FIELD: engineering of technological transmitting sensors with wireless communication channels for measuring technological parameter of industrial process.
SUBSTANCE: sensor contains sensitive element, connected to first electronic circuit, which is connected to second electronic circuit by non-contact electromagnetic channel and separated from it by wall in the body, forming hermetically packed hollow. Two-wired technological control contour provides power to circuits. Non-contact electromagnetic channel may be represented by radio frequency channel, capacity or inductive link. Second electronic circuit may be located inside the body or outside it, and may receive power through non-contact electromagnetic channel from first electronic circuit.
EFFECT: decreased number of connections in the body of transmitting sensor, provision of high flexibility during mounting.
