Cascade monitoring apparatus
First Claim
1. An apparatus for monitoring a value of at least one physical parameter at a plurality of points, comprising:
- a plurality of monitoring modules, each module having a logic section and a transducer section associated therewith, whereinthe logic sections are connected in series and identical in their response to a logic signal, whereineach logic section activates its associated transducer section upon receipt of the logic signal, andeach logic section sequentially passes the logic signal to the next module; and
each activated transducer transmits a continuous electrical signal in response to and in correspondence with the physical parameter sensed, for continuously monitoring changes in the parameter sensed;
master electronics for sending an initial logic signal to the module to which it is connected and utilizing the continuous electrical signal for monitoring purposes;
the master electronics including a clock circuit for generating a clock pulse for timing the transfer of the logic signal through each module, andmeans for electrically interconnecting the modules to each other and the master electronics.

Abstract
An apparatus for monitoring the value of one or more physical parameters, the apparatus including a plurality of physical monitoring modules, master electronics, and structure for interconnecting each of the modules and the master electronics. Each module includes a logic section and a transducer section. The logic section receives a logic signal and responds by activating the transducer. The logic signal is passed to the next module according to a clock pulse which is generated from the master electronics. The transducer senses a physical parameter. When activated, the transducer responds to the physical parameter with an electrical signal and communicates the electrical signal to the master electronics which utilizes the electrical signal for monitoring purposes.
