Continuous Gas Analyzers, extractive
ULTRAMAT 23
General information
■ Overview
Up to four gas components can be measured simultaneously
with the ULTRAMAT 23 gas analyzer: up to three infrared-active
gases such as CO, CO2, NO, SO2, CH4, plus O2 with an electrochemical oxygen sensor.
ULTRAMAT 23 basic versions for:
• 1 infrared gas component with/without oxygen measurement
• 2 infrared gas components with/without oxygen measurement
• 3 infrared gas components with/without oxygen measurement
• With the ULTRAMAT 23 gas analyzer for use in biogas plants,
up to four gas components can be measured continuously:
two infrared-sensitive gases (CO2 and CH4), plus O2 and H2S
with electrochemical measuring cells.
• With the ULTRAMAT 23 gas analyzer with paramagnetic
oxygen cell, up to four gas components can be measured
continuously: three infrared-active gases, plus O2 ("dumbbell"
measuring cell).
■ Benefits
• AUTOCAL with ambient air (dependent on the measured
component)
Highly cost effective because calibration gases are not
required
• High selectivity thanks to multi-layer detectors, e.g. low
cross-sensitivity to water vapor
• Sample chambers can be cleaned as required on site
Cost savings due to reuse after contamination
• Menu-assisted operation in plaintext
Operator control without manual, high level of operator safety
• Service information and logbook
Preventive maintenance; help for service and maintenance
personnel, cost savings
• Coded operator level against unauthorized access
Increased safety
• Open interface architecture (RS 485, RS 232, PROFIBUS,
SIPROM GA)
• Simplified process integration; remote operation and control
Special benefits when used in biogas plants
• Continuous measurement of all four important components,
including H2S
• Long service life of the H2S sensor even at increased concentrations; no diluting or backflushing necessary
• Introduction and measurement of flammable gases as
occurring in biogas plants (e.g. 70 % CH4), is permissible
