Diaphragm Seals

DIAPHRAGM SEALS Available in various materials of construction for transmitters and gauges in every kind of service.

DIAPHRAGM SEALS

• Designed to isolate the pressure measuring instrument from corrosive or viscous process media
• Metallic and non-metallic materials available
• Consider gauge size, pressure range, media composition, ambient and operating temperature, and maximum working pressure when selecting
• For process temperature over 212°F, a capillary is recommended
• Fill Fluid must be compatible with process media; i.e. Glycerine may become volatile in conjunction with a strong oxidizing agent such as chlorine, forms of oxygen or peroxide and nitric acids
