FIELD: electricity. ^ SUBSTANCE: sensor is designed to confine an emergency situation related to damage of any technological vessel of transport networks of fluid products. The sensor, in which a sensitive element is an insulated conductive material arranged in the form of a screening shell - placed in a labyrinth form along the surface of the controlled vessel, which represents a wire line for transmission of a control current from a terminal device - a semiconductor diode to a unit to control switching equipment of an electromagnet self-closing valve and an emergency decompressor (a device for fluid product pumping), the cross section of each strand in a screening shell is calculated using the formula. ^ EFFECT: reliability improvement. ^ 3 dwg |
