On the external sides of the chambers, two coils are arranged opposite each other, between which the ferrite plate can move. Its movement caused by pressurization changes the inductance of the coils in opposite directions, which can be acquired very accurately. Inductive sensors are suitable for particularly low pressures in the measuring range up to 0 to 0.1 mbar = 0 to 10 Pa. The application areas are limited to non-aggressive or inert gases as they occur in heating, ventilation, or clean room technology.
