Industry Standard Architecture
a type of signal conditioning in which you isolate the transducer signals
from the computer for safety purposes. This protects you and your
computer from large voltage spikes and makes sure the measurements from
the DAQ device are not affected by differences in ground potentials.
the voltage that an isolated circuit can normally withstand, usually
specified from input to input and/or from any input to the amplifier output,
or to the computer bus
constructed to maintain constant temperature across area. Isothermal
construction of terminal blocks increases thermocouple measurement
accuracy.
