Thermocouple is a common temperature measuring element in the temperature measurement instrument, which directly measures the temperature, and convert the temperature signal into a thermoelectric potential signal.
RTD Temperature sensors are commonly used for temperature measurement in high-temperature areas of industry because of their simple construction, wide temperature range, ease of use, ability to withstand thermal as well as mechanical shocks, and fast response time. However, their sensitivity is relatively low and they are susceptible to environmental disturbance signals and to the temperature drift of the preamplifier, making them unsuitable for measuring small temperature changes.
Thermocouples are usually used in harsh environments such as high temperatures, high vibration and shock, as well as for tiny structure temperature measurement occasions.
