Figure 26 Installing the MMT338 Probe through a Ball Valve
Assembly
The following numbers refer to Figure 26:
1 = Manual press tool
2 = Handle of the ball valve
3 = Probe
4 = Process chamber or pipeline
5 = Groove on the probe indicates the upper adjustment limit
6 = Filter
7 = Ball of the ball valve
8 = Fitting screw
NOTE The probe can be installed in the process through the ball valve
assembly provided that the process pressure is less than 10 bars. This
way, the process does not have to be shut down when installing or
removing the probe. However, if the process is shut down before
removing the probe, the process pressure can be max. 20 bars.
NOTE When measuring temperature dependent quantities make sure that the
temperature at the measurement point is equal to that of the process,
otherwise the moisture reading may be incorrect.
