4.2 Mounting by straps to blind plates
The blind plates are 15mm stainless steel,
and are equipped with a special gasket to
properly affix the blind plate to the flange on
the instrument.
The blind plates may be welded or machined
in any way to properly affix and support the
instrument in the desired position.
Do not distort or weaken the blind plates, as
they support the full weight of the Analyzer
PRO. Weight is 33 pounds, or 15 Kg.
The mounting flange of the instrument is shown at
the top.
The “blind plate” and gasket are shown at right.
The clamp is a “Tri-Clover” style. It is an ISO Clamp,
76.1mm. This style of clamp is used in sanitary
installations, and is known for ruggedness as well as
ease of installation and removal.
Do not attempt to drill mounting holes through the
cabinet or cover, as this will compromise the
protective sealing of the instrument enclosure. Any
holes drilled in the cabinet will invalidate the
instrument warranty.
Before mounting, determine the optimal desired position of the sampling window, and arrange for
the blind plate positions to correspond to that desired sampling position. (With a fiber optic probe
this position may be less critical.)
Before mounting the instrument, verify that the blind plates are in the correct locations, and that the
fabricated mounting arrangement will support the full weight of the instrument. When mounted, the
distance from the outside flat of the top blind plate, to the outside flat of the bottom blind plate is
19.25” (384mm). Leave some provision for movement of the mounting brackets (such as slotted
holes) to ease mounting and final positioning. At least ¼” (6mm) of movement is recommended. The
gaskets have a molded ridge on each surface, and the mounting must accommodate this ridge
during assembly.
The blind plate, gasket, and mounting flange should be securely clamped in place, top and bottom.
There should be no play in the clamp or mounting mechanism. This method of mounting provides for
easy mounting and dismounting, if required. The cover, secured by 32 bolts and sealed by a
compressive gasket, has two handles which allow lifting. Please wear protective gloves when lifting.
