Smart transmitters are microprocessor-based transmitters that can perform calculations, produce diagnostics.
They are useful in remote area communication and calibration process. The sensor signal transmitter into a unified standard signal: 0/4-20mADC, 1-5VDC, 0-10VDc. The output control signal is standard such as 4-20mA.
A smart sensor is insensitive to noise and which use the digital communication protocol that can be used for reading transmitter measurement and configure various settings in the transmitter.
