Transducer connection
SG transducers with full bridge can be connected.
Bridge resistance R

= 40...4000
Ω
(external excitation voltage). SG transducers must
operate at a bridge excitation voltage of 5 V
DC
.
Transducers with a bridge resistance >1000
Ω
can also be connected in principle. How
ever, this will increase the noise of the measurement signal (increased measurement
ripple).

Important
Make sure that a low-noise constant voltage source is used for the excitation voltage, as
the quality of the power supply is directly reflected in the measurement result (see Calcula
tion).
