XDR – Transducer measurements
Measurement data from transducers that measure physical quantities such as temperature,
force, pressure, frequency, angular or linear displacement, etc. Data from a variable number
of transducers measuring the same or different quantities can be mixed in the same
sentence.
This sentence is designed for use by integrated systems as well as transducers that may be
connected in a "chain" where each transducer receives the sentence as an input and adds
on its own data fields before retransmitting the sentence.

Data, variable number of transducers
Transducer No. 1 ID
Units of measure, transducer No. 1

Measurement data, transducer No. 1
Transducer type, transducer No. 1 (see
Note 2)
NOTE 1
Sets of the four fields "type-data-units-ID" are allowed for an undefined
number of transducers. Up to "n"transducers may be included within the
limits of allowed sentence length; null fields are not required except where
portions of the "type-data-units-ID" combination are not available.
NOTE 2
Allowed transducer types and their units of measure are as specified in
below table – see next page.
