Description

HAWK 67L and 67B series capsule system pressure gauges are designed to measure low pressure from 0.5 inH2O to 15 PSI. These use a diaphragm capsule as its sensing element. The sensing element consists two half capsules which are soldered together. The diaphragm capsule element expands by subjecting to pressure. The expansion is converted into the rotary motion of the pointer by a movement. This motion makes users read the scale easily. The wetted parts can be in beryllium copper, brass or 316 stainless steel. All stainless steel low pressure gauge are ideal for use in corrosive and aggressive gas. The aluminum case is excellent in withstanding rugged environment.

Typical Applications

  • Process control and chemical industry
  • Medical and pharmaceutical industry
  • Burner and gas combustion service
  • Everywhere low pressure and vacuum measurement is required
  • Waste water treatment
  • Heating Ventilating
  • Air conditioning filtration
