Inductive Measurement Method

Inductive Measurement Method

An inductive measurement system consists of two pressure chambers which are separated from each other by a highly elastic measuring membrane. A coil is attached on each side of the measurement cell. Due to the different pressures generated in the two chambers, the elastic membrane flexes to one side, according to the pressure difference. The inductance of both coils changes accordingly, making it possible to measure an output signal which is proportional to the respective pressure difference.


  • Wear-free operation
  • Not affected by soiling / dust
  • Robust mechanical design


  • Low pressure measurement requires large membranes
  • Slow reaction to fast pressure changes
  • Dependent on mounted orientation
