PROJECT PLANNING INFORMATION
SR-unit, probe
See 3.3.1 “Assembly prep-
aration at the measuring
point”, page 26
Select suitable flange
with tube
▸ Flange fitting is planned in steel ducts as standard;
corresponding flanges with tube are normally included in the
GM35 scope of delivery.
▸ Brick stacks or thick-walled ducts require a holding plate, to
be provided by the customer, and, if necessary, a longer
flange with tube, see Chapter 3.3.3 , page -27.
▸ If some of the components have not yet been delivered, you
may need to arrange an advance delivery of the flanges with
tube so that you can mount these as part of the preparations
for installation onsite.Alternatively, you can use a suitable
flange prepared onsite (or ANSI flange, check the Technical
Data, see page 128).
Duct openings
selection
▸ Determine the alignment of the measuring gap of the GM35
measuring probe in gas flow direction.
▸ Provide a suitably sized opening for the tube of the mounting
flange.
▸ Install the flange with tube tilted slightly downwards (> 1°) to
prevent condensate deposits and therefore corrosion.
▸ Provide for adequate clearance for installation and
maintenance activities for the duct insulation cutout.
▸ Plan sufficient clearance for pivoting the GM35 SR-unit,
removing the cable connector from the device, and pulling
the measuring probe out of the duct.
▸ Ensure the ambient temperature for the GM35 SR-unit is
between -20 and +55 °C (–40 °C during continuous
operation).
▸ For installation outdoors, plan a weatherproof cover.
Tools for start-up and
maintenance
▸ If adjustments are to be made at the measuring point
(prerequisites: clean, atmosphere free from sample gas;
protected from weather): order the angle flange for zero point
measurement (Part No. 2 017 833); when necessary, plan a
longer version of the flange with tube to ensure sufficient
distance from the duct.
Purge air unit
● Only relevant when
using a purge air unit,
i.e. not on systems
using a GPP probe
● See Section 3.3.1:
Assembly preparation
at the measuring point
Fitting location
selection
▸ Plan installation location on the duct in immediate vicinity
(5 m) of the GM35 SR-unit.
▸ Keep the purge air hose to the measuring probe as short as
possible (approx. 1.2 mbar pressure loss per meter).
▸ Ensure secure cable laying.
▸ Ensure dry and, whenever possible, dust-free intake air on
the purge air unit, use a preliminary filter when necessary.
▸ The intake air temperature should be between 0 and 55 °C.
For T < 0 °C, heat the purge air.
▸ Provide sufficient clearance for exchanging the filter element.
▸ Plan a weatherproof cover for installation outdoors as well as
sufficient clearance for fitting (and removing) the cover.
