D212 D214壓力鈍感質(zhì)量流量計(jì)
簡要描述：概要高穩(wěn)定性的質(zhì)量流量計(jì)－氣體流量控制不受上流和下流端壓力變化的影響
產(chǎn)品型號：- 廠商性質(zhì)：經(jīng)銷商
- 更新時(shí)間：2025-03-18
- 訪 問 量：1266
概要
高穩(wěn)定性的質(zhì)量流量計(jì)－氣體流量控制不受上流和下流端壓力變化的影響。不同壓力感測，采用壓力鈍感模式
特征
- 采用不同壓力感測即鈍感模式
- 縮小氣體柜的體積（不再需要壓力傳感器，調(diào)壓閥和過濾器）
- 流量控制量程范圍廠
- 精度高
- 提高產(chǎn)能－可以提供標(biāo)準(zhǔn)流量給半導(dǎo)體制程。
