True or False: Smart transmitters can only transmit process information in digital format.

Smart transmitters are designed to transmit process information in both digital and analog formats. This flexibility allows them to communicate effectively with various control systems, accommodating different integration needs within industrial applications. While smart transmitters have advanced digital capabilities that enhance their functionality—such as self-diagnostics, calibration, and greater accuracy—they are still equipped to transmit data in analog formats like 4-20 mA signals for compatibility with older systems. Therefore, stating that they can only transmit information in digital format is not accurate. This is why the answer is considered to be true.
