Fireye 4-128-1 Firetron Cell 320735-701 The equal percentage characteristic compensatesThe Fireye 4 128 1 Firetron Cell is a high sensitivity cadmium sulfide photocell engineered exclusively for use with the Fireye 48PT1 lead sulfide infrared scanner. Designed for precise flame detection in industrial and commercial burner applications, this component monitors infrared radiation emitted by combustion. The 4 128 1 operates as a resistive element that decreases in resistance upon exposure to infrared energy, providing the primary signal
