Teds Transducer Identification - HBM PACEline CMC Bedienungsanleitung

18
The supply voltage and the RANGE1 / RANGE2 and MEASURE / RESET
control inputs are electrically isolated from the measurement circuit.
NOTE
Piezoelectric force transducers and charge amplifiers are
calibrated jointly as a measuring chain at the factory. They
make up a single unit, which is marked by an identical
production number on the force transducer and on the charge
amplifier. The data stored in TEDS are only valid for the
particular two‐part measuring chain (see Section 6.3).
ATTENTION
If either the force transducer or the charge amplifier are
replaced, calibration is no longer valid. Incorrect measured
values could be displayed and/or forwarded to downstream
evaluating electronics.
Two through‐holes (Ø 4 mm) are provided for screw‐mounting the charge am­
plifier.

6.2 TEDS transducer identification

TEDS stands for "Transducer Electronic Data Sheet". An electronic data sheet
per the IEEE 1451.4 standard is stored in the charge transducer of the
piezoelectric measurement chain, making it possible for the downstream
evaluating electronics to be set up automatically. The suitably equipped
evaluating electronics import the measuring chain characteristics (electronic
data sheet), translate them into its own settings and measurement can start.
Switching from Range1 to Range 2 automatically makes the valid TEDS
information available as well.
TEDS then has to be re‐imported by the downstream evaluating electronics.
A digital identification system is available at PIN 4 (to ground). The basis for
this is a DS2433 1‐wire EEPROM, made by Maxim/Dallas.
