Abstract
A system for measuring at least one parameter is provided. The system includes a control logic arrangement powered by a power source, and an intrinsically safe barrier operatively connected to the control logic arrangement, and also powered by the same power source. The intrinsically safe barrier is adapted to be operatively connected to at least one sensor which is also powered by the same power source. The sensor is configured to communicate data representing a parameter to the control logic arrangement via the intrinsically safe barrier. In one embodiment, the control logic arrangement, the intrinsically safe barrier and the sensor are galvonically isolated from external components and/or provided in one enclosure.
