Humidity Sensors
Humidity sensors are used to measure the humidity in air, as a fraction of the maximum amount of water that can be absorbed by air at a certain temperature. Under normal atmospheric conditions and a given temperature this fraction can vary between 0 ( absolute dry point ) and 100 (Condensation starting point ). This relative humidity measurement is only valid under the above mentioned temperature and atmospheric conditions, thus making very important the fact that the sensor must not be affected by temperature or pressure changes. As a result it is obvious that Temperature or Pressure Dependent sensing elements, such as Mechanical Devices and Resistive type Sensors, are far behind of the respective non-dependent ones, such as Capacitance sensors. Absorption based humidity sensors provide both temperature and %RH (Relative Humidity) outputs.

Humidity Cells are mainly Capacitance sensors characterized of an excellent long term stability, good resistance to pollutants, precise measurments, high sensitivity, intergangeability and wettability.

Applications Include:

  1. Refrigeration
  2. Drying Processes
  3. Meteorology
  4. Battery-powered systems
  5. OEM assemblies
