Abstract
Abstract The unique signal generating characteristics of a sensing transducer are defined by integrally incorporating an encoded form of the characteristics into the sensing transducer such that the encoded characteristics can be read by a data reader incorporated into a signal conditioner used with the sensing transducer. The encoded data is incorporated as an inseparable part of each operable sensing transducer by being molded or otherwise formed into a connecting cable of the sensing transducer or engraved or otherwise formed onto the barrel of a connector plug for interconnecting the transducer to the signal conditioner. The encoded data portion of the cable is passed through a reader externally mounted on the signal conditioner, or the encoded data on the barrel of a connector plug is read as the connector plug is inserted into a connector socket on the signal conditioner.
