基于HART协议智能压力变送器的检定方法研究

Research on the Calibration Method of Intelligent Pressure Transmitters Based on the HART Protocol

与常规压力变送器相比,智能压力变送器的功能和性能更具有优势。本文基于HART协议的智能压力变送器,提出采用一套压力控制器对其进行检定。实验证明:通过使用一套压力控制器和上位机软件,对其进行自动调整和检定,能对检测点的数据进行自动计算,大幅度提升了检定效率。

Compared with conventional pressure transmitters,intelligent pressure transmitters have more advantages in function and performance.In this paper,the intelligent pressure transmitter based on HART protocol is verified by a set of pressure controller.The experiment shows that by using a set of pressure controller and host computer soft-ware,it can automatically adjust and verify the data of the detection point,and greatly improve the verification effi-ciency.
