WINFOSS-P6 micrometer adopts Finland VAISALA capacitive humidity sensor, capacitive medium is polymer collection film, so it is often called polymer film humidity sensor, the linear in the low humidity segment is better, it is composed of the upper and lower plate, the middle is polymer collection medium, the medium is Finland VAISALA company patented products, Polymer collection film is an organic medium, with the advantages of rapidly absorbing water and releasing water, but also an insulating medium when the water vapor molecules in the measured gas enter the polymer collection film through the upper plate, very few water vapor molecules cause large changes, and the change of capacitance is proportional to the relative humidity, which indicates that the change of capacitance is proportional to the humidity of the gas.
