Gas Detection Sensor, type GDA, GDC, GDHC, GDHF, GDH
Design
The GD product range is designed in a very flexible
way with a mother PCB (Print Circuit Board) and an
interchangeable precalibrated sensor PCB.
The mother PCB is the same for all GD models
independent of the refrigerant or sensor
technology. On the mother PCB individual settings
(Alarm levels, delays e.t.c) can be set to meet local
legislation or application requirements.
The sensor PCB is always precalibrated and dedicated
to the actual refrigerant and ppm range. Danfoss has in
advance selected the most appropriate sensor making
it easy to optain safe detection and avoid false alarms
from other gases present.
Because of the interchangeable precalibrated
sensor PCB, it is very easy to replace the sensor
when service or a calibration procedure is required
(see the below drawings).
