♥Thin Film Resistor Pressure Sensor:

  • Principle: Measures pressure-induced variations
  • Application: Primarily used for pressure detection and control
  • Advantages: Simple design, high sensitivity, long service life
  • Features: Flexible, thin, tolerant to overload without damage

Strain Gauge:

  • Principle: Measures strain-induced variations
  • Application: Mainly used for strain measurement and structural monitoring
  • Advantages: Provides precise measurement results
  • Features: Relatively complex design, rigid, thicker in size


  • Sensitivity: Both high, with strain gauges potentially more sensitive to subtle changes
  • Structural Design: Thin film resistors are simpler, while strain gauges are more complex
  • Application Range: Pressure vs. strain measurement
  • Characteristics: Thin film resistors offer flexibility, whereas strain gauges are more rigid
  • Precision: Strain gauges provide more accurate measurement results

♥ Each sensor has its own unique characteristics suitable for different applications. Which sensor do you prefer?
