When the probe is installed directly on the process wall or pipe, note that

a closing valve may be needed on both sides of the installed probe so that

the probe can be removed from the process for calibration or

maintenance.

If the probe is installed in a pressurized chamber, always make sure that

the pressure of the chamber is equalized with the ambient pressure prior

to removing the probe. When the probe is pulled out for maintenance,

cap the hole with a capped nut. This way, the process can be running

although the probe is not in place. For ISO threaded connections, a plug

(Vaisala order code 218773) is available.
