测压元件

This technique is to make a device to instead those transmitters and reduce the need in pressure gauges. Using the electronic valve and flexible tube to construct the control panel is effective to connect the single pressure gauge with every sensor point in ventilation duct.

利用软管将欲量测之管段的压力导引到控制箱内，并将所有导引来的静压分别安装在一组并联的各电磁阀上，再将所有的动压分别安装在另一组并联的各电磁阀上，而该两组并联电磁阀的底部各安装一根连通管连结至单一差压计的高低压两端，并利用控制元件切换各电磁阀的启闭以达到多点压力监测切换的目的。
