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
The device can be soldered directly on to a printed-circuit
board or fastened with 3 mm bolts.
Solderability: ≤240 °C; ≤4 s.
Resistance to heat: ≤240 °C; ≤4 s.
ROBUSTNESS OF TERMINATIONS
Tensile strength: 10 N.
