Retrofitting the transducer plug with TEDS
The IEEE standard 1451.4 defines a generally accepted process which enables sensors to
be identified. The sensor is identified via the respective data sheet which is stored in
electronic format in the sensor, cable or plug on a 1−wire EEPROM (TEDS − Transducer
Electronic Data Sheet). The amplifier uses a serial 1−wire interface for communication with
this EEPROM, reads out the data sheet and configures the amplifier accordingly.
Retrofilling TEDS in the plug is shown in the figure below.
HBM empfiehlt den TEDS-Baustein (1-Wire
R EEPROM) DS24B33 von Dallas Maxim. Um
diesen Chip lesen und beschreiben zu können ist mindestens Firmware-Version 1.21.16 /
2.21.16 sowie mindestens TEDS-Editor Version 3.3 nötig.
