Description
The DURAG Hegwein D-IO 55-10 Ionisation Flame Monitor is an important device for monitoring the flame status in combustion equipment. It utilizes a metallic ionization electrode that needs to be immersed in the flame.
DURAG Hegwein D-IO 55-11 Ionisation Flame Monitor, Intermittent operation
The burning flame forms an electrically conductive connection between the ionization electrode and the burner or ignition burner mechanism, and the conductive flame acts as a rectifier for the ionization current. The flame monitor measures this ionization direct – current signal to determine whether the flame is present.
The alternative model, the AAL76 series flame monitor, is a simple, versatile, and universal ionization flame monitor suitable for a wide range of combustion systems.
According to IEC/EN 60715, it can be simply installed on a 35mm rail. the AAL76 series flame monitor has a configurable safety time (ffdt), which can be set to 1s, 3s, or 5s. The supply voltage can be 115V, 125V, 230V, or 250V AC. Its output signal includes 90 – 110VDC, SPDT contact, and an optional 4 – 20mA signal.
the AAL76 series of flame monitors is suitable for gas and oil combustion applications, and can be used in industrial combustion plants, thermal processes, combustion chambers, boilers, furnaces, reactors, and other equipment. It can monitor gas and oil burners as well as gas and oil igniters under any load, and is applicable to both continuous and intermittent operation modes.
