If you wish to remove the probe from the process, note that you have to
pull the probe out far enough. You cannot close the valve if the groove
on the probe body is not visible.
Sampling Cell for MMT318
It may be necessary to use a sampling cell if the MMT318 probe cannot
be installed directly into the process pipe, for example, if the pipe is too
small for the probe. Using a bypass sampling line may be feasible in
these cases. Sampling Cell with Swagelok Connectors (Vaisala order
code: DMT242SC2) is available as an optional accessory.

Mounting the MMT317
The MMT317 uses a small pressure-tight probe and is ideal for tight
spaces with threaded connection. The small probe is installed using the
threaded fitting bodies as instructed in this section.
NOTE Do not unsolder and then again resolder the sensor head cable from and
to the printed board during installation; this procedure may alter the
calibration of the transmitter.
