Accessories for Siemens Load Cells – Mounting, Protection and Signal Technology

Accessories for Siemens load cells include mounting kits, load feet, base plates, protective enclosures, cable solutions and connection components for integration into industrial weighing systems. Their purpose is secure and reproducible installation, environmental protection, correct force introduction and reliable signal transmission under harsh industrial conditions.

FAQ on Accessories for Siemens Load Cells

What types of mounting kits are available and what is their purpose?

Mounting kits typically contain load feet, base plates or pendulum/sliding bearings and ensure that the load cell is properly fixed in the frame. This ensures defined force introduction, prevents side loads and torsion, and accounts for thermal expansion of the structure.

When should spring-loaded or pendulum-mounted bearings be used?

Spring-loaded or pendulum-mounted bearings are particularly useful when the supporting structure expands or deforms due to temperature changes or mechanical loads. They prevent stress in the load cell body caused by thermal or mechanical distortions and ensure uniform force introduction.

How to choose appropriate load feet for my load cells?

The load feet must match the geometry of the load cell, the load direction and the installation environment. For platform or hopper scales, flat, stable load feet are often used; in belt or roller-conveyor systems, articulated or joint-mounted constructions may be advantageous to allow movement and minimize side loads.

What is the role of base plates and guiding elements?

Base plates and guiding elements ensure that the force is applied exactly in the intended direction and that the load cell is not subjected to lateral forces or torsion. They are important to avoid measurement errors and to prolong the service life of the load cell.

Why is correct cable and connection equipment important?

Shielded cables, shielded connectors and proper grounding are essential to prevent signal interference, noise or EMC problems — especially with long cable runs or in electromagnetically “noisy” industrial environments. Additionally, correct earthing and potential equalization are critical for stable weighing results.

Are there protection solutions against dust and moisture?

Yes — protective enclosures, cable glands with seals, protective coatings or hermetic sealing secure the load cell and electrical connections against dust, moisture or chemical exposure. This is important in hygienic, dusty or routinely cleaned environments.

How does the accessory choice affect measurement accuracy and repeatability?

A mechanically stable, correctly aligned mounting with optimal load feet and guiding elements ensures the force is always applied in the same way. This improves linearity, minimizes corner load errors and enhances long-term stability — crucial for precise and reproducible weighing processes.

When are pendulum bearings or articulated mounting kits necessary?

If the supporting structure is subject to vibrations, thermal expansion or mechanical movements — for instance in conveyor systems — pendulum bearings or articulated mounting kits ensure inevitable movements do not introduce side loads on the load cell and the measurement remains stable.

What should be considered regarding EMC and grounding during installation?

Cable shielding should be properly terminated at both ends, equipotential bonding between the load-cell frame and the weighing unit is required, and signal and power cables should be routed separately. The weighing electronics should include suitable filters or surge protection to avoid signal distortions.

How should accessories be dimensioned for different weighing setups?

Selection of mounting kits, load feet, guiding elements and cables depends on the type of scale (hopper, platform, conveyor), structure height and rigidity, environmental conditions (dust, moisture, temperature fluctuations) and required precision. Components must be sized according to load capacity, mechanical stress and environmental requirements.
