Ring-type force sensors NF167
Features
Ring-type force sensors NF167(also known as ring load cells or spoke-wheel sensors) are designed for high-capacity measurements, making them suitable for heavy-duty applications in industries such as manufacturing, aerospace, and heavy machinery. Below are their key features:
Ring/Spoke Design: Force is evenly distributed across the ring structure, with multiple strain gauges (e.g., 4-8 sets) detecting deformation to minimize stress concentration.
Compact & Low-Profile: Compared to column-type sensors, the ring design saves space, making it ideal for embedded installations (e.g., crane pulleys, bearing housings).
Applications
- Heavy machinery (cranes, hydraulic presses)
- Bridge/structural health monitoring
- Medical testing
