Transmitters that have built-in microprocessors are referred to as what?

Transmitters equipped with built-in microprocessors are classified as smart transmitters. This designation highlights their advanced functionalities compared to traditional transmitters. Smart transmitters can perform a variety of tasks, such as self-diagnostics, advanced signal processing, and communication with other devices or systems, enabling them to provide more accurate and reliable measurements.

The integration of microprocessors allows smart transmitters to have enhanced features, including digital output capabilities, the ability to store calibration data, and support for protocols that allow for easy integration into complex automation systems. These features significantly improve efficiency and reduce maintenance requirements.

In contrast, while analog transmitters rely on simpler technologies and typically provide continuous output in analog format, and digital transmitters may offer output in digital format, they do not possess the comprehensive capabilities of smart transmitters. Simple transmitters generally refer to basic devices with limited functionality, lacking the sophisticated features found in smart transmitters. Therefore, the classification of transmitters with embedded microprocessors as "smart" accurately reflects their innovative attributes and operational capabilities.
