Key Features
- -40°C to 85°C operational temperature range, allows deployment in difficult industrial environments
- Can measure object temperatures between -40°C and 300°C
- A typical target object temperature accuracy of ±1°C, precision across its full measurement scale
- Noise equivalent temperature difference (NETD) of just 0.1K RMS at a 1Hz refresh rate, offers superior noise performance
- Unlike microbolometer solutions, this sensor does not need re-calibration to specific temperature requirements ensuring greater convenience and lowering operational expense
- Two different field of view (FoV) options – standard 55°x35° version and a 110°x75° wide angle version
- Supplied in a 4-pin TO39 package, with the compact dimensions lowering the overall cost of the thermal imaging system
- I2C compatible digital interface, simplifying integration
