5.5 Transducer
Two transducers can be connected to screw terminals 5 and 6, independently
of one another. The two measurement channels are parameterized using the
PME Assistant (“Transducer” menu).
5.5.1 Synchronization of carrier frequencies
Synchronization prevents interference occurring due to minor differences
between the carrier frequencies of several amplifiers, i.e. mutual interference
between amplifiers.
Synchronization is advisable for transducers with carrier frequency excitation
when
S The transducer cables of several devices run side by side,
S The measuring points are unshielded and close together.
Even if you are not using a CAN bus, always use the ribbon cable for
synchronization between devices, see section 4.2 on page 20.
Important
To synchronize several devices, specify one device as the master and set all
other devices as slaves. Perform settings via the PME Assistant program
(Basic settings -> “Hardware synchronization” menu).
5.5.2 Strain gage and displacement transducers, potentiometric and
LVDT sensors
In carrier-frequency amplifier mode, you can connect the transducer models
shown in Fig. 5.4, page 28.
