IRD 1020
Flame detection device for
oil and gas flames
INTRODUCTION
The IRD 1020 detector is used to supervise gas or oil flames.
This flame monitoring device should be connected to a
Satronic oil burner control box. Monitoring is based on the
infra-red flicker principle, in other words, the flickering infra-
red light of the flame is detected. The steady radiation from,
for example, the glowing refractory layer on the inside of the
boiler, has no effect on the detector. The IRD 1020 replaces
the IRD 920. When exchanging the units, care must be taken
to wire them correctly.

CONSTRUCTIONAL FEATURES
The infra-red sensor and the pre-amplifier are hermetically
sealed in glass and along with the electronics form an
integrated unit in the flame detector. Wiring is by way of a
plug connection. The sensitivity control and two LED’s for
indication of the flame signal are situated on the rear of the
flicker detector.
