SYSTEM FOR MONITORING OVERHEATING WITH REMOTE INFORMATION READING Russian patent published in 2011 - IPC G01K7/00 G01K1/12 

FIELD: physics.

SUBSTANCE: system has at least one overheating sensor and a device for reading information on overheating. The overheating sensor is in form of a hermetic housing made from high-thermal conductivity material closed on top by a radiotransparent cover. Inside said housing there is an electrical circuit consisting of a semiconductor element, a thermorelay and an antenna. The semiconductor element is attached to the housing by one end and to the thermorelay by the other. The antenna is connected to the thermorelay. The device for reading information on overheating is a linear transfer detector which remotely reads information on the state of the overheating sensor and consists of a transmitting device tuned to transmit a first harmonic of a probing signal to expose the electrical circuit of the overheating sensor through its radiotransparent cover, and a receiving device which is synchronised with the transmitting device and tuned to receive a second harmonic of the probing signal, and includes a detecting device and a signal processing device for demodulating the second harmonic of the probing signal.

EFFECT: high safety of using different systems.
