  • Micro-wave hygrometer
    Patent number: 4103224
    Abstract: A micro-wave hygrometer having a dielectric resonator, a micro-wave transmitter and receiver to and from the dielectric resonator, and an electro-static shield surrounding said dielectric resonator and a support supporting the dielectric resonator at the portion where the electric field is small. The humidity of air and/or gas can be measured by measuring the value Q of the resonator for micro-wave energy, or the loss of micro-wave energy.
