PRODUCT DESCRIPTION
The Smartec infrared sensors SMTIR99XX are sophisticated full silicon infrared sensors and comprise of so called thermopiles. Thermopiles are based on the Seebeck effect, which is a long time standard for conventional thermocouples. The application of thin film technology allows the production of miniaturised and low cost sensor elements. For specific applications there is a version with a small openings angle (7°).
The sensors can be used in measuring the radiation temperature without any contact. For different radiation temperature ranges various filters are available. The sensor type SMTIR9902 contains a temperature sensor for measuring the temperature of the sensor itself. The temperature range of the sensor-element is between -40 to 100 °C. The sensor is available in a standard TO-05 encapsulation and is equipped with a 5.5 micrometer filter. For small field of view there is an infrared sensor available with a silicon lens.
