Technical Description
3-2 Operating instructions ULTRAMAT 23 gas analyzer
C79000-B5276-C216-03
3.1 General
3.1.1 Overview
3.3
.1.1
The ULTRAMAT 23 gas analyzer can measure up to 4 gas com-
ponents at once: A maximum of three infrared sensitive gases
such as CO, CO
2
, NO, SO
2
, CH
4
plus O
2
with an electrochemi-
cal oxygen measuring cell.
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.

3.1.2 Benefits
• AUTOCAL with ambient air
(depends on measured component)
High efficiency so no calibration gas and accessories re-
quired
• High selectivity by multiple layer detectors, small cross sensi-
tivity e.g. to water vapor
• Easy to clean sample cells,
reduced maintenance cost
• Menu-assisted operation in plain text
operation control without manual, high operational safety
• Service information and log book,
preventive maintenance; help for service and maintenance
personnel, cost reduction
• Coded operator level against unauthorized access,
increased safety
• Open interface architecture (RS 485, RS 232; PROFIBUS,
SIPROM GA);
simplified process integration, remote control.
3.1.3 Applications
Application areas
• Optimization of small firing systems
• Monitoring of exhaust gas concentration from firing systems
with all types of fuel (oil, gas and coal) as well as operational
measurements with thermal incineration plants
• Room air monitoring
• Monitoring of air in fruit stores, greenhouses, fermenting cel-
lars and warehouses
• Monitoring of process control functions
• Atmosphere monitoring during heat treatment of steel
• For use in non-potentially explosive atmospheres.
Further applications
• Environmental protection
• Chemical plants
• Cement industry.
Special applications
The ULTRAMAT 23 with 2 IR components without pump is also
available with two separate gas paths. This allows the measure-
ment of two measuring points as used e.g. for the NO
x
measure-
ment before and after the NO
x
converter.
The ULTRAMAT 23 gas analyzer can be used in emission mea-
suring systems and for process and safety monitoring.
TÜV-approved versions of the ULTRAMAT 23 are available for
measurement of CO, NO, SO
2
and O
2
according to 13. BImSchV
27.BImSchV, 30.BImSchV (N
2
O) and TA Luft.
Smallest TÜV-approved and permitted measuring ranges:
• 1- and 2-component analyzer
- CO: 0 to 150 mg/m
3
- NO: 0 to 250 mg/m
3
- SO
2
: 0 to 400 mgm
3
• 3-component analyzer
- CO: 0 to 250 mg/m
3
- NO: 0 to 400 mg/m
3
- SO
2
: 0 to 400 mg/m

All larger measuring ranges are also permitted.
In addition, the TÜV-approved versions of the ULTRAMAT 23 ful-
fill the requirements according to EN 14956 and QAL 1 accord-
ing to EN 14181. Conformity of the analyzers with both standards
has been certified by the TÜV. The analyzer drift according to EN
14181 (QAL 3) can be carried out manually or by PC using the
SIPROM GA maintenance and servicing software. In addition,
certain manufacturers of emission evaluation computers offer
the possibility for reading the drift data out of the analyzer over
its serial interface and automatically logging and processing it in
the evaluation computer.
• Version with faster response time
The connection between the two condensation traps is provi-
ded with a plug so that the complete flow passes through the
measuring cell (otherwise only 1/3 of the flow), i.e. the re-
sponse time is 2/3 faster. All other components retain their
function.
• Chopper section purging: consumption 100 ml/min
(inlet pressure setting: ca. 3 000 hPa)
