FMA-A2107_FMA-A2108_FMA-A2109_FMA-A2120質(zhì)量流量計(jì)和控制器OMEGA

FMA-A2000系列電子質(zhì)量流量計(jì)／控制器性能出眾、 功能多樣、設(shè)計(jì)先進(jìn)、外形緊湊。FMA-A2000利用毛細(xì)管式熱感技術(shù)直接測量氣體的質(zhì)量流量。無需進(jìn)行溫度、壓力或平方根校正。FMA-A2300／2400系列配備LCD顯示屏，并且所有型號(hào)都提供線性0 ~ 5 Vdc和 4 ~ 20 mA輸出。

FMA-A2000測量0 ~ 100 SLM之間24個(gè)量程的氣體質(zhì) 量流量。要查看完整列表，請參閱下***頁的量程表。 FMA-A2000系列與大部分非腐蝕性氣體相容。建議用戶對照氣體相容性檢查接液材料。
