1.1.3 System 3
This example, System 3, represents typical applications in large boilers and heating furnaces,
where there is a need to monitor and control oxygen concentration. The reference gas and
calibration-time span gas are (clean, dry) instrument air. Zero gas is supplied from a gas cylinder.
System 3 uses the ZR40H automatic calibration unit, with auto-switching of the calibration gas.
A “combustible gas detected” contact input turns off power to the heater. There’s also contact
output from the converter that can be used to operate a purge gas valve to supply air to the
sensor.
