Abstract
The invention relates to a device for detecting the thickness and crown of plates and strips, belonging to the field of nuclear technology applications. The device comprises a C-frame; two ray source mounted in an upper arm of the C-frame and distributed at an interval along the width direction of a steel plate/strip; two rows of gas-pressurized ionization chamber detector arrays mounted in a lower arm of the C-frame and distributed at an interval along the moving direction of the plate/strip; collimators mounted below the two ray source, the collimators enabling the rays of each ray source to only irradiate to a corresponding row of detectors; pre-amplifier modules connected with the detector arrays; a data collector connected with the pre-amplifier modules; a data processing and displaying computer connected with the data collector; and a cooling water and pressurized air service system and a control system for ensuring system operation and monitoring. The device of the invention is simple in structure and high in dynamic measurement accuracy, and the detectors have the advantages of small temperature drift, irradiation resistance, high spatial resolution, high cost performance and the like.
