DEVICE FOR ASSESSMENT OF EGG SURFACE TEMPERATURE AND EGG POSITION Russian patent published in 1997 - IPC

FIELD: agriculture; poultry farming. SUBSTANCE: device has two transducers 1 and 2 sensing temperature of the surface of egg 7. The outputs of the transducers are connected to the first and second inputs of recording unit 3 of the control system. The device is provided with transducer 4 sensing contact between brood-hen body 4 and egg 7. Transducer 4 is located in the center under the litter. The control system is provided with switch 5 of temperature transducers 1 and 2 and control unit 6. The first and second inputs of the control unit are connected to the output of transducer 4 and the first output of the recording unit. The third and fourth inputs of the recording unit are connected to the first output of control unit 6 and output of switch 5 of temperature transducers 1 and 2. The switch input is connected to the second output of control unit 6. Temperature transducers 1 and 2 may be positioned in the opposite ends of the smaller axis of symmetry of the maximal ellipsoid section of egg 7. EFFECT: higher incubation efficiency. 3 dwg
