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 start.
At connection PIN 7 (to ground at PIN 2), there is a digital identification system
available. The basis for this is a 1‐wire EEPROM DS2433, from Maxim/Dallas.
HBM provides you with the TEDS Editor for storing your data. This is included
in the software for the MGCplus Setup Assistant (see TEDS operating manuel
"TEDS-module in transducer" on our website at ww.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.
Contents of the TEDS memory as defined in IEEE 1451.4
The information in the TEDS memory is organized into areas 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 4 areas:
Area 1:
An internationally unique TEDS identification number (cannot be changed).
Area 2:
The base area (basic TEDS) to the configuration defined in standard
IEEE1451.4. The transducer type, the manufacturer and the transducer serial
number are contained here.
