5.2 TEDS transducer identification

TEDS stands for "Transducer Electronic Data Sheet". An electronic data sheet
is stored in the transducer as defined in the IEEE 1451.4 standard, making it
possible for the measuring amplifier to be set up automatically. A suitably
equipped amplifier imports the transducer characteristics (electronic data
sheet), translates them into its own settings and measurement can then start.
At the gray connection (to ground at black), there is a digital identification
system available. The basis for this is a 1−wire EEPROM DS2433, made by
Maxim/Dallas.
HBM provides you with the TEDS Editor for storing your data. This is a
component part of the MGCplus Setup Assistant software (see the TEDS
operating manual "TEDS data memory in the transducer" on the Internet at
www.hbm.com/TEDS).
The Editor also makes it possible to manage the different user rights to
protect the fundamental transducer data from being inadvertently overwritten.
Content of the TEDS memory as defined in IEEE 1451.4:
The information in the TEDS memory is organized into templates which are
prestructured to store defined groups of data in table form. Only the entered
values are stored in the TEDS memory itself.
The amplifier firmware assigns the interpretation of the respective numerical
values. This places a very low demand on the TEDS memory.
The memory contents are divided into four areas:
Area 1:
An internationally unique identification number (cannot be changed).
Area 2:
The base area (basic TEDS), to the configuration defined in standard
IEEE 1451.4. The transducer type, the manufacturer and the transducer serial
number are contained here.
Area 3:
Data specified by the manufacturer are contained in this area:
These specify
− the transducer type,
− the measured quantity,
− the electrical output signal,
− the required excitation.
