DESCRIPTION

Maximum AC or DC voltage

Storage humidity range (RH)

Ambient temperature range:

operating

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

0 to 100

0 to +85

°C

storage

−25 to +85

Drop test:

height of free fall

Mass

≈1.3

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.
