1. Brief Module Description The Type 52-28 Weigh Module is especially designed for type SB8 and SB6 load cells. It is a weigh module with integrated check link and lift-off protection, which perfectly suits hopper and tank weighing applications. An adjustable overload protection and an integrated jacking device complete the technical features. Type 52-28 prevents unwanted forces from affecting the load cell performance and it eliminates oscillations caused by slow moving agitators.
3. Lift Off Protection and Jacking Device Fig. 2: Lift off protection and jacking device Max. lift off force: 5 kN (510 kg). The gap of is preset. The jacking device simplifies future maintenance. Max. jacking force: 5 kN (510 kg) Important: Both nuts of the jacking device are used as a transport lock. After the installation and prior to the commissioning these nuts have to be unlocked. 4. Overload Protection Fig.
. Dimensions and Check Link Orientation The movement of the load carrier is restricted by adjustable check links with rod ends. During the installation they have to be adjusted for minimum tension. This assures an optimal accuracy and the best repeatability. Each check link is designed for a max. force of 5 kN (510 kg). Fig. 4: Weigh module with check link Please take care for the correct module orientation when installing the weigh modules. Fig.
. Available Accessoires Fig. 6: Welding plate and welding fixture 7. Installation For tanks and hoppers it is usually impossible to position mounting holes in load carrier resp. in the foundation structure accurately enough to allow insertion of all mounting screws. The use of welding plates or bolting plates, the latter having pre drilled extra large mounting holes, are therefore convenient methods to solve this problem. Some of these alternatives are shown below.

Note that the welding plates are slightly bigger than the top resp. the bottom plates. This makes it easy to hold a piece of sheet metal against the welding plate to protect the weigh module from weld splashes.
