Abstract
Abstract The single/multiple transducer for measuring physical quantities and variables comprises a multiplexer (2) for selecting the sensors of physical quantities and electric variables by decoding of an address, thereby permitting a single power supply (5), a single counter and a single clock generator to be used in order to enable a plurality of sensors placed in a plurality of locations and to transmit the measurements thereof, each of said sensors detecting its own physical quantity or electric variable.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
119 words
1) A single/multiple transducer for measuring conventional physical quantities and or electric variables, characterized in that it comprises: - one or more sensors for detecting different physical quantities and variables, - a multiplexer for enabling and selecting one of the sensors of physical quantity and electric variable corresponding to a coded address assigned thereto, -- a clock generator, - a counting and timing circuit for forming the address to be delivered to the multiplexer in order to select one of the externally connected sensors, - a power supply for delivering the operating voltage to the above mentioned components, and - a line for supplying and delivering the signal proportional to the physical quantity or variable detected by the sensors.
Claim 2
Dependent Claim
119 words
1) A single/multiple transducer for measuring conventional physical quantities and or electric variables, characterized in that it comprises: - one or more sensors for detecting different physical quantities and variables, - a multiplexer for enabling and selecting one of the sensors of physical quantity and electric variable corresponding to a coded address assigned thereto, -- a clock generator, - a counting and timing circuit for forming the address to be delivered to the multiplexer in order to select one of the externally connected sensors, - a power supply for delivering the operating voltage to the above mentioned components, and - a line for supplying and delivering the signal proportional to the physical quantity or variable detected by the sensors.
Claim 3
Dependent Claim
47 words
2) A single/multiple transducer as claimed in claim 1, characterized in that it comprises a circuit for generating the coded addresses associated to the sensors, said circuit, once it as been programmed by the operator or installer, automatically generating the addresses of the sensors to be enabled.
