For the measurement of small positive/negative gauge pressures in gaseous media the Heavy Duty pressure gauges with capsule element can be used. Two capsule element halves soldered together form the capsule element system. The capsule element moves a predetermined distance, when subjected to pressure. A movement converts this travel into the rotary motion of the pointer.
A cover ring, triangular front ring or mounting flange are available as an option and adapt the gauge to the installation conditions. The casings are made of steel or stainless steel.
