型號(hào)描述
這種流量測(cè)量?jī)x適合具備高粘度的介質(zhì)，比如膠水、蜂蜜或機(jī)油。利用開(kāi)關(guān)輸出端，可直接控制閥門(mén)，由此在監(jiān)控系統(tǒng)內(nèi)部建立一個(gè)簡(jiǎn)單的兩點(diǎn)式調(diào)節(jié)回路?？芍苯釉陲@示屏上通過(guò)三個(gè)按鍵規(guī)定開(kāi)關(guān)點(diǎn)，或者也可選擇從外部通過(guò)一個(gè) 4-20 mA 標(biāo)準(zhǔn)信號(hào)輸入端規(guī)定開(kāi)關(guān)點(diǎn)。型號(hào) 8072 帶有可自由編程的開(kāi)關(guān)輸出端（晶體管或繼電器）、外部的額定值輸入端和/或 4-20 mA 工藝值輸出端。
1）在一臺(tái)儀器中進(jìn)行測(cè)量值顯示、監(jiān)控、傳輸及兩點(diǎn)式調(diào)節(jié)
2）可自由編程的開(kāi)關(guān)點(diǎn)（晶體管或繼電器）
3）通過(guò) TEACH-IN 自動(dòng)校準(zhǔn)
4）外部額定值規(guī)定和工藝值（在 4-20 mA 的范圍內(nèi)）
Type Description
This positive displacement flow sensor / switch with display is designed for use in slighly viscous fluid like glue, honey or oil and specially to switch a valve and to establish a monitoring system or an On/Off control loop. The switching points can be programmed with the 3-key keypad under the display or optionally from an external source over a 4-20 mA loop. The 8072 is proposed with On/Off output, or with external setpoints and/orprocess value outputs.
1）Indication, monitoring, transmitting and On/Off control in one device
2）Programmable outputs (transistor or relay)
3）Automatic-calibration: Teach-In
4）Communication - external setpoints and process value (4-20 mA)
