Introduction
Choosing the right high load force torque sensor (200kN level) is critical for industrial applications such as heavy robotics, automated assembly lines, and mechanical testing systems.
Unlike standard sensors, high-load models must deliver extreme durability, precise measurement, and stable performance under heavy stress conditions.
In this guide, we’ll walk you through how to select the right sensor for your application—and avoid costly mistakes.
What Is a High Load Force Torque Sensor?
A high load force torque sensor is a multi-axis measurement device designed to detect:
- Force (Fx, Fy, Fz)
- Torque (Mx, My, Mz)
These sensors are typically used in:
- Heavy industrial robots
- Structural load testing
- Aerospace and automotive validation
- High-force automation systems
For example, a 200kN sensor can measure extremely high forces, making it ideal for demanding industrial environments.
Key Parameters You Must Consider
1. Load Capacity (Most Critical)
Always choose a sensor with a load capacity higher than your actual application needs.
- Typical heavy-duty range: up to 200kN force / 5kNm torque
- Recommended safety margin: 1.5× to 2× working load
👉 Undersized sensors will fail or produce inaccurate data.
2. Accuracy & Precision
Look for:
- Accuracy: 0.1% – 0.5% F.S
- Repeatability: stable under repeated loads
Higher accuracy is essential for:
- Precision assembly
- Calibration systems
- Testing environments
3. Sensitivity (mV/V Output)
Sensitivity affects how clearly the sensor detects force changes.
Typical range:
- 0.5 – 2.0 mV/V
Higher sensitivity = better signal resolution and responsiveness.
4. Multi-Axis Capability (6-Axis vs Single Axis)
For advanced applications, always choose 6-axis sensors:
- Measure force and torque simultaneously
- Enable force-position hybrid control
- Improve automation intelligence
5. Communication Interface
Ensure compatibility with your system:
- RS485 → stable industrial communication
- CAN → robotics systems
- EtherCAT → high-speed real-time control
👉 EtherCAT is preferred for high-end robotics.
6. Software & Integration
A good sensor should include:
- Debugging software
- Real-time force visualization
- Data logging & export
This greatly reduces development time.
7. Mechanical Design & Material
Industrial-grade sensors should have:
- Stainless steel construction
- High overload resistance
Common Mistakes to Avoid
❌ Choosing Based Only on Price
Low-cost sensors often lack stability and durability.
❌ Ignoring Safety Margin
Operating near maximum load reduces lifespan and accuracy.
❌ Overlooking Integration
Without proper software and communication support, integration becomes difficult.
❌ Using Single-Axis Sensors for Complex Tasks
You will lose critical force/torque data.
Application Examples
High load force torque sensors are commonly used in:
- Industrial robotic arms
- Heavy-duty assembly lines
- Aerospace testing systems
- Automotive crash & load simulation
- Precision grinding and polishing systems
Conclusion
Selecting the right high load force torque sensor (200kN level) requires balancing:
- Load capacity
- Accuracy
- Sensitivity
- Communication compatibility
- Software support
A well-chosen sensor will not only improve system performance but also reduce maintenance costs and increase reliability.
