Important Information 1. 1 Service life of the oxygen sensor The Analyzer module OXOR-E uses an electrochemical cell as oxygen sensor. The electrochemical cell has a limited service life and probably needs to be replaced several times during the overall operating time (detailed information → p. 24, §5.2). 1. 2 Application limitations Usage Unfavorable sample gas compositions, e.g. aerosols or high SO2 concentrations can shorten the service life of the electrochemical cell (→ p. 24, §5.2).

Product Description 2. 1 Product characteristics The Analyzer module OXOR-E is a measuring module for Series GMS800 gas analyzers. It is suitable to measure the oxygen concentration in standard applications. Analyzer module OXOR-P can meet higher requirements. 2.
Product Description 2.3 Measuring principle Fig. 2 Measuring principle 5 A/D BUS 4 6 3 O2 1 2 1 2 3 4 5 6 Sample gas Diffusion diaphragm Electrode Electrolyte Counter electrode Measurement amplifier The OXOR-E module is an electrochemical cell filled with an electrolyte. O2 can diffuse in the electrolyte through a PTFE diaphragm and is converted chemically on an electrode. The electrical charges formed in this manner create the current that can be used as measuring effect.

Functions in SOPAS ET 3.4.3 Damping Constant damping When "damping" has been programmed, the average value from the current measured value and the previous measured values (floating averaging) are displayed instead of the current measured value. Possible uses include: – Damping metrological measured value fluctuations (noise) – Smoothing fluctuating measured values when only the average value is relevant Damping is done in the Analyzer module and therefore affects all measured value displays and outputs.
Functions in SOPAS ET 3.4.4 Drift limit values Purpose Analyzer module drifts are caused, for example, by contamination, mechanical changes or aging effects. The total drift (i.e. the deviation from original state) increases gradually. It is not practical to keep compensating an ever increasing total drift through computation. Inspect and reset the Analyzer module when total drift has become very large. Drift limit values monitor total drift automatically. These also protect against erroneous adjustments.

Maintenance 5. 1 Information on shutting down The electrochemical cell is used up when in contact with air even when it is not in operation. ▸ When the gas analyzer is shutdown or stored (recommendation): Close off the sample gas path of the gas analyzer gas-tight to prevent contact with ambient air. 5. 2 Service life of the oxygen sensor Limited service life ● The electrochemical reaction slowly uses up the electrolyte in the oxygen sensor.
Maintenance Fig. 4 Oxygen sensor 5.4 Renewing the oxygen sensor 5.4.1 Built-in versions ● On standard built-in versions, the Analyzer module OXOR-E is fitted on a mounting bracket inside the device. The GMS800 enclosure has to be opened to renew the sensor. Only authorized skilled persons may carry out this work. ▸ Have the sensor on standard versions renewed by the manufacturer's Customer Service. ● In the S810 19" enclosure, the Analyzer module OXOR-E can be fitted behind the front panel.
Maintenance 5.4.2 Exchange procedure behind the front panel Information WARNING: Health hazards through dangerous gases If the sample gas could be a risk to health or dangerous: ▸ Thoroughly purge sample gas paths with a neutral gas (e.g. nitrogen) before opening components carrying sample gas. CAUTION: Hazards through incorrect assembly Oxygen sensor and base must be connected gas-tight. Ensure ▸ the sealing ring is intact ▸ sealing surfaces are smooth and free from dust.
