Mounting Information
Analyzer PRO is provided with an innovative, rugged integral flange-mounting system that permits
easy installation and service. There are two mounting flanges, top and bottom, to which are
mounted “blind plates” using a rugged, industry-standard tri-clamping mechanism. This approach
eliminates bolt holes or other entry points for contaminants.
The mounting flanges are sized to attach directly to 3” (76.2 mm) diameter stainless steel piping,
which is widely used in sanitary installation areas. To mount using pipe, determine where the window
or fiber will be positioned, and install pipes in the corresponding positions for supporting and
mounting the enclosure. The pipes should have the proper flange ends to accept the clamps to lock
the Analyzer PRO instrument in place.
Two alternative methods are shown. This first is preferred in most cases.
4.1 4.1 Mounting Frame, U-Bolts Secured to Mounting Flanges
Many installations will be performed using a fabricated mounting frame which can be bolted to a
solid surface in the plant. This mounting method should be well-planned, so the sample window (or
fiber optic probe) is in the right location upon final installation. In this case a Analyzer PRO Fiber Optic
Probe system is being installed.
This sequence shows mounting the frame to the Analyzer PRO instrument first, then bolting the
frame (with Analyzer PRO installed) to the mounting bolts.
We advise using a cart or frame to support the instrument during mounting, to avoid damage. Use
lab jacks as shown, to make height adjustment easy. Protect the fiber optic cable, as well as the
power and communications cables. Do not kink, bend, or otherwise stress the fiber optic cable in any
way, as this may damage the internal fibers and cause loss of energy.
Safety NOTE: Please follow all site safety rules regarding lifting and physical exertion while mounting
the Analyzer PRO.
In addition, use of a rolling cart provides an easy way to protect the fiber optic cable, power cable,
and communications cable – they are carefully coiled on the lower shelf of the cart, to avoid damage.
1. Remove the locking clamps and blind
mounting plate from each mounting
flange. Remove the gasket as well.
Keep all these parts in a safe place, in
case they are needed at some point in
the future.
