Dwyer产品 43000系列Capsu-Photohelic®液用差压表/开关美国德威尔压差表流量计差压计差压开关差压变送器

43000系列Capsu-Photohelic®液用差压表/开关
43000系列Capsu-Photohelic®液用差压表/开关组合了多功能，高重复性的开关和高精度的差压表，差压表采用了我们可靠耐用的Magnehelic差压表的设计理念。Capsu-Photohelic®液用差压表/开关采用膜盒传感器，能够监测液体和气体的压力到500 psig(34bar)。可选铸铜材质用于水或水基液体。带有两个光电感应的双刀双掷开关用于高/低限位控制。直接通过面板上的旋钮就很方便的改变设定点。每个单独设定点的回差小于满刻度的1% ，两个设定点可以交互成为一个可调节的盲区，适用于水泵控制等应用场合。
