sensor solutions ///tpt300v page 1 10 /2015 tpt300v ir pyrometer key features ? contactless temperature measurement ? high accuracy ? wide temperature range ? digital and analogue interface ? industrial usage (ip65) tpt300v is a contactless temperature measuring system - called pyrometer - based on the detection of infrared radiation. tpt300v is equipped with a lens and an infrared sensor (thermopile) in front. it has to be pointed at the target object. the basic working principle is: ? detection of infrared radiation with a thermopile sensor ? further analogue signal processing ? calculation of the objects temperature using a microcontroller ? providing the objects temperature at digital or analogue output the main fields of applications are temperature measuring in industrial applications i.e. at moving or inaccessible parts
