The Heavy Duty pressure gauges with capsule element are used to measure small positive/negative gauge pressures in gaseous media. The capsule element system consists of two capsule element halves soldered together. When subjected to pressure, the capsule element moves a predetermined distance. This travel is converted by a movement into the rotary motion of the pointer.
The gauges can be supplied with a cover ring, triangular front ring or mounting flange as required for the installation conditions. The casings are avaliable in steel or stainless steel.
