CMD
7.16 Content of the TEDS module as
defined in IEEE 1451.4
The information in the TEDS module is organized into
areas, which are prestructured to store defined groups of
data in table form. Only the entered values are stored in
the TEDS memory itself. The evaluating electronics
assign the interpretation of the respective numerical val
ues. This places a very low demand on the TEDS mem
ory. The memory content is divided into three areas:
Area 1:
An internationally unique TEDS identification number
(cannot be changed).
Area 2:
The base area (basic TEDS) with a configuration defined
in standard IEEE 1451.4. The transducer type, the manu
facturer and the transducer serial number are contained
here.
Area 3:
Data specified by the manufacturer and the user are con
tained in this area. This includes:
- the transducer type,
- the measurand,
- the electrical output signal,
- the required excitation.
As an example, the "Value" column in the tables below
contains typical values for a CFT force transducer with
20 kN (a manufacturing certificate is included with the
transducer) and a CMD with the serial number 123456,
