7 TEDS transducer identification
(Option 3, Code PNJ)
TEDS stands for "Transducer Electronic Data Sheet". An
electronic data sheet can be stored in the transducer as
defined in the IEEE1451.4 standard, making it possible
for the amplifier to be set up automatically. A suitably
equipped amplifier reads out the transducer characteris
tics (electronic data sheet), translates them into its own
settings and measurement can then start.
The digital identification system is available at plug con
nection PIN 7 to PIN 2. The HBM TEDS Editor is used to
store the data. This is a component of the HBM
"MGCplus Setup Assistant" software. You can use the
Editor to manage different user rights, thus protecting the
essential transducer data from being overwritten by mis
take.
7.1 Hierarchy of user rights
7.1.1 Standard rights (USR level)
This level concerns rights which the user of the trans
ducer needs in order to change the entries which depend
on the conditions of use.
7.1.2 Calibration rights (CAL level)
This level concerns rights which are needed by a calibra
tion laboratory, for instance, if the sensitivity in the TEDS
memory needs to be changed.
