Title: Microwave moisture measuring system
Inventor: CORNETET WENDELL HILLIS
IPC: G01N22/04
Filed: 1968-02-19
Abstract: 1,212,932. Measuring moisture content. INDUSTRIAL NUCLEONICS CORP. Feb. 19, 1968 [April 3, 1967], No.8074/68. Headings G1A and G1N. The percent moisture content of a flowable bulk material 15, e.g. tobacco, cotton, flour or grain, is determined by passing micro-wave energy through the material from a transmitting antenna 30 to a receiving antenna 32 to obtain a first signal dependent on the moisture content, and by passing nucleonic type radiation, e. g. beta, gamma or bremsstrahlung radiation, through the material from a gauge 66 to obtain a second signal dependent on the mass of the material, the two signals being applied to a ratio circuit 65 to derive an output representative of the percent moisture content. The signal may be applied to a meter 68 for direct reading, or may be used for automatic control of moisture content. The micro-wave energy originates from an oscillator 40, a portion of the energy passing to antenna 30 being measured by a detector 44 to derive a signal which operates via a control loop 45, 46, 48 to stabilize the energy level. The received energy passes to a detector 54 via an attenuating system including a PIN diode. The detected signal functions via a comparator and bias control circuit 55 to maintain the detected signal level constant by adjustment of the diode attenuation, whereby the bias signal applied to the diode provides a measure of the moisture content. Temperature compensation is effected by controlling detector 54 by a signal from a thermo-electric detector 70. Errors due to the scattering of microwave energy from the surface of the material are avoided by detecting scattered radiation by an antenna 35 and detector 60 to obtain a signal which . is combined with the bias signal in circuit 64. The nucleonic radiation may be obtained from Strontium 90 and Krypton 85 in the case of beta rays, and from Americium 241 and Cesium 137 in the case of gamma radiation. A scintillation detector or ionization chamber may measure the radiation passing through the material. The material may be conveyed to the measuring apparatus by a non-metallic conveyer or closed conduit. The radiation paths from the micro-wave and nucleonic measuring arrangements are inclined with respect to a normal at the material conveyer so that they may pass through a common measuring zone, Fig. 1 (not shown).
