Quality and Safety Considerations of Mini Load Cell

Some important quality and safety considerations ensure the reliability and stability of the load cells in performance while maintaining adherence to safety protocols across industries.

Precautions for Quality

To ensure the measurement accuracy and reliability of the mini load cells, follow certain precautions. Pay close attention to factors like environmental conditions and use original components as substitutes during maintenance. Proper calibration is a must, while any system that uses the load cell should stay protected from external factors like electrical interference, which may impact performance.

Use of Quality Materials

Quality materials and standards to manufacture mini load cells ensure long-term use. But load cells have to meet specifications set by the International Electro-Technical Commission (IEC/EC 60239) and ISO 376, which describes materials, dimensions, and construction details. Stainless steel, aluminum alloys, and sometimes, hardened steel are the materials for making load cells. These provide mechanical strength and satisfactory working in hazardous environments. So, keep checking that the load cell is made from quality materials.

Sealing and Protection

In harsh environments, sealing the load cells ensures protection from moisture, dust, and chemicals. Choosing cells with ingress protection (IP) ratings means extra safety in these conditions. Concern industries opt for cells rated IP65 or higher to get reliable performance without compromising safety.

Use of Original Components

Replacing load cell components, like connectors or mounting hardware, warrants original equipment manufacturer (OEM) parts. Using non-OEM components can introduce variability in system performance and increase failure probability. Besides, they never give the desired outcome like OEM parts.

Overloading and Underloading

Overloading can damage the load cell and decrease accuracy. To prevent this, users need to install overload protection devices such as mechanical stops. Similarly, underloading cell causes inaccurate readings. So, don't allow any load cells to operate continuously below their minimum capacity.
