1950-1-2F DWYER 板卡船舶半导体工控备件优势经销

1950-1-2F 是美国 ‌Dwyer‌ 公司生产的一款‌防爆型微差压开关‌，主要用于工业环境中对空气或其他兼容气体的压差进行监测与控制。该设备具备防爆设计，适用于可能存在易燃易爆气体的危险场所，如化工厂、石油平台、船舶机舱等。

‌型号‌：1950-1-2F

‌品牌‌：Dwyer（美国压力与流量测量仪器制造商）

‌功能类型‌：防爆差压开关

‌测量范围‌：0.4–1.6 in.w.c.（英寸水柱），适用于低压力差检测场景

‌输出方式‌：继电器输出，支持现场设定，可调节动作点与死区

‌防爆认证‌：通过 FM、UL、CSA、CE 等多项国际安全认证，适用于 Class I, Division 1 等危险区域

‌防护等级‌：具备防水防爆结构设计，可在恶劣工业环境中稳定运行

‌安装方式‌：标准导轨安装（DIN Rail），便于集成于控制柜中

‌通风与空调系统‌：用于监测过滤器压差，判断堵塞状态，实现自动报警或联动清洗

‌洁净室与实验室‌：监控房间正压状态，确保洁净环境不被污染

‌工业安全系统‌：在燃气锅炉、燃烧设备中用于风压监测，防止回火或熄火事故

‌船舶与海上平台‌：用于机舱通风监控、防爆区域压力控制，符合船级社安装标准

仅适用于空气或相容气体，禁止用于可燃气体作为传感介质

高压端口连接时需避免将爆炸性气体引入低压侧，防止内部电弧引发危险

若用于正压控制系统，建议将低压口通向非危险区域，确保安全隔离

定期校验设定点与响应时间，确保在关键安全链路中可靠动作
