Description
HAWK 62B series capsule system pressure gauges are designed to measure low pressure from 6 inH2O to 15 PSI. These gauges 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 gauges are ideal for use in corrosive and aggressive gas. The stainless steel case is excellent withstanding rugged environment.
Typical Applications
- Everywhere low pressure and vacuum measurement is required
- Medical and pharmaceutical industry
- Industrial OEM equipment
- Burner and gas combustion service
- Heating Ventilating
- Air conditioning filtration
