6.1.3 TEDS
The acronym TEDS stands for ”Transducer Electronic Data Sheet” and denotes a transducer
or sensor’s electronic data sheet which is saved to a small electronic chip or a corresponding
module and is intrinsically linked to the transducer.
In addition, valuable meta data is supplied, for example, calibration data providing essential
information for the traceability of measurements or tests. The electronic data sheet can be
located in the transducer housing, in the inseparable cable or connector plug.
The function and principle of operation are defined in Standard IEEE1451.4.

Data mode
Measurement mode
Transducer with TEDS module
e.g. U93
Transducer information stored in TEDS includes:
S
The physical unit of the measured quantity (N for force, for example) and its measuring
range
S
The unit of the electrical output signal (mV/V for bridge transducers, for example)
S
The linear characteristics as the relation between the measured quantity and the
electrical signal
S
If applicable, the transducer’s required excitation and electrical power supply
Additional information that can be read out using corresponding software, for example:
S
Transducer manufacturer, type, serial number etc.
S
Calibration date, recalibration interval, calibrator’s initials, etc.
Amplifiers of the QuantumX series enable transducer information stored in the electronic
data sheet to be read out and automatically implemented in the correct amplifier settings; this
allows fast and reliable measurement.
The electronic data sheet is automatically loaded, when the transducer is connected to the
device. Transducers are identified via the bridge between two pins in the connector. After the
digital identification mode, the amplifier automatically switches to the configured
measurement mode.
TEDS data can also be loaded via a software command, e.g. using catman
®
AP.
TEDS Editor enables all TEDS data to be read out and edited; see chapter 3.6.
