<p>PURPOSE:To obtain the moisture sensitive material which is uniformly adjusted in pore size and to well follow up the fluctuation in the humidity of an atmosphere to be measured by electrically interposing the moisture sensitive material between the moisture sensitive material of the sintered body of porous titania and a pair of electrodes. CONSTITUTION:The moisture sensitive material is electrically interposed between the moisture sensitive material 1 consisting of the sintered body of the titania formed by aggregating the spherical bodies of resin-coated tiania and sintering the same and a pair of the electrodes 2. A pair of the electrodes 2 are formed on both front and rear surfaces of the moisture sensitive material 1 in the form of a thick film and a pair of the electrodes 2 are connected by leads 3 to an AC power source 4 in order to detect the fluctuation in the impedance of this moisture sensitive material 1. The relative humidity in the atmosphere to be measured is determined from the fluctuation in the impedance measured by placing the moisture sensitive element in the atmosphere.</p> |
