Oxygen Analyzer

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

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 4-20 mA dc and the 0-1 V dc analog concentra-

tion 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.
