TEMPERATUREAccurate Measurementsin Extreme EnvironmentsMLX90616 for extreme contact-less temperature solutionsProduct OverviewA common challenge for current high end thermometerguns is sensitivity to fast temperature changes in theirenvironment. A stabilization period of up to a half hour in theenvironment is often necessary to achieve new, accurate,measurements. The new MLX90616ESF-HCA thermopilesensor with integrated electronic stabilization function usesproprietary Melexis technology to reduce the stabilizationperiod to less than one minute.The MLX90616ESF-HCA incorporates a secondarythermopile sensor to detect temperature variations in thepackage and in the optical assembly. The signal of thissecondary sensor is used to compensate electronicallyfor the adverse effect on the measurement. In this way itis possible to make a thermometer gun which stabilizes inseconds and gives accurate results in extreme, demandingenvironments.The MLX90616 is intended to be used in applications wherethe user places a lens in front of the sensor to adjust the FOVto his application. The sensor-lens combination temperaturemeasurement must be calibrated by the customer. Melexisprovides the necessary software to do this in a typicalengineering environment.ResolutionThe calculated object and ambient temperatures areavailable from RAM memory with a resolution of 0.02 ˚C.They are accessible by a 2 wire serial SMBus compatibleprotocol (0.02°C resolution) or via 10-bit PWM (Pulse WidthModulated) output.Features & BenefitsEasy to integrateFactory calibrated in wide temperature range:-40…+85ºC for sensor temperatureMeasurement range -70ºC to 1030ºCMeasurement resolution of 0.02ºCBuilt-in thermal gradient compensation sensor for faststable readingsSMBus compatible digital interfaceCustomizable PWM output for continuous reading3V supply voltageSleep mode for reduced power consumption8-14um spectral sensitivityTEMPERATUREExtreme Temperature RangeThe MLX90616 has been specifically designed to measurehigh object temperatures with a maximum of 1030ºC.The MLX90616 is factory calibrated in a wide temperaturerange of -40 to 85ºC for the ambient temperature. Forintegration in thermometer guns it comes with an 8 to 12micron optical filter. The internal electronics will calculatethe object temperature based on the internal temperature,the thermopile output and the calibration data stored inthe EEPROM by the thermometer manufacturer during thecalibration process.103www.FutureElectronics.com/Sensors
