Description 3.4 Functional principles In contrast to other gases, oxygen is highly paramagnetic. This physical property is used to determine oxygen concentration in gases. Oxygen molecules in an inhomogeneous magnetic field always move toward the higher field strength. This results in a higher oxygen concentration where the field strength is higher (higher oxygen partial pressure).
Description 3.5 Reference gas monitoring, OXYMAT 7 Reference gas monitoring, OXYMAT 7 NOTICE Reference gas monitoring Monitor the reference gas pressure using an internal (optional) or external pressure switch. Interrupt the sample gas supply if the reference gas pressure is too low, and flush the sample gas path with inert gas.
Application planning Application planning General In order to achieve a good measuring quality, the installation location should be free of vibrations. Building vibrations, in particular in the frequency range from 8 to 12 Hz, can influence the measured signal. Check using the technical specifications that your device is suitable for the measuring task. WARNING Feeding of gases with flammable components A device in the standard version must not be operated in hazardous areas.
Application planning 4.2 Operation with at least one OXYMAT 7 Operation with at least one OXYMAT 7 Overview If the sample gas is pumped into the analyzer module, surges may occur through operation which can result in an unstable display of measured values. Fitting a sample gas restrictor in the sample gas inlet of an OXYMAT 7 remedies this situation.

Commissioning 9.2 OXYMAT 7 OXYMAT 7 9.2.1 Selection of the reference gas The various measuring spans must have at least one common value. This value is then defined as the "physical zero point" and applies to all the measuring ranges. The reference gas can be selected on the basis of the "physical zero point".
The result of this deviation has to be fed into the analyzer module OXYMAT 7 as an interfering gas concentration. For further information on this, refer to the SIPROCESS GA700 operating manual. Accompanying gas (concentration 100 vol. %) Zero point deviation in vol.

Commissioning 9.2 OXYMAT 7 9.2.4 Introducing reference gas Always introduce the reference gas before beginning the measurements. In the case of temporary interruption of the measurements, reference gas should also always flow. This prevents the sample gas remaining in the measuring chamber from diffusing to the microflow sensors and possibly destroying them.
Commissioning 9.2 OXYMAT 7 9.2.8 Checking the sample gas path for leaks The leak test is carried out with air or nitrogen at the operating temperature. The leak rate is determined in accordance with the pressure drop method. The pressure of the gases (air or nitrogen) enclosed in the gas line is monitored within a defined period.

ESD guidelines ESD Guidelines Definition of ESD All electronic modules are equipped with large-scale integrated ICs or components. Due to their design, these electronic elements are highly sensitive to overvoltage, and thus to any electrostatic discharge. The electrostatic sensitive components/modules are commonly referred to as ESD devices. This is also the international abbreviation for such devices.
ESD guidelines B.1 ESD Guidelines Electrostatic charging Anyone who is not connected to the electrical potential of their surroundings can be electrostatically charged. The figure below shows the maximum electrostatic voltage which may build up on a person coming into contact with the materials indicated. These values correspond to IEC 801-2 specifications.
