Using batteries is one technique for developing circuits that are isolated. Designing "Galvanic Isolation" into your products is just as effective. Dataforth's signal conditioners are designed with full 3-way isolation - the signal path, the field circuit power supply and the system circuit power supply are each isolated!
Matter of fact, using Dataforth's isolated signal conditioners are an excellent way to measure batteries! Many customers use Dataforth's isolated signal conditioning modules, SCMs, to measure batteries cell-to-cell and rely on the inherent high common mode rejection to protect sensitive monitoring and control devices. Moreover, Dataforth's SCM5B40 family
provides 200 megohm input resistance in addition to a 160dB common mode rejection ratio!SCM5B Family
If you use them or are involved in battery or fuel cell design, or manufacture, Dataforth has a signal conditioner that can protect, amplify (or attenuate), isolate and filter your valuable measurement and control data!
