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 characteristics (electronic data sheet), trans
lates them into its own settings and measurement can then start.
The digital identification system is available at plug connection 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 mistake.
7.1
Hierarchy of user rights
7.1.1
Standard rights (USR level)
This level concerns rights which the user of the transducer 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 calibration laboratory, for
instance, if the sensitivity in the TEDS memory needs to be changed.
7.1.3
Administrator rights (ID level)
Administrator rights in relation to TEDS are intended for the sensor manufac
turer.
Different user rights are needed in order to amend the various entries in the
templates, and these rights may differ from one entry to the next within a tem
plate.
