Focusing on fixed gas detection in water supply, wastewater and waste industry applications, the Draeger stand will feature a wide variety of fixed gas detection systems, transmitters and sensors for use with oxygen, toxic and flammable gases. Combining cost savings with the fast, safe and reliable detection of hydrogen sulphide, methane and oxygen depletion, the display will include long life sensors which increase calibration intervals to one year, as well as the latest in infra-red (IR sensor technology). As well as a traditional exhibition stand, Draeger will also be presenting a workshop on “SIL* and functional safety in gas detection systems†in the COGDEM workshop room at 12.00 on 10 November, 2010.
Ensuring the reliable detection of combustible gases and vapours, the Draeger PIR 3000 is a smart, explosion proof, infra-red (IR) gas transmitter. ATEX approved and designed to provide failsafe operation in any potentially explosive environment, it can be used in oxygen depleted atmospheres and is immune to poisons such as H2S. Lower in cost than traditional pellistor or catalytic bead detectors, IR technology is also more robust and stable. In addition, the increased accuracy of IR means that maintenance costs can be significantly reduced with traditional six- monthly calibration intervals being extended to one year. Together with an overall life expectancy of more than 15 years, this means that the PIR 3000 is able to dramatically reduce lifetime ownership costs.
Also on show will be the low cost, explosion proof Draeger Sensor IR. Specifically developed to allow existing pellistor or catalytic bead detectors of hydrocarbons to be replaced easily and quickly with an IR detector, this innovative sensor mimics the behaviour of the pellistor it has replaced. This means that users of pellistor or catalytic bead detectors from the majority of manufacturers can upgrade to the increased reliability, operating life and reduced maintenance costs offered by superior IR technology.
The Draeger stand will also highlight the Polytron 3000 and Polytron 7000 range of intelligent transmitters, together with the patented Draeger Sensor for toxic gases and oxygen. Sensors are pre-calibrated and are plug-and-play. Simply plug in the sensor and the detector is ready to use with no further intervention from the operator. Replacing a sensor is equally easy and, because of their large size and accuracy, the sensors offer a very long life, with calibration intervals of one year to further enhance the cost reducing benefits.
* The need for safe system design is placing more and more focus on Safety Integrity Level (SIL) Standards. This is particularly true in any application where there is a need to constantly monitor and detect explosive or toxic gases and vapours, as well as oxygen deficiency and/or enrichment.
