FIELD: physics, signalling.
SUBSTANCE: invention relates to electronic engineering, particularly to alarm systems, and can be used as a device for controlling access to a facility. The electronic sealing device comprises a housing which consists of two electrodes separated by a dielectric insert, which form a capacitive sensitive element which is electrically connected to a power supply, an inductive communication interface coil and an electronic unit for measuring capacitance of the sensitive element, processing and storing information, said components being located inside the housing and connected to each other. The housing has a safety cap made of dielectric material.
EFFECT: high thermal stability of the device owing to exclusion of movable parts in the structure of the sensitive element and enabling installation on thin-walled facility.
