Note the following if using a strip source.
1. Refer to the source housing drawings to determine the position of the
active length of the strip source and other mounting dimensions.
2. Secure the housing with the 1/2-inch (12 mm) bolts and lock washers
(six places). The housing mounting face allows clearance for bolts or
studs extending up to 2-1/4 inches (57 mm) from the mounting
surface.
3. For best results, the measurable range should be less than the active
length of the strip source(s). Position the strip source so that the
bottom of the active length of the source is even with the minimum
level to be measured. If the measurable range must be greater than the
active length of the strip source, position the top of the active length of
the source so that it is even with the maximum level to be measured.
4. The mounting surface should be vertical. The mounting should ensure
accurate beam alignment with the detector and provide for easy left-
right angular adjustment.
5. Install the source housing with its mounting face as close to the vessel
as practical, with no structural material (mounting tabs, brackets, etc.)
between the beam area and the vessel.
If your source housing includes a pneumatic shutter actuator, refer to
drawing 866664 for installation details.
