BURKERT通用調(diào)節(jié)器177091具有緊湊型的結(jié)構(gòu)方式，非常適合同樣采用緊湊型設(shè)計(jì)的調(diào)節(jié)系統(tǒng)。這種調(diào)節(jié)器經(jīng)測試可兼容與所有 Bürkert 比例閥和傳感器，在使用標(biāo)準(zhǔn)信號（4-20 mA、0-10 V 或 PWM 輸出信號）的前提下，可以與各種非 Bürkert 調(diào)節(jié)閥相組合。這種具有 PI 特性的過程調(diào)節(jié)閥，配備了大量的附加功能。通過 3 個模擬輸入端，可以將工藝實(shí)際值作為標(biāo)準(zhǔn)信號 (4-20mA / 0-10V)、電阻信號 (PT100) 或頻率信號讀入。通過電流或電壓標(biāo)準(zhǔn)信號或者鍵盤，可以規(guī)定工藝額定值。特別適合溫度調(diào)節(jié)任務(wù)，可以設(shè)計(jì)其下方安裝有流量調(diào)節(jié)裝置的級聯(lián)式結(jié)構(gòu)。通過控制比例閥和過程閥，可以在流體技術(shù)領(lǐng)域中完成各種各樣的調(diào)節(jié)任務(wù)，也可將其應(yīng)用于液態(tài)的或氣態(tài)的介質(zhì)。
