Intrinsically safe data network

摘要

An intrinsically safe data network, such as one defining a system for acquiring and transferring data from inside a hazardous zone at an oil or gas well to outside the hazardous zone, includes a fixed number of at least one data signal conductor and a fixed number of at least one intrinsic safety barrier forming part of the overall network that allows for the use of more transducers than there are intrinsic safety barrier(s).
