詳細(xì)介紹
Barksdale電子式壓力開關(guān)SW2000 Barksdale的SW2000電子式壓力開關(guān)擁有電子式開關(guān)的精度且價(jià)格經(jīng)濟(jì)。SW2000可提供兩種不同配置:二個(gè)開關(guān)量或一個(gè)開關(guān)量帶有 一個(gè)4-20 mA模擬量輸出。通過使用鍵盤和用戶友好的菜單界面 可以方便地進(jìn)行設(shè)定點(diǎn)和回差設(shè)定。模擬量輸出可縮放成從全量程的25%到100%。一個(gè)10-bit微處理器可自診斷并使開關(guān)時(shí)間延遲,壓力循環(huán)zui高次數(shù)可達(dá)每秒100次。開關(guān)擁有IP65標(biāo)準(zhǔn)防護(hù)等級(jí)并經(jīng)久耐用。對(duì)于需要較低的價(jià)格進(jìn)行精確壓力監(jiān)控的應(yīng)用,SW2000電子式壓力開關(guān)是一個(gè)*選擇。
特點(diǎn):
帶有內(nèi)部不銹鋼膜片的壓力控制器
高精度并且全量程可調(diào)節(jié)死區(qū)
二個(gè)固態(tài)觸點(diǎn)或一個(gè)固態(tài)觸點(diǎn)加一個(gè)4-20mA模擬量輸出
內(nèi)置數(shù)字壓力顯示
通過鍵盤可實(shí)現(xiàn)全部設(shè)定
適合于快速循環(huán)(每秒100次)
UL/CSA 認(rèn)證
