        Analytical-/ Operational Data

        Measuring principle

        Difference in thermal conductivity (?λ) of various gases

        Measured quantity

        Concentration of a particular gas component in binary and quasi-binary mixtures.

        In many applications involving multi-component gases the inherent non-selectivity of the thermal conductivity principle can be minimized using interference correction techniques.

        Physical interference reduction is sometimes possible with certain applications due to the wide temperature range of the CONTHOS' TC-detector.

        Measuring ranges

        Up to 3 independently configurable, switchable ranges. The reference response of each range is factory linearized (4th-degree polynomial).

        Suppressed output ranges within the corresponding reference range can be easily configured.

        Range switching is accomplished manually, automatically and/or externally (via optional digital inputs).

        lowest range: 0 - 0.5% H2 in N2   or   99.5-100% H2 in N2    (or equivalent ?λ) largest range: 0 - 100% H2

        Response time τ90

        approx. 2 sec. (dependent upon gas flow and analyzer configuration) (integration time configurable)

        Precision

        ≤ 0.5% F.S.O. (typically better than ± 0.2%  F.S.O.)

        Accuracy

        better than ± 0.5%  F.S.O. (typically better than ± 0.3%  F.S.O.)

        Calibration

        Manual: 2-point (offset/span) calibration  Option: automatic or semi-automatic calibration in conjunction with the optional digital I/O-board or RS-485

        Interference correction

        3 correction channels for static and/or dynamic interference correction (dynamic correc tion only in conjunction with the optional analog inputs or RS-485)

        One of the prerequisites for dynamic interference correction is the availability of a selective signal, proportional to the particular gas component to be corrected for. The processing of analyzer ranges with a suppressed zero range is not possible.
