The transmitter Draeger PEX 3000 detects flammable gases and vapours in concentrations below their lower explosive limit (100 %LEL). It increases the explosion protection of your plant. Its catalytic bead sensor provides a long-term stable measuring signal and responds to gas within a few seconds.
• Six variants of transmitters
• Simple installation
• One-man Calibration
• Explosion Protection
• Low gas concentrations
• The catalytic bead sensor
• Oil refineries/mining/OnShore/Off Shore /Tank Farms/Water treatment plants
• Continous monitoring of Hydrocarbon , Hydrogen Flammable Gases using Catalytic technology without Display or any indication
• Normal measurment possible with 4-20mA
• Hazardous area Application (zone 1,Zone2)
• Continous monitoring of Hygrogen in battery rooms
