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
QUICK REFERENCE DATA
non-conductive foil, which is covered on both sides with a
PARAMETER VALUE UNIT
layer of gold. The dielectric constant of the foil changes as a Humidity range (RH) 10 to 90 % function of the relative humidity of the ambient atmosphere Capacitance at + 25 °C; 43 % RH; and, accordingly, the capacitance value of the sensor is a 122 ± 15 % pF 100 kHz measure for relative humidity. The foil is clamped between Tan δ at + 25 °C; 100 kHz; 43 % RH ≤ 0.035 contact springs and assembled in a plastic housing. It is Sensitivity between 12 % provided with two connecting pins which fit printed-circuit 0.4 ± 0.05 pF/%RH and 75 % RH boards with a grid pitch of 2.54 mm, provision is also made Frequency 1 to 1000 kHz for fastening with 3 mm bolts. The characteristics are not Temperature dependence + 0.1 %RH/K affected by incidental water condensation on the sensor foil. Response time in minutes It should not be exposed to either acetone or chlorine (to 90 % of indicated RH change at vapours. + 25 °C, in circulating air): Between 10 % and 43 % RH < 3
MOUNTING
Between 43 % and 90 % RH < 5 The device can be soldered directly on to a printed-circuit Hysteresis (for RH excursion ≈ 3 % board or fastened with 3 mm bolts. of 10 % to 90 % to 10 %) Maximum AC or DC voltage 15 V
SOLDERING
