Omega Air, Ljubljana, Slovenia: The nominated product is an electronic pressure drop indicator used to monitor air filters in compressed air systems. The change in pressure is recorded in the conventional way with the aid of a membrane by the displacement of a magnet attached to a pre-tensioned spring. What is new is the positional displacement of the magnet. For the first time the displacement of a drop is now capacitively registered from a ferrofluid, which is a fluid that can be magnetized. This method is extremely accurate and results in low energy consumption, which in turn makes it possible to power the device by battery, independently of the mains.
