Description
HAWK 25L and 25B series bourdon tube all stainless steel pressure gauges are designed to fulfill the requirements of high quality from various industries. The wetted parts can be in brass or 316 stainless steel l. The 316SS construction pressure gauges are good in use on demanding applications where corrosion resistance, rugged environment resistance and reliable operation are required. 1 1/2″, 2″ and 2 1/2″ smaller size gauges are used whenever space limitations exist. The all SS construction of these gauges are ideal to use in harsh environments.
Typical Applications
- Petrochemical and chemical processing
- Medical and pharmaceutical industry
- Industrial OEM equipment
- Hydraulic monitoring systems
- Power generating stations
- Pumps and Valves
- Pneumatic systems
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 20,000 PSI including compound range.
