Abstract

本发明提供一种差压变送器零点调整的方法，关闭低压侧进口阀门，打开平衡阀，这样就可以达到高低压侧平衡，阀门的调整可通过调零螺丝或手操器对变送器零点校正，不需要排泄；其优点是只需要操作两个阀门，就可对变送器进行零点校正，既节省了时间，又不需要排泄，能够及时将变送器投入工作状态，提高效率。

Description

一种差压变送器零点调整的方法
技术领域
本发明涉及一种调整方法，具体涉及一种差压变送器零点调整的方法。
背景技术
目前传统的差压变送器调零点，需要关闭高低压进口阀门、打开平衡阀、打开高低压侧排泄孔，方可进行零点调整。这样不仅操作麻烦、而且如果介质是液体，尤其是微差压变送器，排泄不净，容易造成零点漂移，致使测量结果不准确，调整完毕后需要将上述操作的阀门全部复位，并且需要较长时间才能达到工作状态(排放的冷凝液需重新冷凝)。
发明内容
为解决现有技术的不足，本发明提供一种差压变送器零点调整的方法。
本发明所采取的技术方案是：一种差压变送器零点调整的方法，关闭低压侧进口阀门，打开平衡阀，这样就可以达到高低压侧平衡，阀门的调整可通过调零螺丝或手操器对变送器零点校正，不需要排泄。
本发明的有益效果是：只需要操作两个阀门，就可对变送器进行零点校正，既节省了时间，又不需要排泄，能够及时将变送器投入工作状态，提高效率。
具体实施方式
一种差压变送器零点调整的方法，关闭低压侧进口阀门，打开平衡阀，这样就可以达到高低压侧平衡，阀门的调整可通过调零螺丝或手操器对变送器零点校正，不需要排泄。
