发明名称 PROCESS FOR REMOTE SIGNALS TRANSFERING AND ITS USE FOR DETECTION AND/OR CONTENT MEASURING OF COMBUSTIBLE GAS OF AN ATMOSPHERE
摘要 A process of remote transmission of signals issued by at least one sensor over a transmission line, wherein the power necessary to supply the sensor is transmitted by that line in the form of an alternating current signal of approximately constant intensity, and wherein the line fulfills the triple function of supplying power to that sensor, of transmitting interrogation signals from a central station to that sensor and of transmitting data signals in response to that interrogation signal from the sensor to the central station. A device for incorporating this process is also disclosed.
