Abstract
PURPOSE: To obtain an element of superior durability and reliability by press-bonding a metal mesh electrode within specific mesh range to both sides of a fluorine- resin-based ion exchange film, having an exchange group to specific extent, or an ion exchange porous film based on the same resin.
CONSTITUTION: To both sides of a fluorine-resin-based ion exchange resin, having a 0.5W5mlq/g(dry resin) ion exchange group shown by formula I or II (X represents hydrogen, metal atom or ammonium group.) or porous film 1 base on the same resin, electrode 2 of 100W400 meshes wire-netting made of stainless-steel, Ni or plate with anticorrosive metal is bonded by pressing. Further, load wire 3 is connected to electrode 2 to form a humidity and dew sensing element of ≥50% electric resistance variation between the 100% relative humidity point and dew point. Since the resin is anchored in electrode 2, the effective part of the sensor can be protected from dirt and dust. Fluorine resin is chemically and thermally stable and its exchange group amount is proper; and the electric resistance variation is linear to variation in humidity and never changes in aging. Thus, element function can effectively be displayed by a switching system.
