APPLICATIONS

• Humidity measurements in electronic

• 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.

MOUNTING

The device can be soldered directly on to a printed-circuit

board or fastened with 3 mm bolts.

SOLDERING

Solderability: ≤ 240 °C; ≤ 4 s

Resistance to heat: ≤ 240 °C; ≤ 4 s

ROBUSTNESS OF TERMINATIONS

Tensile strength: 10 N
