Telaire Relative Humidity Sensor HS12SP

Telaire HS12SP is a bulk-resistance type of Relative Humidity (RH) Sensor providing a variable impedance value in response to the adsorbed water within the sensor’s proprietary thin-film polymer. Applied to an interdigitated electrode, the polymer’s chemical functional groups disassociate into ionic groups in the presence of water, increasing the sensor’s electrical conductivity. Excited by a low voltage alternating current, the sensor’s resulting impedance is measured via supporting circuitry.
