BARTEC EEx p control unit "Leakage compensation"

The APEX 2003.SI/A2 control unit controls and monitors the prepurging and operating phases of gas analyzers with containment systems in hazardous zone 1.

The control unit redundantly monitors the set overpressure of the purging gas. When the overpressure decreases, it is corrected to the adjustable setpoint (max. purging gas pressure 165 hPa).
