Frequently Asked Questions
What is the difference between NTEP and OIML approval for load cells?
NTEP (National Type Evaluation Program) is the US standard for legal-for-trade weighing devices, while OIML (International Organization of Legal Metrology) is an international standard. Both ensure accuracy and reliability, but NTEP is required for commercial scales in the US. Many load cells carry both approvals for global use.
How many load cells do I need for a truck scale?
Typically, a truck scale uses 4 to 8 load cells, depending on the size and capacity. A standard 70-foot scale often uses 8 cells (one per corner of each section). For smaller scales, 4 cells may suffice. Always follow the manufacturer’s recommendations for proper weight distribution.
Can I replace a load cell myself?
While physically replacing a load cell is straightforward, proper calibration and alignment are critical for accuracy. We recommend having a professional technician perform the replacement and recalibration, especially for legal-for-trade scales. Incorrect installation can lead to inaccurate readings and safety issues.
What is the typical lifespan of a truck scale load cell?
With proper installation and maintenance, high-quality load cells can last 10-20 years or more. Factors like environmental conditions, overloading, and lightning strikes can shorten lifespan. Regular calibration checks help monitor performance.
Do I need a stainless steel load cell for outdoor use?
Stainless steel offers superior corrosion resistance and is recommended for outdoor or washdown environments. Alloy steel cells with protective coatings can also work but may require more maintenance. For pit scales prone to moisture, stainless steel is the safer choice.
