FAQ

What is a load cell and why is it used in agriculture?

A load cell is a sensor that measures weight by converting a mechanical force into an electrical signal. In agriculture and livestock farming, load cells are essential for accurately weighing feed, grains, silage, fertilizers, and other materials, helping farmers and machine operators improve efficiency and reduce waste.

How does a load cell work?

A load cell works through the controlled deformation of a metal body equipped with strain gauges. When a load is applied, the strain gauges change their electrical resistance. This variation is converted into a low-level electrical signal proportional to the applied weight and processed by a weighing indicator or control unit.

What types of load cells are used in agricultural machines?

Agricultural applications typically use:
  • Compression load cells for high-capacity and heavy-duty machines
  • Bending beam load cells for feed mixers and trailers
  • Spindle (pin) load cells integrated into structural parts
The choice depends on machine design, capacity, and installation requirements.

Which load cells are suitable for feed mixers?

Feed mixers require load cells that combine high accuracy with mechanical robustness. They must withstand vibrations, shocks, and harsh environments while ensuring stable and repeatable weight measurements, which are critical for precise ration preparation.

What affects the accuracy of a load cell system?

Load cell accuracy depends on several factors:
  • Mechanical design and material quality
  • Strain gauge configuration
  • Temperature compensation
  • Correct mechanical installation
  • Cable shielding and signal integrity
The machine structure and load distribution also play a key role.

How do temperature changes affect load cell measurements?

Temperature variations can influence both the mechanical and electrical behavior of a load cell. High-quality agricultural load cells include temperature compensation to ensure reliable measurements across a wide operating range typical of outdoor and farm environments.

What does IP67 or IP68 protection mean for load cells?

The IP rating defines resistance to dust and liquids:
  • IP67: fully dustproof and protected against temporary immersion
  • IP68: suitable for continuous immersion
For agricultural use, high IP protection is essential to resist moisture, slurry, fertilizers, and frequent washing.

Why is correct mechanical installation so important?

Incorrect installation can introduce lateral forces, torsion, or uneven load distribution, leading to measurement errors and premature wear. Proper mounting ensures accurate readings, long service life, and consistent system performance.

Can multiple load cells be connected in one weighing system?

Yes. Agricultural machines often use multiple load cells connected through a junction box. This allows signal balancing between weighing points and ensures accurate total weight measurement across the entire machine.

What is NIR technology and how does it work?

NIR (Near Infrared Reflectance) technology analyzes materials by measuring how they reflect near-infrared light. When infrared light hits a product, part of it is absorbed and part is reflected. The reflected spectrum is processed through calibration models to determine the chemical composition of the material in real time.

What parameters can be measured with a NIR sensor in agriculture?

NIR sensors can measure key nutritional and compositional parameters such as:
  • Dry Matter (DM)
  • Moisture
  • Protein
  • Fiber (NDF, ADF)
  • Starch
  • Ash
  • Ph
  • N
  • P
  • K
  • etc
These values are essential for feed quality control, ration accuracy, and process optimization.

Why install a NIR sensor directly on agricultural machines?

Installing a NIR sensor directly on the machine allows real-time analysis, eliminating delays and sampling errors typical of laboratory testing. Operators can immediately react to variations in raw materials, improving accuracy, efficiency, and consistency during daily operations.

What are the main benefits of on-machine NIR analysis?

On-machine NIR technology provides:
  • Immediate decision-making based on real data
  • Reduced feed variability and waste
  • Improved process control
  • Higher nutritional consistency
  • Better economic performance
It transforms agricultural machines into smart, data-driven equipment.

How is NIR used on forage harvesters and combines?

On forage harvesters and combines, NIR sensors continuously analyze the harvested material during operation. This allows monitoring crop quality, dry matter, and nutrient variability directly in the field, supporting yield mapping, logistics planning, and more accurate feed management downstream.

What is the role of NIR technology on slurry tankers?

When installed on slurry tankers, NIR sensors measure nutrient content (dry matter, N, P, K) in real time during spreading. This enables more precise nutrient application, better compliance with environmental regulations, and optimized fertilization strategies based on actual slurry composition.

How is NIR applied on feed mixers (self-propelled and trailed)?

EVONIR analyzer can be installed both on self-propelled and trailed feed mixer.
  • Self-propelled:  The NIR sensor is installed on the feed mixer cutter and performs real-time analysis of the material, automatically adjusting the loading quantity of each ingredient based on the measured values.
  • Trailed: The sensor is installed on the feed mixer tub and allows the analysis of TMR quality and mixing homogeneity. This provides clear indications of the overall quality of the mixed ration.
All collected data are transmitted to the DTM feeding management software for further analysis and monitoring.

Why is NIR on feed mixers a key technology for precision feeding?

NIR sensors on feed mixers enable:
  • Immediate correction of ingredient variability
  • Consistent ration quality day after day
  • Reduced feed costs
  • Improved animal performance
This makes NIR a core technology for true precision feeding strategies.

The measured parameters are integrated into the plant control system (PLC, SCADA, or central control unit) and can be used to enable closed-loop control strategies. Based on the NIR analysis, automatic feedback actions can be implemented to:
  • Adjust drying temperature and residence time
  • Optimize milling or extraction processes
  • Control blending, dosing, or separation phases
  • Improve product consistency, efficiency, and energy consumption
This approach transforms NIR from a monitoring tool into an active component of process optimization and industrial automation.
