MOISTURE METER Russian patent published in 1995 - IPC

FIELD: analytical instrumentation engineering. SUBSTANCE: moisture meter includes wet and dry resistance thermometers, tank of wet thermometer manufactured in the form of two vessels placed one above other and provided with vertical tube dropped from upper vessel into lower one. Lower vessel is surrounded by radiation protection coupled to aspiration channel, it includes aspirator. Resistance thermometers are separated from case of moisture meter by thermal insulating spacers. Upper vessel of tank of wet thermometer is produced with developed side surface, for instance in the form of sprocket in cross-section coupled tight to bottom and cover. Case of upper vessel is separated from thermal insulating case of moisture meter by air gap communicating with aspiration channel. Heat conductive partition shaped in section, for instance star-like, connected to bottom and cover with small gaps is placed into lower vessel. There is hole in side wall of lower vessel located somewhat above level of lower cut of tube communicating upper and lower vessels. Upper vessel of tank of wet thermometer is provided with pipe union with end-cap. EFFECT: enhanced reliability, expanded application field. 4 cl, 4 dwg
