Transmitters with built-in microprocessors are referred to as what?

Transmitters with built-in microprocessors are called smart transmitters. These devices utilize microprocessor technology to provide enhanced functionality compared to traditional transmitters. A smart transmitter can perform various tasks that integrate data processing, such as compensation for temperature or pressure variations, diagnostics, linearization of the sensor output, and communication over digital protocols. This added intelligence allows for improved accuracy and reliability in measurement and control systems.

Smart transmitters can also be configured and calibrated in the field, allowing for easier maintenance and increased flexibility. Their ability to collect and process data directly at the source helps reduce errors and improves the overall efficiency of the system they are part of.
