QRA2
Flame detector for use with Siemens burner controls, for the
supervision of gas flames and yellow- or blue-burning oil
flames as well as ignition spark checking. Plastic housing,
metalized to prevent static charging caused by the air flow
from the fan. For direct mounting on the burner. The
detectors can be supplied with or without securing flange
and clamp.
See Data Sheet N7712.
QRA4
Flame detector for use with Siemens burner controls, for the
supervision of gas flames and yellow- or blue-burning oil
flames as well as for ignition spark proving.
See Data Sheet N7711.
QRA10
Flame detector for use with Siemens burner controls, for the
supervision of gas flames and yellow- or blue-burning oil
flames as well as ignition spark checking. Die-cast aluminum
housing with a 1 in. mounting coupling and connection
facility for cooling air. The housing of this detector has a
bayonet fitting which allows it to be secured either directly to
the 1 in. mounting coupling or to the AGG06. The 1 in.
mounting coupling can be screwed to a viewing tube or to
the AGG07. The Pg cable gland can be removed and
replaced, if some other detector cable shall be used.
See Data Sheet N7712.
QRB1
Photo resistive flame detector for use with Siemens burner
controls, for the supervision of oil flames in the visible light
spectrum. Especially suited for use with burner controls for
small capacity burners in intermittent operation.
See Data Sheet N7714
QRB3
Photo resistive flame detector for use with Siemens burner
controls, for the supervision of oil flames in the visible light
spectrum. Especially suited for use with burner controls for
small capacity burners in intermittent operation.
See Data Sheet N7714.
QRB4
Yellow flame detector for use with Siemens burner controls,
for the supervision of oil flames in the visible light spectrum.
The QRB4 is used in connection with oil burner controls in
intermittent operation.
Refer to data sheet N7720.
