Weighing

Industrial Weighing Solutions: From Load Cell to Control System

An industrial weighing system requires appropriate load cells, mechanical mounting components, signal conditioning and integration with the machine or production process.

At Garma Electrónica, we supply SCAIME solutions for static and dynamic weighing, load measurement, batching and automation. Each application must be evaluated according to its capacity, required accuracy, mechanical loads and operating conditions.

Types of Load Cells

Compression Load Cells

Designed to measure compressive forces. Applications include tank, silo and platform weighing, using suitable mounting components to ensure correct load transmission.

Tension and Compression Load Cells

Measure tensile forces, compressive forces or both, depending on the model. They can be used in suspended weighing systems, industrial machinery and force measurement applications.

Bending Beam and Shear Beam Load Cells

Used in platforms, tanks and other weighing installations where the mechanical arrangement and load distribution are compatible with these designs. Rated capacity, dimensions and mounting requirements must be checked.

Single-Point and Digital Load Cells

Single-point load cells are suitable for selected weighing platforms and scales. Digital versions may incorporate signal processing and application-specific functions for batching or dynamic checkweighing, depending on the model.

Load Pins

Load pins measure forces in mechanical assemblies using pins or shafts. Selection requires information about loading conditions, installation geometry, force direction and applicable safety requirements.

Weighing Electronics and PLC Integration

Conventional load cells typically produce low-level electrical signals requiring signal conditioning. Weighing transmitters and controllers process these signals and communicate measurement data to automation systems.

The SCAIME eNod range includes devices designed for different weighing and batching functions. Dedicated PLC modules are also available for selected control platforms, including the PMESWT weighing module for Schneider Electric M580.

Batching, digital filtering, dynamic weighing functions and industrial communication protocols depend on the controller and its configuration. These capabilities must be verified for the exact product reference.

How to Select an Industrial Weighing System

The rated capacity of an individual load cell does not directly determine the usable capacity of the complete weighing system. Load distribution, mechanical installation and the required safety margins must also be considered.

Industrial Weighing Applications

• Tank and silo weighing: measuring stored quantities using load cells.
• Batching and mixing: controlling quantities during filling and batch preparation.
• Dynamic checkweighing: production-line weight checking and sorting with equipment suited to the required throughput.
• Industrial machinery: integrating weight and force measurement into automated equipment.
• Logistics and material handling: load monitoring in handling equipment and processes.

Why Mechanical Mounting Matters

Even a correctly selected load cell may produce unreliable measurements if the installation introduces unintended forces. Mounting kits, supports, articulated connections and accessories help address alignment, thermal expansion and force transmission within the manufacturer's specified operating conditions.

For tanks and silos, rigid pipework, side loads and structural movement should be evaluated before finalising the weighing arrangement.
