Remote Sensors
Remote Sensing
All sensors in a high noise environment should be
considered as remote sensors. Also, sensors not located
on the same PCB as the signal conditioning circuitry
are remote. Remote sensing applications typically use a
differential amplifier or an instrumentation amplifier.
