QRA2
Flame detector for use with Siemens burner controls, for the
supervision of gas flames and yellow- / 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- / 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
