CAUTION
The influence of unsaturated hydrocarbons, alcohols or hydrogen in higher concentrations or over a longer period of
time (dose approx. 100,000 ppm x hours) will let the sensor drop out.
When used in transmitters with pump module, the O
2
LS sensor (68 09 630) must always be installed at vibration-free
locations. If used in this combination, vibrations may cause the measured value to deviate outside of the permissible
range.
