Figure 29 Probe Installation with Cable Gland (not available
from Vaisala)
The following numbers refer to Figure 29 above:
1 = Cable gland AGRO 1160.20.145 (T = -40 ... +100 °C)
2 = In pressurized conditions, use a locking ring (for example, 11x 1
DIN471)
The installation option in Figure 29 above is not available from Vaisala
and is presented here only as an example of how to achieve a vapor-tight
installation with HMT313/317 probes.
Ball Valve Installation kit for HMT318
The ball valve installation kit (Vaisala order code: BALLVALVE-1) is
preferred when connecting the probe to a pressurized process or pipeline.
Use the ball valve set or a 1/2" ball valve assembly with a ball hole of
ø14 mm or more. If you install the probe (ø12 mm) in a process pipe,
please note that the nominal size of the pipe must be at least 1 inch (2.54
cm). Use the manual press handle to press the probe into the pressurized
(< 10 bar) process or pipeline.
