High stability Infrared sensor IC enables fast, accurate temperature measurements in demanding environments
A common challenge for current high end thermometer guns is their sensitivity to fast temperature changes in their environment. A stabilization period of up to ½ hour in a new environment is often necessary to achieve accurate measurements. The new MLX90616ESF-HCA thermopile
sensor with integrated electronic stabilization function uses proprietary Melexis technology to reduce the stabilization period to less than half a minute.
The The MLX90616 is intended to be used in applications where the user places a lens in front of the sensor to adjust the FOV to his application. The sensor-lens combination temperature measurement must be calibrated by the customer. Melexis provides the necessary software to do this in a typical engineering or production environment.
Extreme temperature range
The MLX90616 has been specifically designed to measure high object temperatures with a maximum of 1030ºC. The MLX90616 is factory calibrated in a wide temperature range of -40 to 85˚C for the ambient temperature. For integration in thermometer guns it comes with an 8 to 12 micron optical filter. The integrated electronics will calculate the object temperature based on the internal temperature, the thermopile output and the calibration data stored in the EEPROM by the thermometer manufacturer during his calibration process.
Resolution
The calculated object and ambient temperatures are available from RAM memory with a resolution of 0.02 ˚C. They are accessible by a 2 wire serial SMBus compatible protocol (0.02°C resolution) or via 10-bit PWM (Pulse Width Modulated) output.
Package and availability
The sensor comes in an industry standard 4 pin TO-39 package. The MLX90616ESF-HCA is immediately available and pricing is set at 16$ per 100 pieces.
