各位大佬，最近有人要我做個(gè)恒壓供水，我在捉摸著(zhù)怎么報價(jià)�，F在有幾種方式  1、是變頻器直接接壓力傳感器     2、plc+變頻器+觸摸屏  3、恒壓供水控制器（淘寶購買(mǎi)）+變頻器
   這幾種方式價(jià)格坑定差距比較大。我想請教下 這幾種方式具體差異到底在哪里啊  ，哪位熱心大佬能否幫解答一下

一用恒壓變頻供水控制器+變頻器+遠程壓力表,設置簡(jiǎn)單,
二;變頻器直接加供水繼電器擴展板+遠程壓力表也行,只是設置麻煩點(diǎn);
三;PLC+變送器+變頻器+元程壓力表,成本要高很多,除非是大型的場(chǎng)所,恒壓變頻供水控制器是最佳選擇.
