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.
HBM provides you with the TEDS Editor for storing your data. This is included
in the software for the MGCplus Setup Assistant.
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 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 num
ber are contained here.
Area 3:
If applicable, data specified by the manufacturer are contained in this area:
These specify
S the transducer type,
S the measured quantity,
