4-20mA signal conditioners
Browse by category
Our portfolio of 4-20mA current transmitters offers a perfect balance of integration and simplicity to facilitate industry standard 4-20 mA loop designs. Varying levels of integration provide optimal design flexibility while still offering useful features like sensor linearization, sensor excitation sources, SPI communication, diagnostics, and protection features. These devices are available in tiny packages, as small as 3 x 3 mm, for maximum space savings with optimal power dissipation.
