Selecting the right temperature sensor

摘要

CAL SWANSON OF WATLOW LOOKS AT OPTIMAL TEMPERATURE SENSOR SELECTION, YOUR FIRST STEP TO ACHIEVING ACCURATE TEMPERATURE MEASUREMENT. There's no simple solution to achieving accurate temperature measurement. It's a combination of knowing the inherent accuracy of particular sensor types, but also how environmental factors can create further measurement uncertainty and the sensor calibration techniques available to reduce this uncertainty. A basic awareness of the inherent accuracy of particular sensor types is important, but goes only a short way toward the goal of achieving optimally accurate temperature measurement. It is the broader knowledge of how sensor choice, sensor placement and a wide variety of environmental factors can contribute to sensor error, as well as having a familiarity with calibration techniques that can be used to reduce this uncertainty, that ultimately leads to optimum sensor selection and measurement accuracy.
