These capsule pressure gauges are used when extremely-low pressures must be displayed on site. The instruments can be overloaded up to 50 times the full scale value without any problems.
The large effective area of the two welded, radially corrugated diaphragms of the capsule element allows the reliable measurement of the smallest pressures.
These measuring instruments, made entirely of stainless steel, are suitable for gaseous, aggressive media.
The capsule pressure gauge of model 632.51 has been qualified and manufactured in accordance with EN 837-3.
