/IR3 point infrared flame detector (hereinafter referred to as IR3 flame detector) is a small high-performance flame detector designed according to the market demand and customer's suggestions on the basis of referring to our previous flame detectors. IR3 flame detector uses a new type of narrow-band current-type infrared pyroelectric sensor, with a built-in 32-bit microprocessor and a patented (CN202010297486.5) signal processing algorithm, which can quickly identify the flame signal, accurately distinguish the real flame from the interference source, and greatly reduce the impact of environmental factors on the detector. Meet the explosion-proof, protection, corrosion resistance and other properties, while IR3 flame detector is smaller, lighter and more convenient to install.
