Servomex now offers SIL 2 safety compliance for the 2222H transmitter unit of its Servotough OxyExact 2200 oxygen gas analyser.
A high-precision oxygen analyser designed for use in hazardous area installations, the OxyExact utilises Servomex’s patent field-proven, non-depleting Paramagnetic sensing technology for an accurate repeatable oxygen measurement.
Using a three-enclosure system to ensure safe operation, it measures enriched oxygen (up to 100% O2) in potentially flammable sample gases at pressures up to 45psia. This system dramatically reduces ongoing costs by removing the need for pre-sample drying.
Used in process control applications where high-temperature, high-performance oxygen measurements are required, the OxyExact is useful in a range of hydrocarbon processing applications including the production of ethylene oxide, propylene oxide, ethylene dichloride, and vinyl acetate monomer acid.
The oxygen gas analyser is configured as a central control unit configured with up to six transmitters for easy device interaction and set-up.
The 2222H is now assessed as being SIL 2 compliant for use in safety instrumented systems in respect of hardware integrity only, according to IEC 61508 part 2:2010. This means the OxyExact is certified for safe use in an even wider range of hazardous environments. The assessment covers the transmitter unit configured with or without the optional internal flow alarm feature.
