Apparatus for determining the level and profile of a material
Patent
·
OSTI ID:4308198
An apparatus for determining the level and profile of materials, in which a collimated radiation source has a servo and produces a beam of hard electromagnetic radiation reflected from an irradiated zone on a surface being gaged and picked up from a receiving zone by a collimated detector also having a servo is described. The two servos are controlled by individual amplifiers in accordance with signals received from an electrically connected means for sensing relative alignment between the irradiated and receiving zones, one amplifier accepting signals corresponding to the amount of misalignment between the two zones with only one sign, according to the magnitude of which it brings down the speed of the associated controlled servo, and the other amplifier accepting signals corresponding to the amount of misalignment between the two zones.
