HUMIDITY Sensor

DSHS07 - Smartec bv (Smartec bv)

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. The sensor will be delivered with gold-plated lead wires attached. Besides the active dielectric, polymers give protection to the base plate, prevent polarisation and pinholing and generally ruggedise the sensor so that it can be used in a wide range of hostile environments.
