Principle and Application Range of Anti - corrosion Thermocouple
Anticorrosive thermocouple effect principle and scope of use analysis In the case of
Anticorrosive thermocouple principle and all the thermocouple, thermal resistance of the same, in addition to them than the general thermocouple protection tube more durable features, the basic structure and the general thermocouple, thermal resistance is roughly the same. Anti-corrosion type thermal resistance, thermocouple is designed for a variety of corrosive media temperature measurement manufacturing. According to the corrosion characteristics of the medium can choose different anti-corrosion materials, some special media for a particular physical and chemical properties and specially developed special anti-corrosion products, and according to user needs can also be fixed installation and junction box also has anti-corrosion performance, thus To achieve full anti-corrosion performance requirements.
Wear-resistant coating of the current two, a material hardness HRC58-62, temperature range 0-600 ℃; corrosion-resistant coating has good corrosion resistance, in addition to molten metal lithium, potassium, sodium, hydrofluoric acid, high Flow of liquid nitrogen, it is almost resistant to all other chemical media, in the 0-250 ℃ range of long-term use. If the fixed thread to make anti-corrosion structure, the thread can not work in the pressure environment.
Anticorrosive thermocouple for general thermocouple protection tube material is not competent occasions, such as various concentrations and temperatures of nitric acid, sulfuric acid, hydrochloric acid, phosphoric acid, sodium hydroxide, so in the petrochemical, pharmaceutical and other industrial fields can be widely used. Anti-corrosion thermocouple is suitable for measuring the mill mill mill mill temperature, the construction industry in the tube wear more serious occasions. Their common feature is that they can extend the service life of thermocouples and thermal resistors. The use of new anti-corrosion materials, coated with Teflon F46, suitable for petrochemical various corrosive media temperature.
