Introduction
Load cells are the core components of all industrial weighing and force measurement systems. Whether you are building automated batching systems, conveyor belt scales, material testing machines, or industrial tank weighing equipment, choosing the right load cell directly affects system accuracy, stability, and service life. Many automation equipment manufacturers face unstable data, inaccurate weighing, or short sensor service life due to improper load cell selection.
In this guide, DAYSENSOR explains the key factors for selecting industrial load cells to help you find the most suitable sensor for your automation project.
1. Determine the Correct Measuring Range (Capacity)
The measuring range is the most basic selection parameter. Industrial load cells must reserve a certain safety load to avoid sensor damage caused by instantaneous impact pressure.
Selection rule: Actual working load × 1.2~1.5 = suitable load cell capacity
For dynamic automation equipment such as conveyor belts and reciprocating testing machines, it is recommended to choose a larger safety margin to prevent fatigue damage from frequent pressure changes.
2. Choose the Right Accuracy Class (C3 / C6)
Industrial load cells are mainly divided into C3 accuracy and C6 accuracy grades:
-
C3 Load Cell: Suitable for general industrial batching, material weighing, and factory automation. High cost performance, stable data, and widely used.
-
C6 Load Cell: High-precision model, suitable for laboratory testing, precision testing equipment, and high-standard automated production lines.
All DAYSENSOR shear beam load cells, S-type load cells, and spoke load cells support C3/C6 optional accuracy to meet different industrial automation standards.
3. Select Load Cell Type According to Application Scenarios
-
Shear Beam Load Cell: Suitable for platform scales, tank weighing, conveyor weighing, and industrial batching systems.
-
S-type Load Cell: Suitable for tension and compression testing, material force measurement, and mechanical testing equipment.
-
Spoke Type Load Cell: Suitable for large-tonnage pressure testing, machinery manufacturing, and heavy industrial equipment.
-
Torque Sensor: Used for motor testing, dynamic torque detection, and automated power testing benches.
4. Consider Environmental Protection Level (IP67)
Factory automation equipment usually faces dust, moisture, and oil pollution. Industrial load cells must have good waterproof and dustproof performance.
DAYSENSOR industrial load cells adopt IP67 waterproof protection and all stainless steel structure, which can work stably in harsh factory environments for a long time.
5. Confirm Signal Output Method
According to your PLC system, display instrument, and data acquisition module, select the corresponding output signal:
-
Millivolt voltage signal (original sensor signal)
-
4-20mA standard analog signal
-
RS485 digital communication signal
DAYSENSOR supports customized output signals and matching load cell transmitters and display controllers.
Conclusion
The correct selection of load cells can greatly improve the stability and measurement accuracy of industrial automation equipment.
