EN-6 Sartorius
4 Installation
4.1 Before the Mounting
The foundation for the mounting kit must be horizontal (use spirit level), flat and rigid for the loads to
be supported.
The load must be distributed as symmetrical as possible in order not to partially overload the load cells.
The foundations of the mounting kits must be aligned and the supporting surfaces of the weighing
object (vessel or platform) must mount in parallel.
4.2 Mounting
• Mount lower and upper mounting plate at foundation or object support with bolts. It is
indispensable to ensure that the plates are located in parallel and vertically upon each other.
• Link upper and lower mounting plate with the flexible copper strap packed with the load cell; two
bolts with spring washer are included in the mounting kit.
Caution!
Do not damage the membrane on the bottom of the load cell!
• Clean the load cell seating in the mounting plate from dirt and insert the load cell only when all
welding work near the load cell and mounting work at the object is finished.
• Ensure that the load button is positioned correctly in the recess of the upper mounting plate. Check
the distance between load cell and protective ring. The distance must be the same around the load
cell.
• To prevent vertical force shunts, all mechanical connections (pipes, cables and bellows) of the object
to be weighed to its surrounding construction must be as flexible as possible. The overall load must
be supported by the load cells.
5 Check after Installation
After the installation of all mounting kits and load cells, the correct mounting must be checked. In
particular, force shunts must be avoided.
• Check, whether the constrainer is free of load, i.e. whether the constrainer it can be rotated around
its longitudinal axis.
If this is not the case, release the counter-nuts of the constrainer, and turn the hexagon, until the
constrainer is free of load. Subsequently, retighten the counter nuts and position the swivel bearing
eyes vertically.
After mounting also, check
• whether the load cell stands without tilt in the mounting kit,
• whether the upper mounting plate is positioned horizontally, and
• whether there are vertical space for movement and the required space for thermal expansion.
The space for movement required for displacement of the object to be weighed due to thermal
expansion, vibration, etc. can be used only if load cell and constraining unit are installed exactly.
