• The Smartec humidity sensor is a two
terminal capacitor, which increases in value as water molecules are
absorbed into its active polymer dielectric. The capacitor plates consist
of a base plate and a water permeable platinum top plate.
Two version are available HS07 and the smaller HS08A. The SMT-HS07c has
• linear 0 -100% RH.
• High performance.
• Long Term Stability.
• Fast response.
• Close tolerances.
• Reliable construction.
• Low cost.
• Air conditioners.
• Climate control for green houses.
• Storage and warehouses.
• Meteorological applications.
• Food processing.
• Room comfort control.
• Medical applications.
• The sensor are delivered with gold-plated lead wires attached.
Besides the active dielectric, polymers give protection to the base plate, prevent
polarisation and pin holing and generally ruggedise the sensor so that it
can be used in a wide range of hostile environments.
