BOURDON TUBE PRESSURE GAUGES
BOURDON TUBE PRESSURE GAUGES
Wika Instruments offer Bourdon Tube Pressure Gauges. It is circular-shaped tubes with an oval cross-section. The pressure of the media acts on the inside of this tube. The end of the tube moves, this movement being a measurement for the pressure. A pointer indicates this movement. The bourdon tube bent at an angle of approximately 250° is used for pressures up to approx 60 bar. It can only be protected against overload to a limited extent. For particularly difficult measuring operations the pressure gauge can be provided upstream with a chemical seal as separation or protection system. The pressure ranges are between 0 ... 0.6 and 0 ... 4,000 bar with a reading accuracy (or class) from 0.1 to 4.0%.
