electronic device for the detection of flammable gases.

摘要

apparatus for the detection of flammable gas, comprising a sensor (3) of the type spiral thread in alloy of platinum.when the said sensor (3) is connected to a power supply (1) constant current through a current regulator (2), the said regulator (2) being bound to a unit (4) to control thecurrent of excitation of the sensor (3) and d / a conversion of a correction signal issued by a microprocessor (6) which is linked to it and to which is transmitted the signal output of the sensor (3)after conversion of the same to analog to digital converter by means of an a / d (7) (fig. 1).
