Structural Characteristics Cylindrical explosion‑proof stainless‑steel housing assembly. Threaded process‑mount interface for combustion‑equipment observation port installation. Integrated sensor‑head and sealed electronic‑circuit unit. Explosion‑proof cable‑gland wiring port for field signal cable connection. High‑temperature‑resistant transparent optical lens assembly.
Working Principle Flame ultraviolet‑infrared radiation passes through optical lens and irradiates silicon‑carbide sensor chip. Optical radiation intensity is converted into weak electrical signal. Internal sealed circuit module processes raw signal into standard 4‑20 mA analog current and relay contact status signal. Flame‑intensity value and flame‑present contact status are transmitted to burner‑management controller for safety logic processing.
Installation Requirements Install at designated observation window position of combustion equipment. Align optical axis accurately toward flame combustion zone. Use certified explosion‑proof cable glands for field wiring. Adopt shielded twisted‑pair signal cable for signal transmission.
