ABSTRACT
The paper presents the architecture of an interface meant to connect the transducers controlling the underground atmosphere parameters to a computer system based on a microprocessor or a microcontroller. The interface is conceived so as to ensure compatibility with the existing telemeasurement lines and transducers, giving the possibility to connect other transducer types. After stating the technical and functional specifications, the paper synthesized architecture of the interface allows the achievement of a computerized acquisition system, controlled either by a PC or by a PLC, with possibilities of use in other industries where there are hazardous gas emission.
