Maximum wall thickness: 4 mm (0.16 in)
2 Screws for tightening the flange in place (4 pcs, Ø 5 mm (0.19 in))
3 Nut for mounting the temperature probe gland (HPP272 only)
4 Temperature probe gland diameter: 8 mm (0.31 in) (HPP272 only)
Seal the lead-throughs on the metal body of the probes.
HPP272 only: Install the main probe body and the temperature probe 60 … 100 mm (2.36 … 3.93 in)
apart from each other. The temperature probe must be far enough to prevent heat from the main probe
body from aecting the temperature measurement, but close enough so that the two probes measure
the same environment. When installing the probes horizontally, place the temperature probe
downstream of the warmed main probe body.
