Figure 85 Duct Mounting Installation Kit
The following numbers refer to Figure 85:
1 =
Duct wall
2 =
Flange
3 =
Sealing ring
4 =
Supporting bar (not included in the kit for HMT335)
5 =
Probe attaching part (to be fixed with the supporting bar)
6 =

NOTE
When the temperature difference between the duct and the air outside the duct is
remarkable, the supporting bar must be installed as deep in the duct as possible.
This prevents errors caused by the heat conduction in the bar and cable.
