德國(guó)Sartorius PR1590模擬信號(hào)變送器可以對(duì)電流、電壓等電量參數(shù)或溫度、電阻等非電量參數(shù),進(jìn)行高速精確測(cè)量,經(jīng)隔離轉(zhuǎn)換成標(biāo)準(zhǔn)的模擬信號(hào)輸出。既可直接與指針表,數(shù)顯表相接,也可以與自控儀表(如PLC)、各種A/D轉(zhuǎn)換器、以及計(jì)算機(jī)系統(tǒng)配接。
The analogue transmitters of the PR 1590 series from Sartorius have been especially designed for use in industrial environment, and are particularly suited for applications with hazardous areas (zone 1) like chemical, petrochemical and food industries. The applications range from level control and simple weighing to complex applications e.g. mixing and filling stations, in conjunction with PLCs, computers or other supervisory systems.
