3.5 TEDS-transducers (electronic data sheet)

3.5.1 TEDS connection

TEDS stands for "Transducer Electronic Data Sheet". Transducers with elec-
tronic data sheets as per standard IEEE 1451.4 can be connected to the
MP85A process controller. This enables the automatic setting of the meas-
uring amplifier: The transducer characteristics (electronic data sheet) are read
and translated into own settings and measurement can then start. A six-wire
configuration must be used for TEDS to be connected.

3.5.2 Parameterization with TEDS

If a transducer with TEDS, containing the parameterization data for a sensor,
is connected, this can be used to parameterize the MP85A process controller
automatically.
When the MP85A process controller is activated, it automatically detects
whether a TEDS is connected. When the transducer is replaced in the activ-
ated state, the new TEDS is also detected automatically.
NOTE
To monitor TEDS functionality and to protect scaling from manual inter-
vention, check the boxes in the TEDS dialog box in the PME Assistant
(menu: TEDS). TEDS functions can be enabled individually for each
channel. Using TEDS for piezoelectric measurement chains is described
in Section 3.4.4 .
