Abstract
Leak detector of combustible gases with immediate disconnection of the electric current. It consists of an electric gas sensor, a sensor reader and an alarm actuator with two sequential relays that act as follows: when gas is detected in the environment, the electric gas sensor produces a voltage variation in its output, which affects to the alarm actuator that initiates the activation of relay 1 that, in case of being connected to phase, passes a phase-earth current, determined by the absorption resistance, in series, higher than that supported by the differential of the installation, normally calibrated to 30 ma, which immediately produces the tripping of the differential, leaving the whole installation without electric current, and guaranteeing the production of sparks.
