Temperature transmitters are instruments that convert temperature signals into electrical signals using components such as RTDs. The development process of a temperature transmitter is complex and demanding, and many factors influence the measurement of the final temperature transmitter. Thermal inertia is one of these important factors. Thermal inertia refers to the property of how quickly the temperature of the surface of a material changes when a certain amount of heat is added to the material at a certain time. The thermal inertia of a temperature transmitter is actually the thermal inertia of the RTD or thermocouple in the temperature transmitter. Due to the thermal inertia of the RTD or thermocouple so that the instrument’s indication value lags behind the change in temperature of the measured medium, this effect is particularly prominent in the rapid measurement. The solution to this phenomenon is usually used to solve the usual practice of good thermal conductivity of the material, thin-walled, small inner diameter of the temperature probe and protection sleeve. Star Instruments production temperature transmitter probe and protection sleeve for 304 or 316L stainless steel material, excellent thermal conductivity. The diameter of the probe of the temperature transmitter is 6mm, the diameter of the protective sleeve is 10mm, the response speed of the temperature transmitter without sleeve is 10s, and the response speed of the temperature transmitter with sleeve is 55s, if you still need to improve the response speed of the temperature transmitter, you can add the heat-conducting medium in the sleeve. Temperature transmitter thermal inertia caused by the error in the measurement has a great impact, especially in the precision measurement must pay attention to, we should try to avoid the temperature transmitter thermal inertia caused by the error, or to take appropriate compensation to weaken the error.
