Overview
2322 691 90001 Vishay BCcomponents Humidity Sensor APPLICATIONS • Humidity measurements in electronic hygrometers for domestic use • Self-regulating air humidifiers, etc.
DESCRIPTION This capacitive atmospheric humidity sensor consists of a non-conductive foil, which is covered on both sides with a layer of gold.
The dielectric constant of the foil changes as a function of the relative humidity of the ambient atmosphere and, accordingly, the capacitance value of the sensor is a measure for relative humidity.
The foil is clamped between contact springs and assembled in a plastic housing.
It is provided with two connecting pins which fit printed-circuit boards with a grid pitch of 2.
54 mm, provision is also made for fastening with 3 mm bolts.
The characteristics are not affected by incidental water condensation on the sensor foil.
It should not be exposed to either acetone or chlorine vapours.
