差動(dòng)遠(yuǎn)傳壓力表YTT
Ressure Gauge with differential transmitter
產(chǎn)品簡介
差動(dòng)遠(yuǎn)傳壓力表既可對所測壓力做現(xiàn)場指示又能轉(zhuǎn)換為0—10mA或4—20mA的標(biāo)準(zhǔn)電流信號輸出?？梢耘cⅡ型或Ⅲ型電動(dòng)單元組合儀表中的二次儀表、調(diào)節(jié)器、計(jì)算單元及巡回檢測裝置組成自動(dòng)記錄、調(diào)節(jié)、控制等系統(tǒng)。按輸入電壓及輸出電信號的不同分為3 種型號：831 （220V AC 50Hz 0 — 10mA）、832 （24V DC 4 — 20mA）、833（220V AC 50Hz 4 — 20mA）。
儀表適用于石油、化工、冶金、電路、輕工業(yè)等行業(yè)測量對銅合金無腐蝕作用的氣體及液體的壓力。與此類隔離器連接后，可在各種腐蝕性的環(huán)境中使用。
PRODUCT OVERVIEW
8.30 series Pressure Gauge with differential transmitter is not only able to indicate thepressure value, but also transform it into 0-10mA or 4-20mA, the standard current output
signals, with the secondary meter, regular, calculating unit and cyclic detector, the gaugeswill become an system with automatic record, regulate and control.
It is used in petrochemical, metallurgy, electronic and light industry, suitable for the gaseous or liquid medium that will not corrode the copper alloy and iron. Connected with insulations, it could be used in corrosion environments.
