In the world of precision weighing, S-type load cells have earned a reputation for their reliability and versatility. Recognizable by their compact, S-shaped design, these load cells are widely used in both tension and compression applications, making them one of the most flexible choices for industrial weighing systems.
In this article, we’ll explore what makes S-type load cells unique, their common applications, and why leading models like the Coti Global CGSB/ CGSB-1 series and the Rice Lake RL20000I/RL20001 series are trusted across industries.
What is an S-Type Load Cell?
An S-type load cell (sometimes called an “S-load cell”) is a transducer designed to measure force through both tension and compression. Its S-shaped body gives it excellent strength-to-size efficiency, allowing it to handle high loads while remaining compact enough to fit in a variety of systems.
Most models, like the Coti Global CGSB or Rice Lake RL20001, feature threaded mounting holes at both ends. This makes them easy to integrate into mechanical or suspended weighing setups without complex modifications.
Key Benefits of S-Type Load Cells
S-type load cells are popular because they bring together strength, adaptability, and precision:
Versatile Use: Designed for both tension (pulling) and compression (pushing) measurements.
High Accuracy: Typical error margins as low as ±0.02% for reliable, repeatable results.
Durability: Alloy steel bodies with nickel plating resist corrosion and wear.
Environmental Protection: Many are IP67 sealed, keeping out dust and moisture.
Wide Capacity Range: From low-capacity models around 100 lb to heavy-duty 20,000 lb units.
S-Type Load Cell Applications
Because of their compact design and dual measurement capability, S-type load cells are used in industries such as:
Hopper and Tank Weighing – Perfect for suspended systems measuring bulk material.
Material Handling – Ensuring accurate load monitoring in conveyors and batching systems.
Crane and Tension Systems – Measuring suspended loads safely and precisely.
Testing Environments – Widely used in research, force measurement, and quality control.
Coti Global CGSB Series: A Proven Example
The Coti Global CGSB series exemplifies the durability and flexibility of S-type load cells. With capacities ranging from 100 lb up to 20,000 lb, this series covers nearly every weighing application.
Highlights include:
Alloy steel construction with nickel plating.
NTEP certification and FM approval.
IP67 sealing for harsh environments.
Whether you need a CGSB 500 for smaller applications or a CGSB 20K for heavy-duty operations, this series has the range to meet your needs.
Rice Lake RL20001 Series: Trusted Industry Standard
The Rice Lake RL20001 series is another outstanding family of S-type load cells. Known for their precision engineering and long-term reliability, these load cells are widely used across industries such as agriculture, shipping, and manufacturing.
With capacities from 1K to 20K, plus features like 150% overload protection and rugged alloy steel design, the RL20001 series is built for accuracy and durability in real-world conditions.
Final Thoughts
S-type load cells deliver the versatility, strength, and precision that industries rely on for critical weighing applications. Whether in suspended tanks, crane systems, or industrial scales, they provide the balance of compact design and high performance that few alternatives can match.
Trusted models like the Coti Global CGSB series and Rice Lake RL20001 series highlight the best of what S-type technology offers: reliable measurements, long-term durability, and the confidence to keep operations running smoothly.
If you’re evaluating S-type load cells for your application, consider these series as proven solutions to meet your weighing needs.
