Unformatted text preview: apply at a supply pressure of 15 kPa (150 mbar). One possible value for the distance between sensor and lid is between 2 – 4 mm. At this distance, a signal pressure of 0,3 – 0,4 kPa (3 – 4 mbar) is produced. This output signal can be amplified with the help of suitable pressure amplifiers.
