General information
Special versions

■ Overview

Special applications
Besides the standard combinations, special applications concerning the material in the gas path and the material in the sample chambers are also available on request.
TÜV version QAL
As a reference variable for emission measurements according to
TA-Luft, 13th and 17th BlmSchV

■ Design

The function of the OXYMAT 6 gas analyzers is based on the
paramagnetic alternating pressure method and are used to
measure oxygen in gases.

■ Benefits
• Paramagnetic alternating pressure principle
- Small measuring ranges (0 to 0.5 % or 99.5 to 100 % O2)
- Absolute linearity
• Detector element has no contact with the sample gas
- Can be used under harsh conditions
- Long service life
• Physically suppressed zero through suitable selection of
reference gas (air or O2), e.g. 98 to 100 % O2 for purity monitoring/air separation
• Open interface architecture (RS 485, RS 232, PROFIBUS)
• SIPROM GA network for maintenance and service information
(option)
• Electronics and physics: gas-tight isolation, purging is possible, IP65, long service life even in harsh environments (field
device only)
• Heated versions (option), use also in presence of gases condensing at low temperature (field device only)
• EEx(p) for zones 1 and 2 according to ATEX 2G and ATEX 3G
(field device only)

■ Application
Fields of application
• For boiler control in incineration plants
• For safety-relevant applications (SIL)
• In the automotive industry (testbed systems)
• In chemical plants
• For ultra-pure gas quality monitoring
• Environmental protection
• Quality monitoring
• Versions for analyzing flammable and non-flammable gases
or vapors for use in hazardous areas
