Continuous Gas Analyzers, extractive
ULTRAMAT/OXYMAT 6
General information
■ Overview
■ Application
Fields of application
• Measurement for boiler control in incineration plants
• Emission measurements in incineration plants
• Measurement in the automotive industry (test benches)
• Process gas concentrations in chemical plants
• Trace measurements in pure gas processes
• Environmental protection
• TLV (Threshold Limit Value) monitoring at places of work
• Quality monitoring
The ULTRAMAT/OXYMAT 6 gas analyzer is a practical combination of the ULTRAMAT 6 and OXYMAT 6 analyzers in a single enclosure.
The ULTRAMAT 6 channel operates according to the NDIR twobeam alternating light principle and measures one or two gases
highly selectively whose absorption bands lie in the infrared
wavelength range from 2 to 9 μm, such as CO, CO2, NO, SO2,
NH3, H2O as well as CH4 and other hydrocarbons.
The OXYMAT 6 channel is based on the paramagnetic alternating pressure method and is used to measure oxygen in gases.
■ Benefits
• Corrosion-resistant materials in gas path (option)
- Measurement possible in highly corrosive sample gases
• Sample chambers can be cleaned as required on site
- Cost savings due to reuse after contamination
• Open interface architecture (RS 485, RS 232, PROFIBUS)
• SIPROM GA network for maintenance and servicing information (option)
ULTRAMAT channel
• High selectivity with double-layer detector and optical coupler
- Reliable measurements even in complex gas mixtures
• Low detection limits
- Measurements with low concentrations
OXYMAT channel
• 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 to measure corrosive gases
- 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
Special versions
• Special applications
Besides the standard combinations, special applications concerning material in the gas path, material in the sample cells
(e.g. Titan, Hastelloy C22) and sample components are also
available on request.
• TÜV version/QAL
TÜV-approved versions of the ULTRAMAT/OXYMAT 6 are
available for measurement of CO, NO, SO2 and O2 according
to 13th and 17th BlmSchV and TA Luft.
Smallest TÜV-approved and permitted measuring ranges:
- 1-component analyzer
CO: 0 to 50 mg/m3
NO: 0 to 100 mg/m3
SO2: 0 to 75 mg/m3
- 2-component analyzer (series connection)
CO: 0 to 75 mg/m3
NO: 0 to 200 mg/m3
All larger measuring ranges are also approved.
Furthermore, the TÜV-approved versions of the
ULTRAMAT/OXYMAT 6 comply with the requirements of
EN 14956 and QAL 1 according to EN 14181. Conformity of the
devices with both standards is TÜV-certified.
Determination of the analyzer drift according to EN 14181
(QAL 3) can be carried out manually or also with a PC using the
SIPROM GA maintenance and servicing software. In addition,
selected manufacturers of emission evaluation computers offer
the possibility for downloading the drift data via the analyzer’s
serial interface and to automatically record and process it in the
evaluation computer.
• Flow-type reference compartment
- The flow through the reference compartment should be
adapted to the sample gas flow
- The gas supply of the reduced flow-type reference
compartment should have an upstream pressure of 3 000 to
5 000 hPa (abs.). Then a restrictor will automatically adjust
the flow to approximately 8 hPa
■ Design
19" rack unit
• 19" rack unit with 4 HU for installation
- in hinged frame
- in cabinets with or without telescopic rails
• Front plate can be swung down for servicing purposes
(laptop connection)
• Internal gas paths: hose made of FKM (Viton) or pipe made of
titanium or stainless steel
• Gas connections for sample gas inlet and outlet: pipe diameter 6 mm or 1/4"
• Flow indicator for sample gas on front plate (option)
• Sample chamber (OXYMAT channel) – with or without flowtype compensation branch – made of stainless steel (mat. no.
1.4571) or of tantalum for highly corrosive sample gases
(e.g. HCl, Cl2, SO2, SO3, etc.)
• Monitoring (option) of sample gas and/or reference gas
(both channels)
