Iron and aluminum ceramic protection tube: aluminum-containing iron-based powder and subtly added A12O3 that prepared porcelain iron and aluminum (TLC) especially gold, the Fe-Al alloy porcelain thermocouple (resistance) protection tube, that is a ceramic iron and aluminum TC (resistance) of the most critical parts - iron and aluminum ceramic protective tube. According to operating temperature, wear, media type, pressure equation condition thermocouple sales, made of different series of iron and aluminum ceramic protection tube, the existing series: TLC, TLC1, TLC2, TLC3, TLC4 and TLC5 six series. TLC type: resistance to hydrochloric acid, nitric acid, sulfuric acid, resistance to sodium hydroxide, potassium hydroxide solution. Operating temperature is divided into 350 ° C, 750 ° C two kinds. Wear-resistance drain sleeve type thermocouple in some special occasions, such as chemical plants, refineries, power plants, cement plants, with ordinary thermocouple, RTD is easily damaged. Therefore, in these cases it is necessary to adopt wearable thermocouple (resistance). The thermocouple (resistance) especially for fluidized bed, the mill outlet thermocouple, primary and secondary air temperature coal and cement industries. In WR, WZ series, based on its protective sleeve insert portion thermocouple how to sell, may be made in whole or in part. Wearable thermocouple types, while resistant to erosion and corrosion resistance. Long life. At high temperatures can be used more than six months, at low temperatures can be used more than 8 months. Thermocouple, RTD for armor structure. Thermocouple type, Tianchang instrument linked instruments (certified), fast thermocouple instrument linked by Tianchang Instrument Sales Limited. Tianchang instrument Alliance Instrument Sales Co. (www.ylybxs.com) (www.ylybxs.com) is Chuzhou, temperature instrumentation leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
