15 Dräger Infrared vs. heat of reaction technology
Catalytic bead sensor Infrared sensor Used in Dräger Measuring principle By means of infrared light in a specific wave length the C-H bond of Hydrocarbon molecules will oscillate, whereas the infrared light will lose energy (light will be absorbed by the gas). In principle, the gas detectors will measure how much the light sent from the infrared lamp will be absorbed during the multiple passing through the gas. Colour filter in front of each detector will let pass only a small frequency range of light. The measuring detector has been tuned to the specific absorption of the C-H stimulation. The reference detector will measure the general light intensity. By comparison of both measurements a reliable result will be shown, which is largely independent to aging processes. Heat of reaction sensors are based on the oxidation of flammable gases on the surface of electrical heated catalytic elements, the pellistor. Due to the emerging heat of combustion the electrical resistance of the pellistor changes. The electrical homogenous compensator (the inactive spiral coil) is covered with a chemical inert layer and is used as a reference resistance to the pellistor. The resulting resistance change in the active part will be altered into a output signal. Direct Reading Seminar | Marketing |

16 Dräger Infrared vs. CatEx – metrological differences
Catalytic bead sensor Infrared sensor Inert Measurement: O2 in gas sample required?  for the operation at least 10% O2 is required.  also applicable in inert atmospheres Typical measuring ranges for flammable gases % LEL flammable gases Vol.-% for Methane % LEL flammable Hydrocarbons Vol.-% for Methane, Propane and Ethylene Measureable flammable gases All flammable gases; exception: large molecules No influence by non flammable gases All flammable Hydrocarbons with C-H bonds No measurement of Hydrogen (H2);  but a combination of the IR Ex sensor with the electrochemical H2 sensor to an added H2 Ex signal is possible.

18 Dräger Infrared vs. heat of reaction technology
Catalytic bead sensor Infrared sensor “Fail Safe“ Some faults like contaminations, can only be discovered by a bump test Possible sensor defects like corrosions on the surface, defective lamps or detectors can be shown by the instrument as an error Limitations and erratic influences (e.g. contamination) Silicones; halogenated Hydrocarbons; lead-containing components as Tetraethyl lead; Organic Phosphorous compounds; Sulphur compounds high concentrations (H2S)- the CatEx 125 used in the Dräger X-am 5000 is equipped with an H2S pre filter to reduce the influences No influences by sensor poisoning Minimized influences due to water vapor concentration In the Dräger X-am 5600 this influences will be minimized by heating the measuring cell (avoid condensation).

21 Dräger X-zone 5000 Technology Update
August 2012, Russell Warn

22 Portable Gas Detection Portfolio Application overview
Dräger Sensoren A small sensor - a giant step into the future: The new DrägerSensor XXS is remarkably compact, and boasts an even higher performance than the competition. Compact and powerful: The durable Dräger infrared sensors work very accurately and precisely, even in oxygen-free atmospheres. Multiple gases at the same time: The DrägerSensor Cat Ex measures combustible gases and vapors in the air.

23 Dräger X-zone 5000 Patented: Device Integrated in Amplifier
The product State-of-the-art area monitoring – the Dräger X-zone in combination with the Dräger X-am 5000 or X-am 5600 gas detection instruments can be used for the measurement of one to six gases. The transportable, sturdy and waterproof unit extends mobile gas detection technology to a unique system with many flexible applications

24 Area Monitoring - the concept Advantages of an area monitoring safety concept
Big savings by implementing an area monitoring safety concept! Example 1: Use of one area monitor instead of multiple personal gas monitors; Savings due to eased logistics and training efforts for contractors within industrial shutdowns => reduced costs Example 2: An area monitor is placed where the gas hazard is expected => more safety It can be used additionally to the personal air monitors handed out to all workers; Rerelease procedures e.g. „after lunch breaks“ can be eased. => less costs

25 Dräger X-zone 5000 Really noisy innovative area monitoring – 360°
Good sound! 108 dB at 1 m or 120 dB at 30 cm Sweeping alarm sound from 1500 to 2300 Hz, that cannot be missed even with different industrial background noises 360° visible green LED illuminated ring indicates: “no potential gas hazard” 360° visible red or red/green LED illuminated ring indicates: “gas hazard” in combination with a 360° audible evacuations alarm

26 Dräger X-zone 5000 Innovative area monitoring – 360°
360° gas access The 360° gas access on the top of the Dräger X-zone acts as a wind shield => highest safety

