| Zusammenfassung: | The invention provides a macromolecule resistance humidity sensor and a relative production, wherein the macromolecule resistance humidity sensor comprise a porous ceramic base which upper and lower surfaces are respectively distributed with upper and lower surface electrodes, the surface electrodes are connected with lead wires, the holes on the porous ceramic base are immerged with humidity-sensitive medium, to form a solid humidity sensitive membrane. The inventive macromolecule resistance humidity sensor has simple and reliable production, low cost, non special device demand, batch production application, high output linearity, little humidity hysteresis return difference, high temperature resistance, high consistence, high stability for long time and better chemical gas resistance. |
