Description
HAWK 74L and 74B series bourdon tube all stainless steel pressure gauges are designed to fulfill the requirements of high quality from various industries at low cost condition. The 316SS construction pressure gauges are good in use on demanding applications where corrosion resistance, rugged environment resistance and reliable operation are required. Liquid Filling or dampened movement is available to diminish dampened movement is available to diminish and further enhances the gauge life. The socket of it is welded to the case, the gauge is stronger, more durable, and shockproof. This design also can eliminate the leak paths when the gauge is liquid filled and extend its service life .
Typical Applications
- Petrochemical and chemical processing
- Medical and pharmaceutical industry
- Industrial OEM equipment
- Hydraulic monitoring systems
- Power generating stations
- Offshore oil platforms
- Pneumatic systems
- Level measurement
Specifications
Operating
Steady: 75%*full scale value
Pulsation: 50%*full scale value
Sudden: 100%*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 15,000 PSI including compound range.
Temperature limit
Ambient:
– 40 to 80°C (Dry Gauge)
