Abstract:
     This invention relates to a kind of resistance type moisture sensor, resistance of which changes with the relative moisture. It is mainly consisting: ZnCr2O4-LiZnVO4(mo1%)40-98.8,10-0.1, by adding Y2O3, SnO2 to form sintered element, which possesses properties of less volume, better to resist aging, no need of heat cleaning, prolonged life, quick response, less temp. coefficient, suitable range of resistance and high precision of measuring. It can be used as the moisture measuring and controlling elements for cotton mill, meteorology, warehouse and air conditioning systems.
