OPTICAL CABLE SEAL Russian patent published in 2004 - IPC

FIELD: iron-mongery engineering.

SUBSTANCE: optical seal has cup with an insert in it made of transparent material, forming a body, inside of which ends of connecting body are fixed, which body is connected to protected object, and at least one information element, while in body elements are made for even insertion of automated device for reading optical image of information element. Inner bottom of cup is made with through channels for letting ends of connecting body through them and is provided with elements for rigid fixing of connecting body in these channels, while cup and insert are fixed relatively to one another with impossible dismounting without irreversible deformation and destruction of at least one of said parts, and as information elements, optical images of which are calculated separately, a portion of inner surface of insert is used and one of portions of cup surface protected from outside effects and accessible for optical probing radiation.

EFFECT: higher efficiency.
