General information
Special versions
■ Overview
Special applications
In addition to the standard combinations, special applications
are also available upon request (e.g. higher sample gas pressure up to 2 000 hPa absolute).
■ Design
19" rack unit

CALOMAT 6
General information
■ Function
Principle of operation
The measuring principle is based on the different thermal conductivity of gases.
The CALOMAT 6 works with a micromechanically produced
Si chip whose measuring membrane is equipped with thin-film
resistors.
The resistors are kept at a constant temperature. This requires
an current intensity depending on the thermal conductivity of the
sample gas. This "raw value" is processed further electronically
to calculate the gas concentration.
The sensor is located in a thermostatically-controlled stainless
steel enclosure in order to prevent the influence of changes in
ambient temperature.
To prevent the influence of changes in flow, the sensor is positioned in a bore located to the side of the main flow.
Note
The sample gases must be fed into the analyzers free of dust.
Condensation (dew point sample gas < ambient temperature) is
to be avoided in the measurement chambers. Therefore, the use
of gas modified for the measuring tasks is necessary in most application cases.

Sample
gas
• Two control levels with their own authorization codes for the
prevention of accidental and unauthorized operator interventions
• Simple handling using a numerical membrane keyboard and
operator prompting
• Customer-specific analyzer options such as:
- Customer acceptance
- TAG labels
- Drift recording
- Clean for O2 service
Measuring spans
The smallest and largest possible spans depend on both the
measured component (type of gas) and the respective application.
The smallest possible spans listed below refer to N2 as the residual gas. With other gases which have a larger/smaller thermal
conductivity than N2, the smallest possible span is also
larger/smaller.
Component
Smallest possible span
H2
0 ... 1 % (95 ... 100 %)
He
0 ... 2 %
Ar
0 ... 10 %
CO2
0 ... 20 %
CH4
0 ... 15 %
H2 in blast furnace gas
0 ... 10 %
H2 in converter gas
0 ... 20 %
H2 with wood gasification
0 ... 30 %
Influence of interfering gases
Knowledge of the sample gas composition is necessary to determine the influence of residual gases with several interfering
components.
CALOMAT, principle of operation
Essential characteristics
• Four freely parameterizable measuring ranges, also with suppressed zero point, all measuring ranges linear
• Smallest measuring spans up to 1 % H2 (with disabled zero
point: 95 to 100 % H2) possible
• Measuring range identification
• Galvanically isolated measured-value output 0/2/4 to 20 mA
(also inverted)
• Autoranging or manual measurement range switchover possible; remote switching is also possible
• Storage of measured values possible during adjustments
• Wide range of selectable time constants (static/dynamic noise
suppression); i.e. the response time of the analyzer can be
matched to the respective measuring task
• Short response time
• Low long-term drift
• Measuring point switchover for up to 6 measuring points
(programmable)
• Measuring range identification
• Measuring point identification
• External pressure sensor can be connected – for the correction of sample gas fluctuations
• Automatic range calibration can be parameterized
• Operation based on the NAMUR recommendation
The following table lists the zero offsets expressed in % H2 resulting from 10 % residual gas (interfering gas) in each case.
Component
Zero offset
Ar
-1.28 %
CH4
+1.59 %
C2H6 (non-linear response)
+0.04 %
C3H8
-0.80 %
CO
-0.11 %
CO2
-1.07 %
He
+6.51 %
H2O (non-linear response)
+1.58 %
NH3 (non-linear response)
+1.3 %
O2
+0.18 %
SF6
-2.47 %
SO2
-1.34 %
100 % air (dry)
+0.27 %
For residual gas concentrations differing from 10 %, the corresponding multiple of the associated value in the table provides
an acceptable approximation. This is valid for for residual gas
concentrations up to 25 % (dependent on type of gas).
The thermal conductivity of most gas mixtures has a non-linear
response. Even ambiguous results, such as e.g. with NH3/N2
mixtures, can occur within a specific concentration range.

General information
In addition to a zero offset, it should also be noted that the gradient of the characteristic is influenced by the residual gas. However, this effect is negligible for most gases.
In case of correction of the influence of interfering gases with additional analyzers (ULTRAMAT 6/ULTRAMAT 23), the resulting
measuring error can – depending on the application – amount
up to 5 % of the smallest measuring range of the respective application.

Pins 3-7 and 8-9 of the first and last connectors of a bus cable
must be bridged (see image).
Note
It is advisable to install a repeater on the device side in the case
of a cable length of more than 500 m or with high interferences.
Up to four components can be corrected via the ELAN bus, correction of cross-interference can be carried out for one or two
components via the analog input.

If the CALOMAT 6 is supplied with a specially cleaned gas path for high oxygen context ("Cleaned for O2 service"), please ensure
that you specify this when ordering spare parts. This is the only way to guarantee that the gas path will continue to comply with the
special requirements for this version.
