Page 12: Description
Shear beam load cell K30S / K30N Description General The shear beam load cell K30S / K30N is used as a sensor in industrial scales (e.g. platform scales, floor scales, silo scales) to determine the weight of placed products. The shear beam load cell K30S is made of alloyed steel, nickel-plated. -
Page 13: Functionality
Shear beam load cell K30S / K30N Description | 2 Functionality The shear beam load cells K30S / K30N are designed for installation in industrial scales and are used for the precise weighing of the product loaded onto the scale. -
Page 14: Installation & Connection
Shear beam load cell K30S / K30N Installation, connection Control When the shear beam load cell K30S / K30N is delivered, check the packaging, the load cell and possible accessories for visible damage. Packaging and disposal Keep all parts of the original packaging for a possible return. -
Page 15: Connection
90° Attention Ensure that the shear beam load cell K30S / K30N is used exclusively in the prescribed load direction (see arrow on the load application face of the load cell). Otherwise, measurement results may be distorted, and the load cell's lifespan may be affected. - Page 16 3 | Installation, connection Shear beam load cell K30S / K30N Note For the operating instructions of the evaluation electronics, please refer to the separate documentation of the evaluation electronics. The following points must be observed during installation: • The support surfaces of the load cells must be coplanar (aligned in one plane) and sufficiently rigid.
-
Page 17: Connection
Shear beam load cell K30S / K30N Installation, connection | 3 • Never overload the load cell, even temporarily, as this can lead to permanent damage. • If necessary, seal the cable entry points of the junction box with a suitable sealing compound to prevent moisture ingress. -
Page 18: Electrical Connections
3 | Installation, connection Shear beam load cell K30S / K30N 3.4.3 Electrical connections The connection cable to the evaluation electronics is four-core, shielded as standard. An optional six-core connection cable is available. The cable cross-section should be selected according to the required cable length (between the junction box and the evaluation electronics). -
Page 19: Parallel Connection Of Multiple Load Cells
Shear beam load cell K30S / K30N Installation, connection | 3 3.4.4 Parallel connection of multiple load cells To connect multiple cells in parallel, a sealed junction box with a terminal board must be used if necessary. The extension connection cables of the load cells must be shielded, placed individually in cable ducts or pipes, and routed as far away as possible from the power cables. -

Page 21: Measures Against Lateral Displacement
Shear beam load cell K30S / K30N Installation, connection | 3 3.4.7 Measures against lateral displacement Attention Necessary measures must be taken to prevent lateral displacement and tipping, depending on impacts and vibrations, wind load, seismic classification, and ground conditions. -
Page 22: Operation
For the operation description of the evaluation electronics, the separate documentation of the evaluation electronics must be observed. Warm-up time The minimum warm-up time for the shear beam load cell K30S / K30N before starting the measurement (calibration) is approximately 20 minutes. Checking the load cells with a multimeter Note Using a load cell tester (available from Bosche Wägetechnik), check whether... -
Page 23: Test Of Load Cell Input (Quick Access) Via Resistance Measurement
Shear beam load cell K30S / K30N Operation | 4 4.3.1 Test of load cell input (Quick access) via resistance measurement • Turn off the load cell tester. • Disconnect the cells from the instrument and check whether the junction box shows any signs of moisture, which may indicate condensation or water ingress. -
Page 24: Dimensioning The Load Cell Nominal Load
4 | Operation Shear beam load cell K30S / K30N Dimensioning the load cell nominal load For safety reasons, it is recommended to use load cells at a maximum of 70- 80% of their rated capacity for dead load (static), assuming that the load is evenly distributed across the entire weighing system. -
