Electronic Unit E2000

General Information The electronic unit E2000 is a comfortable device for the using of ZIROX® oxygen probes. The signals of ZIROX® probes will be recorded with the E2000, processed to the oxygen concentration (normally in Vol.-%) according to the NERNST equation and given out by standard interfaces. The electronic unit E2000 supplies the probe with reference air via internal pump. Additionally the E2000 realises the power supply and the heating control for heated ZIROX® probes. Furthermore the probes will be monitored by the E2000 via cyclic measurements of the cell resistance. An error message will given out as necessary. The user can program two limit values (output via relay). In incomplete burned gases (reducing conditions) more values can be calculated (air factor , dew point, H2O/H2-Ratio, CO2/CO-Ratio, c(CO2) and c(H2O) in the water gas equilibrium. Precondition: known fuel gas composition, e.g. C/H-Ratio If requested the E2000 can be delivered with auto calibration function.

Flue gas probes

General Information Zirox flue gas probes are rugged sensors, which serve for λ-Determination in power and heat plants as well as for Measurement of oxygen partial pressure of furnace atmospheres. The probes are calibration, drift- and maintenance-free. At measurements in reducing atmospheres no falsification of gas composition occurs by measuring gas cooling in a suction line. The working temperature will be ensured by integrated heater. The using of high quality components and materials guarantees a high long term stability. Applications Flue gas measurements in power plants (TÜV-Approval according to "TA Luft, 13. und 17. BImSchV") Process gas measurements

High temperature probes

General Information The ZIROX® high temperature probe KS20 has been developed especially for using under extrem temperature conditions up to 1450 °C. With the KS20 the logging of the oxygen partial pressure direct in the burning chamber is possible. The KS20 is calibration, drift- and maintenance-free. At measurements in reducing atmospheres no falsification of gas composition occurs by measuring gas cooling in a suction line. The using of high quality components and materials guarantees a high long term stability. If the fuel gas composition is known it is possible to calculate the air factor λ, the CO-, CO2-, H2- and the H2O- concentration. This values can be given out by external electronic units (e.g. ZIROX® electronic unit E2000). The KS20 serves for process control and combustion optimisation (TÜV-Approval according to "TA Luft, 13. und 17. BImSchV") in power and heat plants as well as in incineration plants. It is also part of control for oxidising and reducing furnace gases in the ceramic industry. Applications Flue gas measurements in the high temperature range Furnace gas controlling in the ceramic industry Measurements in protective and inert gases

Miniature probes

General Information Potentiometric oxygen probes, which have been developed for the exhaust gas measurements in motor vehicles (λ-probes), will be frequently used in industrial equipments. According to the construction these probes have any disadvantages: because of the uncontrolled heating (steady working voltage) and ceramic cover films of the electrodes (which promote the diffusion of special gas components) important measuring errors can result. The SS27 with controlled heating and integrated primarily electronic has a great accuracy at comparatively lower costs. The main part is the approved ZIROX potentiometric zirconia based solid electrolyte cell (drift-, calibration- and maintenance-free). The using of high quality components and materials guarantees a high long term stability. Applications Oxygen measurements in protective gases Exhaust gas measurements in large-scale engines Control optimisation in firing equipments Furnace gas measurements in heat treatment equipments Optimisation of incineration plants monitoring of industrial processes under protective or inert gas atmospheres

O2-Measuring Device SGM7

General Information For an optimal quality and process protection the avoidance of oxygen, also as traces, is necessary in many technological applications. Not least by progressive introduction of quality assurance systems, e.g. according to ISO 9000, a constant monitoring and documentation of quality parameters becomes more important. The compact oxygen measuring device SGM7 is based on the approved, drift-, calibration- and maintenance-free ZIROX® zirconia technique. It contains the measuring cell as well the electronic for cell heating control, flow monitoring, integrated pump and signal processing. Via microprocessor the measuring cell signal will be processed according to the NERNST equation. The requested value will be given out by display and analog current signal.