27 Dräger X-zone 5000 wireless fence line monitoring
Up to 25 Dräger X-zone 5000 units automatically interconnect to form a wireless fenceline. This interconnection of the transportable measuring heads enables quick monitoring of large areas, e.g. pipelines or industrial tanks within the scope of industrial shutdowns. If a unit indicates a gas alarm (mother alarm – red) the device transmits the alarms to all other units that are part of the fenceline to a daughter alarm – green/red thus ensuring a simple evacuation alarm. Alternatively a wired or a combination of a wired/wireless fenceline can also be formed. Wireless Alarm transfer from one instrument to the next => quick setup of a wireless fenceline reduces efforts for the construction site “safety preparation”

28 Gas Dispersion Where to place an area monitor?
Place an area monitor, where the gas hazard is expected, but where do you expect it? Hydrogen Methane Ammonia Acetylene Nitrogen Gas lighter than air: light gas or hot gases Depending on the gas type to be detected use socket Gas heavier than air: dense gas or cold Gases All chemicals have a different weight due to their composition. Gases and vapors can be sorted by their specific weight or density. The density of gases form two groups. One group lighter than air called buoyant gases and one group heavier than air call dense gas. If a gas is called buoyant and the dispersion is not disturbed, it will rise into the air. If a gas belongs to the group of dense gases it will move on the ground. As always in life there are exception to be considered behaving the opposite way. If temperature or pressure is involved substances might show different behavior at least for a period of time until they equilibrate with the environmental conditions. If liquefied substances leak they might first form a puddle which evaporated over time. Leaking Gas jets can point in all direction and show no specific behavior. Oxygen Carbon dioxide Propane Chlorine Benzene Phosgene

29 Dräger X-zone 5000 wireless fence line monitoring
Typical recommendation Comparable to fixed gas detectors – X-zones shall be placed, depending on expected gases, in a distance of <25 m to ensure a safe area monitoring system Technical capability X-zones would interconnect wireless at a distance of up to 100 m With the used frequency of 868 MHz (Europe) or 915 MHz (Australia, USA, Canada) a good connection also “around the corner” or with obstructions in-between the X-zones can be ensured even though the distance might be reduced

30 Dräger X-zone 5000 wireless fence line monitoring
Easy Setup within a MESH Network X-zones are automatically interconnected – the connection LED shows green, if a neighbour instrument is found; it shows red with no neighbour ALL DEVICES SPEAK TO ALL OTHER X-ZONES IN MINIMUM ONE OTHER NEIGHBOUR NEEDS TO BE FOUND TO TAKE PART IN THE COMMUNICATION OF THE WHOLE GROUP => HIGHEST SAFETY TO KEEP THE CONNECTION WITHIN THE FENCELINE left instrument switched on connection LED red right instrument turned on connection LED turned green

31 Dräger X-zone 5000 Pumped Area Monitoring
An integrated pump – available as an option – provides continuous monitoring of areas in pumped operation. Thus the system allows for continuous monitoring of difficult to access areas or confined spaces from a distance of up to 45 m. By using the diffusion cap the X-zone 5000 with pump is also useable in the diffusion mode.

32 Dräger X-zone 5000 Zone 0 In contrast to personal gas detection
instruments area monitors remain in the Ex area also in the event of a gas alarm. Therefore it is more important that they are approved for Ex zone 0 – continuous operation in explosive atmospheres is ensured. ATEX: I M1 Ex ia I Ma (Mining) II 1G Ex ia IIC T3 Ga (Industry – Zone 0) IECEx: II 2G Ex d ia T4 Gb CUS: Class I, Zone 0, AEx ia IIC T3 Ga Class I, Zone 1, AEx ia d IIC T4 Gb

33 Alternatively use the attractive X-am 5000/5600 maintenance tools:
Dräger X-zone 5000 Alternatively use the attractive X-am 5000/5600 maintenance tools: However, the gas detection instruments can also be quickly removed from the Dräger X-zone 5000 to allow usage of the accessories of the small personal gas detectors, such as the Dräger Bumptest Station or the Dräger E-Cal station. No daily Bumptest required! A bumptest is only necessary when placing the instrument on the site. With 5 days runtime this may be just one time a week! Dräger Bumptest Station, for bumptests and calibrations of the gas detection devices Dräger X-am 5x00 Dräger E-Cal Station, for bumptests, calibrations, configurations, fleet management of the gas detection devices
