Signals & Electrical
Millivolt signal
A very small analogue voltage, often produced directly by a sensing element.
IN ONE SENTENCE
Some sensors output only a few thousandths of a volt and need careful amplification.
In normal English
Load cells, strain gauges and some pressure transducers can produce small mV signals. Because the signal is tiny, cable noise and grounding matter much more.
Why would I use it?
Use it when working directly with bridge sensors, load cells or specialist transducers.
THINK OF IT LIKE…
A whisper that needs an amplifier before the rest of the system can hear it.
