Oxygen measurement with Ex approvals & SIL2 certification
The new Zirkor200 oxygen-measurement analyzer (photo) adds features for integration into safety-related process controls. The user-friendly, extremely rugged and precise zirconium-dioxide analyzers are not only available for gas explosion-hazardous areas (Zirkor200 Ex-G), but for use in dust explosive atmospheres (Zirkor200 Ex-D) as well. The Zirkor200 now also features SIL2 certification for integration into safety-related process controls. Both explosion-proof variants are approved in accordance with ATEX and IECEx. The Zirkor200 Ex-G for Zone 1 works well primarily in the chemicals, petrochemicals, refineries and oil-and-gas industries. With the Zirkor200 Ex-D for Zone 21, the focus is on applications in the cement and power-generation industries, and in the fields of waste-processing and recycling. In the majority of these industries, the Zirkor200 with SIL2 option also enables safety-relevant measurements with only one system (1oo1; one out of one). The analyzers of the Zirkor200 series handle process-gas temperatures up to 1,600°C. — SICK Inc., Minneapolis, Minn.
