Flame Sensor DPU for SA-GVK, SA-PNG, AB-1G, AB-2G Automation Systems

The indicator is equipped with a self-test system to exlude false signals. For this pupose the indicator is fitted with an electromagnetic shutter which recurrently closes and opens the optical channel. The shutter is controlled by the automation block. Output impulses with the shutter

When ionization radiation takes place the breakdown between electrodes occurs. The signal goes from DPU connector contact to flame control card input, which contains the second part of flame control channel .

Main Parameters and Dimensions

DPU translates UV flame radiation into an impulse electric signal. The UV detecting component of the sensor is an ion indicator, AC voltage 50 GHz is applied its electrodes via differentiating circuit.

Flame sensor DPU is used in control and security automation systems such as SA-GVK, SA-PNG, AB-1G, AB-2G.
