Measurement Application Tech Notes
Measurement
using microprocessor based A-D signal conditioners, or measurement
using instrumentation amplifier based
signal conditioners; what's the difference?
Isolation amplifiers, & data converters integrate into problem specific application solutions.
In applications where higher voltages than
an A-D can read need to be monitored, the ROI-ISOV10 can be used to couple a voltage divider; using an isolation amplifier, to monitor high voltage with the 5V voltage A-D.
Live
zero is a key advantage of 4-20mA instrumentation signals.
When
setting up a measurement system using A-D's with signal conditioners, with
multiple signal types to choose from; what's the difference?
Temperature
sensors, temperature transmitters, & data converters integrate into
problem specific application solutions.
4-20mA
transmitters allow resistive sensor measurements to be extended long
distances.
Simple
wiring is a key advantage of 4-20mA loop transmitters.
