压力变送器在光伏系统项目中有何作用？除了电力传输和电压转换，变压器还可以用作光伏系统中的电气隔离。隔离变压器的一次和二次是通过磁路传递能量，元件与电网电气隔离，可以防止DC分量和泄漏电流进入电网，适用于元件的负接地系统。工采网推荐一款压力变送器也可以用于光伏项目，压力变送器 － CS－PT1200，进口德国陶瓷芯体；数字式调校；多种连接器选择；多种压力接口选择；零位可任意迁移；可在50～100％间变量程；CE认证；符合RoHS标准。在实际使用差压变送器的过程中，经常考虑它的维护和安装。为便于操作，取压点与测量仪表之间会有水平差，或当被测介质有强腐蚀性、粘度过等限制因素时，会对整个压力测量过程造成一定障碍，甚至可能影响仪器的测量精度。因此，为了尽可能地实现差压变送器的   测量，通常采用差压变送器零点迁移技术。1 差压变送器零点迁移分类本质上讲，零点迁移共包括3种形式，分别是无迁移、正迁移和负迁移，其中正迁移和负迁移较为常见，以下则是对这两种迁移的介绍。1.1  正迁移变送器安装位置与测量液位水平度不同是实际测量中的普遍现象，如图1所示为一种迁移形式。根据观察，该容器为敞口容器，h为变送器安装位置与测量液位的水平度差，进而可以得到与压力差ΔP相关函数关系式ΔP=ρgH+ρgh。
