The iDRN-ST and iDRX-ST
signal conditioners provide
highly accurate, stable,
isolated measurement for
strain gage transducers
such as load cells,
torque transducers,
non-amplified pressure
transducers, and other bridge
based transducers. Both
models can accept signals
from 30 to 100 mV full scale
and provide 10 Vdc
reference voltage which
may be used for
transducer excitation.
