Barograph mit Gehäuse in Buche; mahagonifarben gebeizt

A Barograph is a measuring device which records the timing of the air pressure on a paper covered on a drum. The resulting curve is called "barogram". The evaluation of the barogram can give to the expert evidence of future weather development.

In particular, are often found on ships barograph. Barographs play in aviation, in particular glider, a role. Then, however, often spoken of a level recorder. Since the air pressure decreases with altitude is known, the altitude profile of the flight can be analyzed after landing. There is also Barographs that register the air pressure history on a disc, or electronic barographs where the barogram appear on a (LC) display.

Aneroidbarographen serve the continuous recording of air pressure. The sensing element is a 7x Diaphragms sentence. It is made of a corrosion-resistant copper-beryllium alloy, which has proven itself due to their excellent elastic properties for years for pressure measurement well. Aging, hysteresis and elastic aftereffect are practically non.

The main features of the barograph are:

• 7x membrane cans set
• corrosion-resistant, elastic material
• good measurement accuracy (± 0.5 hPa)
• long-term stability
• temperature compensated
• Reversible (1d - 7d) mechanical movement
• high reliability
• maintenance-free
