System Options
For systems with one or two Hazardous Area Oxymitter 5000 units per
combustion process, an optional SPS 4001B Single Probe Autocalibration
Sequencer can be used with each Hazardous Area Oxymitter 5000 to provide
automatic calibration gas sequencing. The sequencer performs
autocalibrations based on the CALIBRATION RECOMMENDED signal from
the Hazardous Area Oxymitter 5000, a timed interval set up in fieldbus, or
whenever a calibration request is initiated.
System Features
1. The CALIBRATION RECOMMENDED feature detects when the sensing
cell is likely out of limits. This may eliminate the need to calibrate on a
"time since last cal" basis.
2. The cell output voltage and sensitivity increase as the oxygen
concentration decreases.
