MOISTURE-SENSITIVE ELEMENT OF MOISTURE SENSOR Russian patent published in 2011 - IPC G01N27/22

Abstract RU 2433392 C1

FIELD: physics.

SUBSTANCE: moisture-sensitive element of a gas moisture sensor, containing a nonionic surfactant, e.g. polyglycol ether of fatty acids of general formula R-COO(CH₂CH₂O)₆H, where R is a stearic acid residue, and a solvent, e.g. ethyl alcohol. The new composition of the moisture-sensitive element includes a polyatomic alcohol of general formula C_nH_m(OH)_k, e.g. glycerine C₃H₅(OH)₃.

EFFECT: lower output resistance of the sensor and low inertia of the sensor, which widens the measurement range, including trace moisture measurements.
