NOTE: Dimensions shown in in. (mm).

In some duct-mount application, it is desirable to use a 

compression fitting to reduce air leakage at the sensing 

element location. For these applications, first mount a waste 

nut on the duct to ensure secure mounting. See Fig. 12. See 

Table 6 for part numbers.

NOTE: Do not use this mounting method for liquid 

applications.

The averaging element must be supported so it is distributed 

evenly across the entire height and width of the duct. It can be 

fastened to perforated strap iron (see Fig. 13) or mounted with 

314439 Mounting Clips (see Fig. 14). This type of mounting 

requires threading the element through a grommet inserted in 

a hole in the duct wall.

For ducts with limited access, the 7640HX Averaging Element 

Mounting Kit allows mounting the element through a single 

hole in the side of the duct. This kit requires a length of 1/2 in. 

EMT conduit. See Fig. 15.
