ST Series Sheathed Thermocouple

ST series sheathed thermocouple is especially suitable for installation in temperature measurement occasions where the pipeline is narrow, curved and requires rapid response and miniaturization.It has the advantages of slender body, fast thermal response, vibration resistance, long service life and easy bending. Sheathed thermocouple is usually used in conjunction with display instruments, recording instruments, electronic computers and etc. It can directly measure liquid, steam, gas medium and solid surface with temperature in the range of -200℃~1500℃ in various production processes.It is widely used in petrochemical, electric power, metallurgy and other industries.
