INFRARED SENSOR WITH SILICON LENS SMTIR9902SIL Typical Applications * Contactless measurement of surface temperatures * Temperature measurement of moving objects * Remote measurement due to small angle of view * Climate control * Medical instruments Introduction The Smartec infrared sensor type SMTIR9902SIL is a standard Smartec SMTIR9902 sensor equipped with a silicon lens for measuring radiation temperatures within a small angle of view (7.27'). The SMTIR9902SIL contains a NI1000 temperature sensor for measuring the temperature of the sensor itself. The temperature range of this internal sensor is -20 to 100 'C. The sensor is mounted in a modified TO-05 encapsulation.
