Draeger PEX 3000 Flammable Gas Detector
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
