Test gas supply control for automatic calibration
Test gas supply
The test gas supply for automatic calibration can be started by means of the
gas module’s integral solenoid valves or via external solenoid valves.
Depending on the gas supply circuit and the number of analyzer modules
installed there are several layout possibilities for the test gas supply:
1 analyzer module, integral pneumatic module with 1 solenoid valve
To calibrate analyzer modules with simplified calibration procedures:
• Caldos27 with single-point calibration
• Magnos206 and Magnos28 with single-point calibration
• Limas11 IR, Limas21 UV, Limas21 HW with calibration cells
• Uras26 with calibration cells
• Oxygen sensor.
1 analyzer module, integral pneumatic module with 3 solenoid valves
To calibrate all analyzer modules that can be used with the pneumatic mod-
ule.
