Technical content
- Designed to isolate the pressure measuring instrument from corrosive or viscous process media
- Utilize an all welded, all metallic housing design to eliminate potential leak paths
- For use with gauges with dial sizes of 2-1/2" and smaller, and pressure ranges no less than 100 psig
- Housing and diaphragm offered in a variety of materials to suit most applications
- A flushing port is available to clean wetted areas and prevent process media build up
- Consider instrument size, pressure range, media composition, ambient and operating temperature, and maximum working pressure when selecting
- Capillaries and cooling elements are available for elevated process temperatures, see page 24
- Fill fluid must be compatible with process media; i.e. Glycerin may become volatile in conjunction with a strong oxidizing agent such as chlorine, forms of oxygen or peroxide and nitric acids Non-Replaceable Diaphragm Standard & Elevated Pressure TYPE 25/25H25/25H Water and wastewater Oil and gas Petrochemical Chemical processing Industrial automation Marine Agriculture Steel fabrication Mud pumping Pulp and paper Pneumatic
