metal and will well resist the temperature difference. Silicon nitride ceramic is the best choice for thermocoulpe protection tube with high cost performance and long service life.
