溫度傳感器在立式彎管機上有什么用？

   立式彎管機控制系統中，CPU將給(gei)(gei)定(ding)的控制量通(tong)過模(mo)擬量模(mo)塊，輸出(chu)到電(dian)壓(ya)變送器，電(dian)壓(ya)變送器將給(gei)(gei)定(ding)值輸入到中頻控制板上，中頻控制板根據給(gei)(gei)定(ding)電(dian)壓(ya)，進行工(gong)作(zuo)。 立式彎管機的控制系統有什么特(te)色？

溫度(du)傳(chuan)感(gan)器(qi)，電(dian)(dian)(dian)(dian)(dian)壓變送器(qi)、電(dian)(dian)(dian)(dian)(dian)流變送器(qi)和光電(dian)(dian)(dian)(dian)(dian)編碼器(qi)將實時采集(ji)的(de)數據，通(tong)過模擬量模塊傳(chuan)送給CPU的(de)高速計(ji)數器(qi)與給定量進行比(bi)較，從而達到PLC對溫度(du)和速度(du)的(de)閉環控制(zhi)。電(dian)(dian)(dian)(dian)(dian)氣原(yuan)理包(bao)括(kuo)控制(zhi)電(dian)(dian)(dian)(dian)(dian)路和主(zhu)電(dian)(dian)(dian)(dian)(dian)路，控制(zhi)電(dian)(dian)(dian)(dian)(dian)路包(bao)括(kuo)PLC的(de)I/O外圍接線，自動控制(zhi)、手(shou)動控制(zhi)等電(dian)(dian)(dian)(dian)(dian)路。抗干擾(rao)措施：PLC輸出點帶感(gan)性負載(zai)時，負載(zai)斷電(dian)(dian)(dian)(dian)(dian)時。硬件設(she)計(ji)的(de)主(zhu)要內容是電(dian)(dian)(dian)(dian)(dian)氣控制(zhi)系(xi)統的(de)設(she)計(ji)，抗干擾(rao)措施設(she)計(ji)，電(dian)(dian)(dian)(dian)(dian)氣控制(zhi)元件的(de)選擇。

電氣元器件選擇：是控制要求所需的按鈕、開關、傳感器、保護電器、接觸器、指示燈和電磁閥等。會對PLC輸出點產生浪涌電流并沖擊PLC，直流感性負載應并聯續流二極管，對交流感性負載并聯流涌吸收電路，有效保護PLC控制器。
