Anticorrosion working principle of thermocouple and all of the thermocouple, heat resistance is the same, they besides have the characteristics of the thermocouple protection tube is more durable than general, its basic structure and general thermocouple, heat resistance is roughly the same. Anti-corrosion type of thermal resistance, thermocouple is designed for all kinds of corrosive medium temperature measurement made in production. According to the properties of corrosion medium can choose different corrosion materials, have a plenty of concerning the special physical and chemical properties of a medium specially developed special anti-corrosion products, and according to user needs can also be used for fixed installation device and junction box also has antiseptic properties, so as to be completely anticorrosive performance requirements.
wear resistant coating is two kinds, one kind of material hardness HRC58 - 0-62, temperature measurement range 600℃; Corrosion type coating has good anti-corrosion performance, in addition to the molten metal lithium, potassium, sodium, hydrofluoric acid, high flow rate of liquid nitrogen, it can resist almost all other chemical medium, at 0 250 ℃ within the scope of use for a long time. If the fixed screw to make the corrosion structure, then the thread can't work under pressure.
the anti-corrosion thermocouple is applicable to general thermocouple protection tube material is not up to the occasion, such as a variety of concentration and temperature of nitric acid, sulfuric acid, hydrochloric acid, phosphoric acid, sodium hydroxide, etc. , so the oil can be widely used in chemical, pharmaceutical and other industries. Anticorrosion of thermocouple is suitable for measuring the power plant coal mill grinding temperature, tube wear serious situations in construction industry. Their common characteristic is can prolong the service life of the thermocouple, heat resistance. Adopt new anti-corrosion materials, outsourcing ptfe F46, applicable to petrochemical various kinds of corrosive medium temperature measurement.
