1. A measuring system for determining a chemical or physical property of a gaseous, liquid or solid medium, the system comprising:
- a stationary holding means;
at least one sensor mounted to said stationary holding means to contact the medium, said sensor consisting essentially of means for detecting the chemical or physical property of the medium, means for generating at least one electrical signal having at least one signal properly which provides quantitative information concerning the chemical or physical property to be determined and a one-way, output only sensor interface for output of said electrical signal;
an analyzer unit, said analyzer unit accepting input concerning said electrical signal from said sensor, said analyzer unit having means for processing said signal property to extract said quantitative information; and
a multiple input and multiple output communications network disposed between and connecting said sensor interface and said analyzer unit to transmit said signal property from said sensor to said analyzer unit, said communications network having switching means for connecting together a selected one of said multiple inputs with selected one of said multiple outputs, said network generating an input-output connection for transmitting that signal property, wherein said communications network has a total number of possible input-output connections defining an overall communication capacity which greatly exceeds a communication capacity required for transmission of said signal property alone.

14. A method for determining a chemical or physical property of a gaseous, liquid of solid medium, the method comprising the steps of:
-
mounting at least one sensor to a stationary holding means to contact a medium, said sensor consisting essentially of means for detecting the chemical or physical property of the medium, means for generating at least one electrical signal having at least one signal property which provides quantitative information concerning the chemical or physical property to be determined, and a one-way output only sensor interface for output of said electrical signal;
configuring an analyzer unit to accept input concerning said electrical signal from said sensor, said analyzer unit having means for processing said signal property to extract said quantitative information; and
connecting a multiple input and multiple output communications network between said sensor interface and analyzer unit to transmit said signal property from said sensor to said analyzer unit, said communications network having switching means for connecting together a selected one of said multiple inputs with the selected one of said multiple outputs, said network generating an input-output connection for transmitting said signal property, wherein said communication network has a total number of possible input-output connections defining an overall communications capacity for said communications network which greatly exceeds a communication capacity required for transmission of said signal property alone. - View Dependent Claims (15, 16, 17, 18, 19)
