Description

HAWK 27L and 27B series bourdon tube all stainless steel pressure gauges are designed to fulfill the requirements of high quality from various industries. Because 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.

The 316SS construction pressure gauges are good in use on demanding applications where corrosion resistance, rugged environment resistance and reliable operation are required. These gauges are ideal to use combined with diaphragm seal where re-calibration is required.

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
*P-1A-27 Dial 04,45,06:
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 20000 PSI including compound range.

*P-1A-27 Dial 25,35:
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 15000 PSI including compound range.
