Product Description

INFRARED SENSORS SMTIR9901/02

SMTIR9901/02 Infrared Temperature Sensor Typical applications
• Contactless measurement of surface temperatures or infrared radiation
• Temperature measurement on moving objects
• Continuous temperature control of manufacturing
• Thermal alarm systems
• Climate control
• Medical instruments
• Home appliances

SMTIR9901/02 Infrared Temperature Sensor Features
• High accuracy
• High sensitivity (110 V/W)
• Low resistance (50 KΩ) and therefore
• Very good signal-to-noise-ratio
• Good response time (40 ms)
• Low cost thin film technology

SMTIR9901/02 Infrared Temperature Sensor Introduction
The Smartec infrared sensors SMTIR9901 and SMTIR9902 are sophisticated full silicon infrared sensors which can be used in measuring the radiation temperature without any contact. For the 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 ºC. The sensor is available in a standard TO-05 encapsulation and with a 5.5. µm. high pass filter.

Easy and accurate measuring of the sensors temperature by means of a built-in temperature sensor (only for type SMTIR9902).
