Abstract: This invention disclosure describes an intelligent sensor system in which different types of sensors are connected to a network communication bus. Analog and digital signals are transferred bi-directionally on the common communication bus between the distributed sensors and an application specific controller referred to as a bus converter/controller module (BCM). The traditional analog type sensors are connected to the communication bus through interface devices referred to as transducer-to-bus interface modules (TBIM). The TBIM provides sensor identification, self-test and data correction functions.
