Key Differences Between Force Sensors and Load Cells
Force sensors and load cells are both transducers that convert mechanical force into measurable electrical signals, but they differ in design, application, and functionality. Here's a detailed comparison based on definition, primary function and technical characteristics:
1. Definition & Primary Function
Aspect | Force Sensor | Load Cell |
Purpose | Various force types (tension, compression, shear, torsion) | Weight (gravitational force) |
Measurement Axis | Multi-axis (3D force measurement) | Single axis (vertical/unidirectional) |
Output | Force values (N, kN, lbf) | Weight values (kg, lb, t) |
2. Technical Characteristics
Feature | Force Sensor | Load Cell |
Working Principle | Strain gauge, piezoelectric, capacitive, optical, etc. | Strain gauge-based (Wheatstone bridge) |
Dynamic Response | Measure dynamic forces at high frequencies | Optimized for static measurements |
Accuracy | ±0.1%F.S. to ±1% FS (high-end: ±0.03%F.S.) | ±0.01% to ±0.1% FS (legal trade requirements) |
Overload Capacity | 200-500%F.S. | 150%F.S. |
