Claim:
1. A communication interface, at least partially enclosed, for a sensor which includes a sensing strip, provided to be used in a detection device, in particular for leakage detection in an explosive atmosphere, having a plurality of sensors, comprising: at least one upstream communication port, configured for receiving an interrogation signal from upstream of said sensor and transporting it to the sensing strip, and receiving from said sensing strip a response signal and transporting it to upstream of the sensor; at least one downstream communication port, configured for transporting an interrogation signal to downstream of said sensor; at least one sensor short-circuit switch, displaceable between an open position in which the upstream communication port is linked to a port for communication with the sensing strip of the sensor, and a closed position in which the upstream communication port is disconnected from said port for communication with the sensing strip of the sensor and connected to the downstream communication port; at least one control circuit, configured for controlling said at least one short-circuit switch, which is arranged so as to maintain said short-circuit switch:
