Truck Scale Load Cells
Truck scale load cells are the critical sensing components used in weighbridges and vehicle scales to accurately measure heavy truck and axle loads. These load cells are engineered for demanding industrial environments where extreme weight, constant traffic, vibration, and outdoor exposure are common.
Most truck scale systems use multiple high-capacity load cells working together beneath the scale deck to distribute and measure weight evenly. Truck scale load cells are typically constructed from stainless steel or alloy steel and are designed to deliver long-term accuracy and durability in harsh conditions.
American Scale Supply offers a wide selection of truck scale load cells for new installations, system upgrades, and replacement applications. Our truck scale load cells are available in multiple capacities and configurations, including NTEP-certified models for legal-for-trade weighing.
What to Look for in Truck Scale Load Cells
Selecting the correct truck scale load cell is essential for accuracy, durability, and reliable long-term performance. Key factors to consider include load capacity, environmental protection, output signal, and certification.
• High Load Capacity – Truck scale load cells are designed to handle tens of thousands of pounds per load cell, depending on the scale design.
• Environmental Protection – Sealed load cells help protect against moisture, dirt, and corrosion in outdoor installations.
• NTEP Certification – NTEP-approved load cells are required for legal-for-trade truck scale applications.
• Stable Output Signal – Consistent mV/V output ensures accurate readings across the entire scale system.
How Truck Scale Load Cells Work
Truck scale load cells convert mechanical force into an electrical signal that represents weight. When a vehicle drives onto the scale, the load cells compress under the applied force and generate a proportional electrical output.
In most truck scale installations, multiple load cells are installed beneath the platform to evenly distribute the load and maintain measurement accuracy. Proper installation and calibration are essential to achieving consistent, repeatable weighing results.

Truck Scale Load Cell FAQs
How many load cells does a truck scale use?
Most truck scales use multiple load cells, typically between 4 and 12, depending on the size and design of the scale. Each load cell supports a portion of the total vehicle weight to ensure accurate measurement across the entire platform. In the case of a mechanical truck scale, the typical configuration incorporates only a single load cell.
Are truck scale load cells legal for trade?
Truck scale load cells used in commercial applications must be NTEP certified to be legal for trade. NTEP certification ensures the load cell meets accuracy and performance standards required for commercial weighing.
What type of load cell is used in truck scales?
Truck scales commonly use high-capacity double-ended beam or rocker column load cells. These designs are well suited for heavy loads and help maintain accuracy even when vehicles are not perfectly centered on the scale.
What capacity load cell do I need for a truck scale?
The required load cell capacity depends on the scale design, total scale capacity, and number of load cells used. Truck scale load cells are typically rated well above the expected load to provide safety margin and long-term durability.
Do truck scale load cells need environmental protection?
Yes. Truck scale load cells are often installed outdoors and exposed to moisture, dirt, and temperature changes. Sealed or stainless steel load cells help protect against corrosion and extend service life.
How long do truck scale load cells last?
With proper installation and maintenance, truck scale load cells can last the life of the truck scale. Factors such as environmental conditions, traffic volume, and overload protection all impact load cell lifespan.
Can truck scale load cells be replaced individually?
In many cases, individual load cells can be replaced without replacing the entire scale system. However, proper calibration is required after replacement to ensure accurate weight readings.
Why is proper calibration important for truck scale load cells?
Calibration ensures that all load cells in the system work together accurately. Improper calibration can lead to inconsistent readings, reduced accuracy, and potential compliance issues in legal-for-trade applications.
