【 摘 要 】

In this paper a novel HART transmitter architecture is presented, based on a high accuracy 4-20 mA transmitter. Its main purpose is to develop a transmitter with a digital communication protocol without negatively affecting the 4-20 mA transmitter performance. It was used in this work a high accuracy pressure transmitter (error of less than 0.1% F.S.) that requires the use of digital signal processing for the compensation and calibration process. This circuit uses a digital sensor signal processor (DSSP) and the digital communication capacity in order to acquire the needed data to meet the HART standard requirements.
