Manufacture: Azbil Corporation
Model: AUD700

The model AUD700 operates as a highly sensitive, adjustable ultraviolet flame detector. It monitors mono-fuel or multi-fuel oil and gas burners.

• This device features two sensitivity adjustment controls.
• The detector outputs a 0 to 35 V DC flame detection signal.
• This strong signal allows long wiring to the burner controller without needing special cables.
• A fused quartz glass lens protects the monitoring window.
• It actively blocks exhaust gas, soot, and hot air from entering the device.
• A built-in jack measures the flame detection signal.
• This feature simplifies the process of selecting the best flame monitoring position.

Summary

The model AUD700 is a highly sensitive, adjustable ultraviolet flame detector. It reliably monitors single-fuel and multi-fuel oil or gas burners.

• You can pair this device with the model AUR76H flame monitor containing a built-in amplifier.
• Alternatively, use the model R7476A amplifier with specific discontinued burner controllers.
• These compatible discontinued models include the R4075C, R4332A, R4332B, and R4334A.
• A built-in shutter interrupts the flame’s light about 75 times per minute.
• This mechanical action allows continuous testing of the internal flame detection circuits and the amplifier.
