Description
HAWK type 16L and 16B solid front process gauges with Aluminum case are widely used for petrochemical and chemical processing industries. There is a solid wall between pressure sensing element and the window. This design provides better safety for monitoring the gauges in the event of the gauge failure. The gauge is available in bottom or lower back connection. This type feature a filling vent. This special design lets users quick and convenient to fill dry gauges without any special tools or fixtures.
Typical Applications
- Petrochemical and chemical processing
- Offshore oil platforms
- Industrial OEM equipment
- Power generating stations
- Compressors
- Pneumatic systems
- Pump applications
- Food processing plants
- Refrigeration and HVAC systems
- Construction and agriculture equipment
- Energy and water treatment plants
Specifications
Operating
Steady: 100%*full scale value
Pulsation: 90%*full scale value
Sudden: 130%*full scale value
The appropriate operating range falls in the middle half of the gauge (25%to 75% of full scale). If you choose the unsuitable range, the fatigue of bourdon tube may be resulted. HAWK Supplies a wide selection of range from vacuum to 20,000 PSI including compound range.
