Chapter 2. Clamp-On Fixture and Transducer Installation
Figure 16: Moving the Downstream Transducer
2.1.2 Transducer Spacing = 320 to 940 mm, Traverses = 2, Fixtures = 2 (cont.)
IMPORTANT: Tight contact must be made between the bars on the two fixtures to ensure an accurate spacing.
5. See Figure 17 and Figure 18 below for examples of a completed installation in the following
situations:
Note: In this drawing,
LSL is the Lower Specified Limit and USL is the Upper Specified Limit for each fixture.
a. For a calculated transducer spacing of 320 to 620 mm for a 1 MHz or 0.5 MHz transducer, locate
the upstream transducer at the
USL1 position on the first fixture. Then, locate the downstream
transducer at the calculated transducer spacing position (
USL2) on the second fixture.
