The construction and characteristics of sorption polymeric relative hu
midity sensors, sorption SiOx microhumidity sensors and condensation-t
ype (dew-point) sensors are compared. The characteristics of the senso
rs are examined in a dew-point range from -80 to +20 degrees C. An int
egrated multifunctional humidity sensor for measurements in a wide hum
idity range at different conditions has been developed. The sensors ar
e intended for use in various branches of industry, and in scientific
research. (C) 1997 Elsevier Science S.A.
