Transducer Excitation

Last Modified: April 19, 2018

Signal conditioning systems can generate excitation for some transducers. Strain gages and RTDs require external voltage and current, respectively, to excite their circuitry into measuring physical phenomena. This type of excitation is similar to the power a radio needs to receive and decode audio signals. Several measurement devices provide the necessary excitation for transducers. Consult your device documentation to see if your device can generate excitation.
