Measuring system XS22-E2010 9 Use of ZrO -probes 9 Details for the use of ZrO -probes in vacuum technology 9.1 Theoretical relations Potentiometric ZrO -probes measure the difference of the oxygen partial pressure at both electrodes. One electrode is fixed inside, the other one outside the ZrO -tube.
Measuring system XS22-E2010 9 Use of ZrO -probes The following applies: 2064 ⋅ ϕ ⋅ − ⋅ 9.2 Instructions for calibration When operating in vacuum differences in the electrodes’ temperatures usually cause indeterminable thermoelectric voltage which depends on the respective production unit.

Measuring system XS22-E2010 9 Use of ZrO -probes In practice, if the probe is needed for the adjustment and replication of defined conditions only, it is sufficient to determine the probe signals empirically in a successful trial. The operating mode has to be set up so as to receive the requested probe signal.
In case of defects and faults within 12 months (probe) and 24 months (electronics assembly) respectively after dispatch, ZIROX will clear faults at its own option by repair or replacement. The purchaser must give prompt written notice to ZIROX.
