The invention has for its object a device for measuring the slope parameters of a material contained in a cylinder rotated around the axis thereof. This device, which senses radiations generated by radio-isotopes passing through the cylinder and the material contained therein, comprises means 1 generating the said radiations and means 8a, 8b picking up the latter fitted outside the cylinder in such a manner that, during the rotation thereof, the radiation generated by the radio-isotopes passing through the slope of material 5 in at least two separate locations is sensed in a specific point of the cylinder, as well as means for analyzing the signals received by the means sensing said radiation. This device is to be used together with a rotating furnace and particularly a cement kiln.
A device for measuring slope parameters for a loose material contained inside a hollow cylindrical wall which rotated about its axis so that when viewed in transverse cross section the material forms a slope segment in engagement with the inner surface of said wall, said apparatus comprising a radioactive source generating a stream of penetrating radiation;
Apparatus as in claim 9 wherein the radioactive source and the sensors are adjustable along said ring.
