our public
listing to determine whether your Organization
has already been issued a Manufacturer ID assignment.
If your Organization has already been issued
an assignment, please email
us to obtain contact information for the
Administrator of the assignment. If a new assignment
is required, a Usage
Percentage Letter must be submitted.
The IEEE does not accept requests for applicant-specified
identifiers.
Within the 64-bit section of the 1451.4 TEDS,
called basic TEDS, the manufacturer of the transducer
is defined with a 14-bit code called the manufacturer
ID. The IEEE Registration Authority issues the
manufacturer ID, to guarantee that it is unique
to a manufacturer, and publishes the list of existing
IEEE 1451.4 manufacturer ID's. Data acquisition
systems may make use of the basic TEDS, including
manufacturer ID, in determining the transducer
type and the proper template to be used in unpacking
TEDS data. Every manufacturer of IEEE 1451.4 compliant
transducers is required to use a unique IEEE 1451.4
manufacturer ID (see IEEE Std 1451.4.2004 subclause
5.1.1, Table 2).
The IEEE Registration Authority will assign an
additional manufacturer ID to any organization
requesting one, providing they submit an affidavit
on company letterhead to the IEEE Registration
Authority c/o IEEE Standards Department, stating
that their company will not "ship" product
in the new manufacturer ID assignment until well
after they have reached (shipped) at least 95%
of the numbering capacity of the original manufacturer
ID. The pool of individual transducer model numbers
available to each holder of a single 14-bit manufacturer
ID, using 50 bits of the 64-bit basic TEDS as
defined in IEEE Standard 1451.4-2004, is in excess
of 54.5 million models. Each model number may
be produced up to a total in excess of 16.7 million
serialized copies. The number of serialized copies
of a model number may be increased by using additional
version numbers, as defined by the Standard. A
single manufacturer ID, within the structure of
the IEEE 1451.4 Basic TEDS, may be used to identify
in excess of 9 x 1014 individual transducers.
