Overview of the gas analyzers
Measuring technology (analyzers)
The following analyzers are available for selection:
• Uras26 infrared photometer for the measurement of
infrared-active gas components e.g. CO, NO, SO
2
• Limas23 ultraviolet photometer for the measurement of
NO, NO
2
and SO
2
• Magnos206 oxygen analyzer for the measurement of
O
2
in process gas or in N
2
• ZO23 trace oxygen analyzer for the measurement of
O
2
in pure gases (N
2
, CO
2
, Ar)
• Caldos27 thermal conductivity analyzer for the measurement
of binary gas mixtures with different thermal conductivity e.g.
Ar in O
2
, H
2
in Ar, CH
4
in N
2
• Electrochemical oxygen sensor for the measurement of O
2
Magnos206 can also be used in combination with Uras26 or
Limas23.
ZO23 cannot be used in combination with one of the other
analyzers. Only one ZO23 can be installed in the gas analyzer.
Caldos27 can also be used in combination with Uras26.
The electrochemical oxygen sensor can only be used in combi-
nation with Uras26 or Limas23.
Each analyzer has one physical measurement range per sample
component. A section of the physical measurement range can be
mapped to the current output (analog output) by on-site configu-
ration.
Calibration is always executed in the physical measurement
range. The permissible measurement range limits are given by the
specification of the smallest and largest measurement ranges for
the individual analyzers.
A total of up to five measurement components can be measured
with one gas analyzer.
The performance characteristics of the analyzers have been
determined according to IEC 61207-1:2010 “Expression of per-
formance of gas analyzers – Part 1: General”. They are based on
N
2
as the associated gas. Compliance with these characteristics
when measuring other gas mixtures can only be assured if their
composition is known.
Calibration
Calibration can be performed automatically or manually. Auto-
matic calibration – for all sample components together – is
normally started on a cyclically time-controlled basis; it can also
be started by an external control signal or via the Modbus as
well as manually on the display and operator control unit of the
gas analyzer.
Normally, simplified calibration methods with the built-in calibra-
tion cells or the so-called single-point calibration are used for
automatic calibration. If calibration with test gases is required
the control of solenoid valves for switching on five test gases,
zero gas and sample gas via digital outputs can be configured.
Integral gas feed
The integral gas feed (optional in model EL3020) is available in
two versions. It includes
• either the solenoid valve, pump, coarse filter, capillary tube
and flow sensor modules
• or a flow sensor module.
Electrical interfaces
The electrical interfaces for the output of measured values and
communication with external systems include
• The integrated Ethernet-10 /100BASE-T interface (for configu-
ration, software update and QAL3 data transfer)
as well as the integrated I/O modules depending on the
functional range and order
• 2-way and 4-way analog output modules with two or four
analog outputs,
• Digital I/O module with four digital inputs and four digital
outputs,
• Modbus module with one RS485 and one RS232 interface,
• Profibus module with one RS485 and one MBP interface.
Housing design
The housing for the EL3020 gas analyzer model is designed as
19-inch housing with 3 height units and degree of protection
IP20.
The housing for the EL3040 gas analyzer model is designed as
wall-mount housing with degree of protection IP65.
QAL3 monitoring
QAL3 monitoring is available as an option in the gas analyzer.
It is used to fulfill the requirements according to EN 14181 for
storage and analysis of device adjustment data. The QAL3
monitoring option features the following functions:
• Automatic acquisition, verification and documentation of drift
und precision at zero and reference points
• Reporting via CUSUM and Shewhart control charts
• QAL3 data storage in the gas analyzer (maximum 1 year)
• QAL3 data display and read-out as well as parameter setting
via web browser
• Status messages on deviations beyond requirements
• Data export for further processing with spreadsheet programs
