We offer 2 main systems for your low pressure measurements: capsule pressure gauges and diaphragm pressure gauges.
Capsule systems are used to measure air and dry gases at low pressures. They cover measuring spans from -600 to 600 mbar. The measuring element consists of two metal diaphragms soldered together to form a cylindrical bellows chamber.
Diaphragm systems consist of one circular diaphragm clamped between a pair of flanges. They are designed to measure pressure or vacuum of viscous, sedimentous, crystallisable or corrosive fluids. Compared to the bourdon tube system they are more robust and are better able to withstand overpressure or aggressive fluids.
