A Comprehensive Analysis: Why We Need C6 Instead of C3 Load Cells?

Release time:2023-07-06 08:13

Load cells are essential components in various industries, playing a crucial role in measuring force and weight. Among numerous load cell classifications, C3 become increasingly popular due to their accuracy compliance with trade regulation and economic cost. However, the demand for greater precision and adaptability has led to the rise of C6 load cells over their C3 counterparts in some applications. This article explores the reasons behind this shift, discussing the advantages of C6 load cells and their applications in various industries.

Higher Accuracy and Greater Resistance to Environmental Factors

The primary reason for choosing C6 load cells over C3 load cells is their superior accuracy. C6 load cells offer an improved accuracy class, with a lower error margin of ±0.01% compared to C3's ±0.02% error margin. This enhanced precision is crucial for industries such as pharmaceuticals, aerospace, new energy, semiconductor and automotive manufacturing, where even the slightest inaccuracies can lead to considerable financial losses and product recalls.

C6 load cells exhibit better resistance to environmental factors such as temperature fluctuations and humidity. Their temperature compensation range allows them to maintain accurate measurements even in extreme conditions, making them ideal for use in industries such as chemical, oil which related to extreme temperature.

Improved Adaptability


C6 load cells also offer adaptability in terms of installation and customization. They are available in various configurations, such as single-point and compression type, allowing them to cater to a wide range of applications. This versatility makes them suitable for use in industries with diverse measurement requirements, including logistics, packaging, and food processing.

Higher Compliance with Industry Standards


C6 load cells stand for a higher compliance with international industry standards OIML. This ensures that they meet rigorous quality and performance benchmarks. As industries become more regulated, the need for load cells that comply with these stringent standards will only increase.

With the above features, C6 load cells provide a compelling alternative to C3 load cells. As industries continue to demand greater precision and adaptability, the adoption of C6 load cells is expected to grow.

C6 load cell in advanced application fields and scenarios

What we all know is load cell is a key component for a scale or other application. The most common accuracy is C3. But we found C3 load cells are not always the best ones which cater to the customer in key processes of some advanced application fields and scenarios. The C6 load cells with the above advantages will be able to perform better in these areas.

1. Precision weighing control

In Li-ion Battery or pharmacy industry, the match proportion is key to improving performance and quality. The volume of some matched material is very small and powder, therefore the matching process accuracy is critical. Weighing control system with C6 load cell is the only way to address this challenge in an effective and economic aspect.

2. Identifying missing components

If a package or part is supposed to have a specific number of components, but one of them is missing, then how to find it and avoid impacting delivery efficiency? We need a smart way to solve the problem. Traditional manual inspection or advanced machine vision inspection can’t fulfill this request. But the C6 load cell can identify any missing by detecting weight change down to 0.2 gram.

3. Detecting gross defects

Significant defects, such as large voids or inclusions in manufacturing, may result in a noticeable weight difference compared to a defect-free part. Checkweigher which applies C6 load cell can identify material-related issues or discrepancies by measuring its weight and comparing it to the expected value.

4.Monitoring irrigation process

To reduce excessive water use and improve productivity, scientists and experts are building more and more accurate irrigation control system. ZEMIC C6 load cell can make the system even detect weight change from several water drips, therefore it helps agriculture research labs to optimize planting of every crop. Compared to a flow meter, load cell is more adaptive for medium and economical.

5.Wind tunnel test

Keeping a balance between steady and reducing drag force from rolling resistance is an important goal in race car industry. The key aerodynamic parts related to these points include Splitter and rear wing which generate downforce for the car. In order to optimize these parts’ design, car developing team may measure the force of each variant in wind tunnel test and choose best one according to their model. C6 load cell can provide good accurate measurement and general reliability for this application.


Overall, as a higher-level force measuring components, C6 load cell will be used in more application to ensure comprehensive and accurate assessment. ZEMIC provide new approved C6 class load cells now. Please don't hesitate to contact local sales representatives for details.
