Risk of crushing!
The cylinder rotates automatically! Fingers may get jammed on the
strap or on the locking piece.
Never change the factory-adjusted setting for attenuation of the
pneumatic actuator. This setting ensures that the cylinder rotates
slowly and the risk of getting your fingers crushed is low.
2.5.3 Point Source 45° Cascaded
For large measurement ranges or vessels with small internal diam-
eter, it may be necessary or beneficial to use two point source
inside the measurement range to minimize the total activity and to
improve the linearization options. Figure 2-27 shows the appropri-
ate measuring geometry. The shieldings are installed below each
other in a distance of size H. For detailed information on the size H
please see the respective documentation. Depending on the size of
the measuring range, this arrangement can be realized with one or
several detectors.
