Piezoresistive Measuring Method

Piezoresistive Measuring Method

Piezoresistive measuring systems use the so-called piezoresistive effect. The measuring membrane consists of semiconductor materials, which change their specific resistance as a result of expansion or compression. The proportional pressure difference can then be determined from this change.

Advantages

  • Reduced space and weight
  • Highly sensitive
  • Fast reaction to changes

Disadvantages

  • Can be affected by soiling / dust
  • System is less robust and less attenuated
  • Due to the high temperature dependency an additional compensation is required
