Part I: 2-3
Oxygen Analyzer
Part I: Control Unit
The digital concentration signal—along with input from the control
panel—is processed by the microprocessor, and appropriate control signals
are directed to the display, alarms and communications port as well as to
the optional gas control valves in the Analysis Unit.
The same digital information is also sent to a 12 bit digital to analog
converter that produces the 0-1 V dc and the optional 4-20 mA dc analog
concentration signal outputs, and the analog range ID outputs.
The microprocessor monitors the power supply, and activates the
system failure alarm if a malfunction is detected.
2.3 Temperature Control
For accurate analysis this instrument is temperature controlled not to
fall beneath a certain temperature. This temperature is 22
o
F. This is to
prevent the sensor from freezing in cold environments.
