Barographen

A Barograph is a measuring device which records the timing of the air pressure on a paper covered with 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.

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 barograph provides a pressure range of 952 ... 1052 hPa (107 hPa measuring range) available. High flexibility in Messortwahl enables worldwide use of the barograph to a Orthöhe of 3000 m. The measurement accuracy is ± 0.3 hPa.

The main features of Aneroidbarographen are:

• 7-fold membrane cans set

• corrosion-resistant, elastic material

• good measurement accuracy (± 0.3 hPa)

• long-term stability

• temperature compensated

• Reversible (1d, 14d, 7d and 31d) mechanical movement

•high reliability

• Maintenance-free
