What is the electric beam limiter

The beam limiter is divided into automatic, electric and fully automatic, so what is the electric beam limiter? The electric beam limiter is mostly used in fluoroscopy, which is convenient for remote control, and is an essential component for remote control of gastrointestinal bed. The opening and closing of the lead leaf of the electric beam limiter is generally driven by a miniature DC motor. The forward rotation, reverse rotation and running time of the DC motor can be properly controlled to adjust the irradiation field to the required size. The adjustment of the irradiation field of the electric beam limiter can be carried out on the beam limiter or on the operating platform beside the bed. In addition to continuous adjustment, the latter also has various fixed-size irradiation field selection buttons. As long as these buttons are pressed, the motor will drive the lead leaf to move to the selected irradiation field and fix it to meet the specific requirements of photography. The motor is equipped with limit switches at the closed and maximum open positions of the lead leaf. Automatic limit protection. Electric beam limiters specially used for fluoroscopy, especially in fluoroscopy devices equipped with image intensifiers, need to adjust the size of the irradiation field at any time, so there is no need for irradiation field indication and light display. Because the input screen of the image intensifier is circular, the structure of the masking lead leaf generally adopts the lobe type, which can continuously change the diameter of the irradiation field under the operation of the motor. The structure of lead leaf. If you are interested in our beam limiter, please consult. Tel: +8617616362242
