膜盒压力表适用于测量对铜合金不起腐蚀作用、无爆炸危险的微压和负压。气体广泛应用于锅炉通风和气体管道等设备上，本仪表可以就地安装并现场指示。
■主要技术指标
工作位置、环境：仪表垂直安装，工作环境温度－25～55℃相对湿度不大于80%,并且周围空气中不含有腐蚀仪表的有害气体。
温度影响：使用温度偏离20±5℃时，其温度附加误差不大于0、4%/10℃.

描述： |
为使通用型压力表能适用于测量腐蚀性强，高温，粘度大，易结晶，易凝固或者含有固态浮游物介质压力以及必须避免测量介质直接进入通用型压力表和防止沉淀物集聚且易清洗的场合，应必须采用隔膜压力表。隔膜压力表是由一个不同类型的通用压力表与一个具有特定要求的由连接体和隔膜隔离体组成的隔离器组成。通过这种配接，使一般通用型压力表，增加了隔膜压力在石油化工，制碱，化纤，染化，制药，食品和钢铁等行业生产过程中。测量流体介质压力时被广泛使用。
低压膜片表可以准确测量低压，一般来说压力不大于15psi |
