The capacitive sensors can be divided into which types? What are their characteristics?

Capacitive sensors can be categorized into three types based on their operating principles:

  1. Variable Air Gap Type:

    • Characteristics:58彩票 The capacitance is inversely proportional to the distance between the plates. This type is suitable for measuring displacement.

  2. Variable Area Type:

    • Characteristics: The capacitance is directly proportional to the change in the area of the plates. This type is appropriate for measuring linear displacement and angular displacement.

  3. Variable Dielectric Type:

    • Characteristics: This type utilizes different dielectric constants of various media. It detects changes in the dielectric medium and reflects these changes through variations in capacitance. It is suitable for situations where the dielectric constant of the medium changes.
