隔膜压力表的描述

隔膜压力表更适用于低压范围。通过圆形波纹隔膜元件的大型工作表面，可以可靠地测量小压力范围。

432.50型隔膜压力表符合EN 837-3标准。高质量的设计特别适用于化学和石化工业、石油和天然气工业以及动力工程。

不锈钢表壳和接液部件可满足对抗侵蚀性价值的高要求。对于特别高的阻力要求，该隔膜压力表的压力腔体可以选择使用各种特殊材料（如PTFE、钽或哈氏合金）进行设计。

对于高粘度、结晶或受污染介质的测量，建议使用敞开式连接法兰。敞开式连接法兰相较于螺纹连接，优点在于不会堵塞压力口。通过敞开式连接法兰上的附加冲洗连接，可轻松清洁压力腔体。

带有隔膜元件的测量系统，基于隔膜可以将其自身支撑在上法兰上的设计理念，能够提供良好的过压保护。作为标准，432.50型隔膜压力表可达到满量程值5倍的过载安全。作为可选项，可以实现更高的过载安全性。
