choosing a sensor INTRODUCTION The sensor detects the infrared radiation emitted by an area of the target surface, and converts this into a useful temperature measurement. There are 3 main factors affecting the accuracy of the measurement: TARGET SIZE AND DISTANCE AMBIENT CONDITIONS Most non-reflective materials, such as paper, cardboard, asphalt, food, plastics, rubber and painted surfaces are easy to measure with a general-purpose, longwavelength sensor. In normal room-temperature conditions, a simple, uncooled sensor may be used. For hotter environments, high-ambienttemperature models, or...
