基于现场总线技术的智能差压变送器

INTELLIGENT DIFFERENTIAL PRESSURE TRANSMITTER BASED ON FIELD BUS TECHNOLOGY

运用现场总线技术改进单晶硅谐振式差压变送器 ,使其精度进一步提高 ,体积减小 ,使用更方便。

This paper introduces the signal crystal silicon resonant pressure transmitter accords with HART protocol. There are a microprocessor and a field bus interface in its. It has the features of itself management and two ports digital and imitation communication.
