Een zeer flexibele reeks nauwkeurige rookgas zuurstof analysers, speciaal ontwikkeld voor verbrandingsanalyse- en regeltoepassingen.

Categorie: Tag:


Door gebruik te maken van AMETEK’s beproefde zirkoniumoxide sensortechnologie, biedt de WDG-1200/1210-reeks ’s werelds eerste volledig geïntegreerde, stand-alone rookgaszuurstof analyser.

Door het unieke ontwerp kan de sensor worden verwijderd zonder de buitenste beschermbuis te demonteren. Dit betekent dat onderhoud eenvoudig ter plaatse kan worden uitgevoerd, waarbij alle onderdelen ter plaatse kunnen worden vervangen, waardoor kosten en uitvaltijd worden verminderd.

De WDG-1200/1210 biedt de mogelijkheid voor lokale bediening via een eenvoudige gebruikersinterface of met een afstandsbediening die beschikbaar is voor minder toegankelijke locaties. De geavanceerde communicatie-opties en mogelijkheden maken een eenvoudige integratie in fabriek en proces besturing mogelijk.

De WDG-1200/1210-reeks biedt de essentiële metingen voor verbrandingsefficiëntie, NOx-reductie, meting van overtollige lucht en verontreinigingsbeheersing in de koolwaterstofverwerkings-, industriële verwerkings- en energieopwekkingsindustrie.

De WDG-1200/1210-reeks is de baanbrekende serie rookgaszuurstofanalysatoren van AMETEK Land.

AMETEK Land – WDG 1200/1210 Flue Gas Oxygen Analysers




Using AMETEK’s industry-proven zirconium oxide sensor technology, the WDG-1200/1210 range provides the world’s first fully-integrated, standalone flue gas oxygen analysers. The user interface is mounted onto the probe, lowering installation costs.

The unique design allows the sensor assembly to be removed without disturbing the outer protection tube. This means maintenance can be carried out easily on-site, with all parts replaceable in the field, reducing costs and downtime.

The WDG-1200/1210 offers local control via the simple user interface attached to the probe, with a remote-control unit available for less accessible locations. Advanced communications options allow straightforward integration into plant control systems.

The WDG-1200/1210 range provides the essential measurements for combustion efficiency, NOx reduction, excess air measurement and pollution control applications in the hydrocarbon processing, industrial processing and power generation industries.

The inner tube structure, including the sensor assembly and heater, can be completely removed, leaving the outer protection tube in the process. This makes field service fast and easy, without the expensive downtime of a return-to-factory repair.

The user interface is mounted onto the probe for local control at the measurement location. For restricted or hostile locations, a remote-control unit is available. Both methods use simple push-button operation and a clear LED display for ease of use.

310 stainless steel probes for the WDG analysers are available in various lengths, with a range of mounting flange options to suit your process. A dust-protection filter at the end of the probe prevents fly ash damage to the sensor.

The WDG-1200/1210 range is AMETEK Land’s ground-breaking series of flue gas oxygen analysers.
