ePR44xx2 (TO) - (Rev. 1.1) PRELIMINARY 2 ezPyro TO I C Pyroelectric Infrared Flame Sensor Introduction The ezPyro range of thin film digital pyroelectric sensors for flame detection combines high quality sensors with a high level of configurable electronic integration in an industry standard TO-39 package. High sensitivity combined with fast response times ensure rapid and accurate flame detection. The high dynamic range allows detection of small and large flames, nearby or over larger distances. These sensors integrate a digital, current mode read-out offering high responsivity over the full frequency range of flame flicker (3-30 Hz). Programmable gain and filtering offer maximum flexibility in system design. Industry 2 standard I C communication enables plug-and-play connectivity to microcontrollers and allows easy tuning and calibration. Pyreos sensors are very stable over time ensuring a long and maintenance-free operational lifespan. Various optical filter options are available. These sensors can also be daisy-chained to allow synchronized sampling across devices and offer various low power modes.
