INSTALLATION AND USE
FIELD INSTALLATION
Industrial thermal resistance is used as a sensor to measure temperature. It is usually used together with display instruments, recording instruments and electronic regulators. It can directly measure the temperature of liquid, vapor and gaseous medium and solid surface in the range of -200 ℃ to 800 ℃ in various production processes.
According to national regulations, our company produces Pt100 platinum thermal resistors that comply with EC international standard graduation numbers and Cu50 copper thermal resistors that meet professional standard graduation numbers.
