Mechanical pressure gauges SIKA MRE, MRE-g, MRE-S, etc.

Bourdon tube pressure gauges are the most common type in many areas and are used to measure medium and high pressure. They cover measurement ranges from 600 mbar to 4000 bar. The measuring element is a curved tube of a round, spiral or spiral shape, commonly called a Bourdon tube. This tube moves outward when the pressure inside the tube is higher than the external pressure, and inward when the internal pressure is lower. This movement is proportional to the measured pressure and is associated with the arrow mechanism.

Membrane pressure gauges are used to measure gases and liquids. They cover a measurement range from 10 mbar to 40 bar. The measuring element consists of one round diaphragm clamped between a pair of flanges. Positive or negative pressure acting on these membranes causes deformation of the measuring element. The amount of deformation is proportional to the measured pressure, and it is related to the mechanism of the arrow.

Pressure gauges with a capsule element are used to measure air and dry gases at low pressure. They cover a measurement range from 2.5 mbar to 600 mbar. The measuring element consists of two metal diaphragms soldered together and forming a cylindrical bellows chamber. This capsule element expands when the pressure inside the element exceeds the external pressure, and contracts when the internal pressure is lower.
