Many common sensors require power to generate a signal. These include strain gauges and RTDs. How to provide external voltage or current excitation signals?
Signal conditioning products also provide excitation for some transducers. For example:strain gauges, thermistors and RTDs, require external voltage or current excitation signals.
Transducer excitation provides this power so sensors do not require external power sources.
