摘要： The present publication describes a capacitive humidity sensor and a method for the manufacture of same. The sensor comprises a substrate (1), first (5) and second bottom electrodes (4), which have been fitted close to each other on the substrate (1), an active layer (7), which fills the area between the first (5) and the second bottom electrodes (4) on the substrate (1) and extends to above the top face of the second electrode (4). According to the invention, the sensor further consists of structures (6) connected to the top face of the first electrode (5), made of a conductive material, and being beam-shaped with an upwardly widening section and being placed side by side, the said structures (6) limiting portions (7) of the active layer between themselves from two sides, and a narrow slot (26) being provided between the top faces of the said structures. Owing to its construction, the sensor is not sensitive to touching.

摘要： Disclosed herein is a humidity calibrator device including a base part sealed by plugs, and a replaceable humidity calibrator cartridge. The cartridge contains saturated vapor, saturated salt solution and salt crystals. The cartridge is sealed with a semipermeable membrane and an air-tight protective peel-off foil. The semipermeable membrane, which seals the part of the humidity calibrator cartridge entering the base part of the apparatus provides a separation of the compartment in the base of the apparatus and liquid containing space of the cartridge, allowing permeation of water vapor and preventing permeation of the liquid.
摘要翻译：本文公开了一种湿度校准装置，包括由塞子密封的基座部分和可更换的湿度校准器盒。墨盒含有饱和蒸气，饱和盐溶液和盐晶体。墨盒用半透膜和气密保护剥离箔密封。密封进入设备基部的湿度校准器盒的部分的半透膜提供了设备底部的隔室和容器的液体容纳空间的分离，允许水蒸汽渗透并防止水分渗透液体。
