GSL301 S-Type Tension & Compression Load Cell
The GSL301 is a highly versatile S-beam tension and compression load cell manufactured from premium nickel-plated alloy steel. Supporting bidirectional force measurement across an extensive capacity range of 5kg to 20 Tons, it offers professional-grade precision (±0.02% ~ 0.05% F.S.). Equipped with a robust rubber seal (IP65 protection) and a 4-core shielded cable, GSL301 is specifically engineered for long-term stability and high resistance to off-center loads.
Mechanical Protection Layout
To optimize structural integrity and sealing protection based on capacity, GSL301 features two distinct design variations:
Capacity < 1 Ton
Equipped with **Rectangular Metal Plate Protection** for compact, highly sensitive micro-tension tasks.
Capacity ≥ 1 Ton
Equipped with **Circular Metal Plate Protection** to withstand rugged heavy-duty industrial force limits.

Frequently Asked Questions
1. How do I choose between Eye Bolts and Universal Joints?
If your application exerts a straight, purely vertical pull, standard Eye Bolts (吊环) are ideal. However, if there are any lateral or side forces, you must use Universal Joints/Rod Ends (万向节) to absorb the non-axial loads and protect the cell from shearing damage.
2. Why does the GSL301 have different metal cover designs depending on capacity?
Sensors rated under 1 Ton feature a rectangular metal cover to minimize footprint and maintain sensitivity for low-range calibration. High-capacity versions (1 Ton and above) utilize a robust circular plate cover to handle extremely high loads without compromising structural sealing.
3. Can I connect GSL301 directly to a PLC without a transmitter?
No, standard PLCs cannot directly read the raw mV signal of a load cell without a specialized weighing module. We strongly recommend bundling the GSL301 with our **GT202 single-channel anti-interference transmitter** to convert the output to a stable 4-20mA or 0-10V analog signal.
4. Is GSL301 suitable for high-vibration conveyor belts?
Yes. GSL301 is engineered with high repeatability and excellent resistance to off-center loads. Its robust alloy steel structure and rubber-sealed protection absorb mechanical vibration, ensuring stable data for packaging and belt scales.
