7.3.2. The pressure evacuation holes
feature
The direct welding holder is equipped with a safety mechanism, to
prevent danger to service personnel.
If the probe is unscrewed while there is still pressure in the process,
the o-ring between the probe and the steel frame of the holder loses
its seal. In this case, process medium enters the holder and exits
through the pressure evacuation holes before the probe is loosened
entirely (thereby informing the personnel that there is still pressure in
the process).
In this case, tighten again the probe until the process is no longer
under pressure. The probe can be then safely removed.
