Title:
HUMIDITY MEASURING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/203860
Kind Code:
A1
Abstract:
Provided is a humidity measuring apparatus that is capable of, when the humidity of gas is to be measured by the humidity measuring apparatus that uses a thermal humidity detection element, highly accurately measuring the humidity of the gas even in an environment where the gas to be measured vibrates. The humidity detection element is arranged in a space offset from the extension line of a pressure introduction passage in a storage chamber or a space formed on the inner side of a member that is provided to the extension line of the pressure introduction passage in the storage chamber, so that the gas introduced into the pressure introduction passage through a pressure inlet makes a turn at least once before the gas reaches the humidity detection element.
