DPM72 O2/C: Oxygen Analyzer
This unit uses a high-stability electro-chemical sensor with built in temperature compensation and a programmable display for controlling the concentration of oxygen in an enclosed compartment.
Day to day calibration is carried out from the front panel. All the calibration and alarm parameters are retained in a non-volatile memory.
PRINCIPLE OF OPERATION
Oxygen concentration is sensed and displayed on the controller, a programmable set point is used to select the required Oxygen level.
If the Oxygen concentration sensed by thye fuel cell is below the control set point value, the controller will operate to the solenoid valve for a user defined time period in the range of 0 to 255 seconds. After the injection period the solenoid valve will close for a further user defined time period in the range of 0 to 255 seconds, to allow for mixing. If the Oxygen level is still below the control set point, the cycle repeats until the required Oxygen is reached.
