Identification System eliminates transducer setup errors.
Press Release Summary:
T-ID(TM) and IEEE 1451.4 TEDS compliance use identification module that enables both analog measurement signal and transducer data, stored in digital format, to be retrieved without extra wiring. In T-ID(TM) system, each sensor has ID number that is recognized by integrated database software and can automatically configure amplifier for taking measurements. When using TEDS system, all data needed to configure measurement system is stored in transducer chip.

System Makes It Easy to Identify Transducers
Marlborough, MA - January 15, 2004 - HBM has introduced two intelligent transducer identification systems to help eliminate potential errors caused by manually entering parameters when configuring a measurement system. HBM's T-ID(TM) (Transducer Identification) and IEEE 1451.4 TEDS (Transducer Electronic Data Sheet) compliance use an identification module that enables both the analog measurement signal and the transducer data, stored in digital format, to be easily retrieved without any extra wiring ("Zero-Wire-Technology").
In the T-ID(TM) system, each sensor has a unique ID number that is recognized by HBM's integrated database software and can automatically configure the amplifier for taking measurements. This database can either reside locally or be centralized on the user's local area network. The T-ID(TM) module is either included in the sensor cable or is available as a chip that can be bonded to the test object directly before the strain gage measuring point. When using the TEDS system, all the data needed to configure the measurement system is stored in the transducer chip. This file system has a format and hierarchy that complies with the international IEEE 1451.4 standard and can be used either with HBM's software or stand-alone with the amplifiers. The TEDS identification module can be fitted into the transducer housing, or placed in the cable or connector Both transducer types feature identical connections and amplifier hardware requirements and can be used interchangeably with HBM's MGCplus amplifiers. HBM has applied for a patent for its "Zero-Wire-Technology" that is used with both transducer identification systems. The introduction of these systems will allow engineers to connect transducers and start taking accurate measurements with minimum delay.
Currently, traditional transducers have to be set up by manually entering the correct parameters into the amplifier system to convert measurements into physical units. During this stage, input errors can easily occur leading to measurement errors that may not be detected. Using intelligent transducers largely eliminates this error source. Connector plates that can read the T-ID(TM) or TEDS transducer data are available for HBM's modular MGCplus amplifier system. Catman®4.5, the latest version of HBM's data acquisition software, is loaded with the transducer database used with the identification systems.
