QFC/QFCE/QFCK Pyroelectric Infrared Flame Sensors

KEMET’s QFCE pyroelectric flame sensors combine high sensitivity with fast response times and high dynamic range to ensure rapid and accurate detection of small and large flames, nearby or over larger distances. These high quality sensors, in their industry standard TO-39 package, integrate a digital, current mode read-out offering high responsivity over the full frequency range of flame flicker from 3 - 30 Hz. Industry standard I2C communication enables plug-and-play connectivity to microcontrollers and allows easy tuning and calibration. Programmable gain and filtering offer maximum flexibility in system design. Their long and maintenance-free operational lifetime and various low power modes make these sensors ideal for any smart or IoT type of applications.

KEMET’s QFC pyroelectric flame sensors provide accurate discrimination of flame sources in triple IR flame detection systems, through their excellent signal to noise characteristic at the signature 8 – 10 Hz flicker range of a flame. The sensor element is built into a low noise circuit that has an internal CMOS op amp with a 10 GΩ feedback resistor outputting a voltage signal centred around half the supply rail. Exceptionally high responsivity, a wide field of view and rapid recovery from thermal and electrical shocks makes it the ideal solution for demanding flame detection applications.
