Application
Tips: RTD sensor probe for air or object surface temperature measurement
Compared to the RTD sensor, thermocouples can operate at much higher temperatures and respond faster. However, the voltage signal generated by a thermocouple is low and may require additional amplification, which is a disadvantage in environments with high electrical noise. Unlike thermocouples, RTD sensors do not require reference points, ice baths, or temperature compensation circuits. RTD sensor has a very low thermal mass, so it provides true surface temperature measurement value and response times as fast as 50ms.
When using an RTD sensor probe to measure the air temperature of a pipeline, the front end of the air temperature probe must be perpendicular to the measured pipeline and fully contact the measured air. The contact surface between the surface RTD probe and the measured object must be flat, otherwise, the measurement result will be affected during the measurement.
