1 Introduction
The Smartec infrared sensor SMTIR9901 and SMTIR9902 are sophisticated full
silicon infrared sensors. The sensors can be used in measuring the radiation
temperature without any contact. For the different radiation temperature ranges various
filters are available. The sensor t*e SMTIR9902 contains a temperature sensor for
measuring the temperature of the sensor itself. The temperature range of the sensorelement
is between - 40 to 100 ºC. The sensor is available in a standard TO-05
encapsulation and with a 5.5. mm high p* filter.
2 T*ical applications
· Contactless measurement of surface temperatures or Infrared radiation
· temperature measurement on moving objects.
· Continuous temperature control of manufacturing.
· Thermal alarmsystems
· Climate control
· Medical instruments
· Home appliances.
Easy and accurate measuring of the sensors temperature by means of a built-in
temperature sensor(only for t*e SMTIR9902).
The main characteristics of the infrared sensor are:
· High accuracy
· High sensitivity (110 V/W)
· Low resistance (50 KW) and therefore
· Very good signal-to-noise-ratio
· Good response time (40 ms)
· Low cost thin film technology
