HART协议在压力计量中的研究与应用

Research and Application of HART Protocol in Pressure Measurement

以上海盛泰克和中科博微的压力表为例,详细解析了厂家附带的上位机软件与压力表头之间的HART协议交换过程,从通用命令、常用命令和专有命令3方面介绍了压力表实时数值读取、标定校准、电流标定、量程设置、量程迁移等操作过程。通过HART协议读写操作,可以实现压力送检设备的自动化计量,有益于提高压力仪表检定/校准的工作效率以及操作准确度,简化了计量工作流程,降低了工作强度。

Examples in Shanghai sheng tek and bowei micro pressure gauge, parsing the manufacturer with PC software and HART protocol exchange process between pressure meter. From general command, commonly used commands and proprietary command three aspects introduced the real-time numerical pressure gauge reads, calibration, current calibration, range Settings, such as range migration process. Through the reading and writing operation of HART agreement, the automatic metering of pressure inspection equipment can be realized, which is beneficial to improve the work efficiency and operation accuracy of pressure instrument verification/calibration, simplify the work flow of metering and reduce the work intensity.
