Compression Load Cell, 300kg/500kg/2 ton/10 ton to 30 ton
After purchasing one RJ load cell, you can buy a special digital panel meter to obtain readings directly, or buy a transmitter to output standard signal to PLC, DCS and other systems. Customized output signal is 0-5V, 0-10V, or 4-20mA.
Note: The load cell cannot be connected to both the transmitter and the controller at the same time — only one can be selected.
Compression load cells have capacity range from 300kg, 500kg, 1000kg, 10 ton to 30 ton. Load cell capacity can be customized according to customer requirements.
The compression button load cell is a high-precision measuring device mainly used to measure small weight or pressure changes. The low profile and compact design make it ideal for use in tight spaces, and the all-stainless steel construction provides corrosion resistance and reliability in harsh industrial environments. Unique button design ensures accurate load distribution.

Tips: What factors can affect the performance of a Compression Load Cell?
Several factors can impact the performance of a Compression Load Cell:
- Temperature Variations: Extreme temperature fluctuations can cause measurement inaccuracies due to changes in the load cell’s material properties. Many compression load cells are designed with temperature compensation to mitigate this issue, but temperatures outside the specified operating range may still affect accuracy.
- Improper Alignment: If the load cell is not correctly aligned with the applied load (i.e., if it experiences side loading or bending), it can lead to inaccurate readings or even damage to the cell.
- Overloading: Exceeding the rated capacity of the load cell can cause permanent damage and affect the accuracy of measurements. Regular calibration and careful attention to the maximum rated load are necessary to avoid overloading.
- Vibration and Shock: Mechanical shock or vibrations from surrounding machinery can impact the accuracy of measurements. It's important to install the load cell in an environment where vibrations and shock are minimized, or use damping materials to absorb impacts.
- Electrical Interference: External electrical sources, such as motors or other machinery, can generate electromagnetic interference (EMI) that affects the signal output. Using proper shielding and grounding techniques can minimize this issue.
