Wikipedia

  1. Barograph

    A barograph is a barometer that records the barometric pressure over time in graphical form. This instrument is also used to make a continuous recording of atmospheric pressure. The pressure-sensitive element, a partially evacuated metal cylinder, is linked to a pen arm in such a way that the vertical displacement of the pen is proportional to the changes in the atmospheric pressure.

  1. barograph

    A barograph is a scientific instrument used in meteorology to measure and record atmospheric pressure over a set period of time. It produces a graph or chart known as a barogram which reveals pressure changes and trends, helping in weather forecasting. It uses an aneroid barometer mechanism and a pen attached to an arm to trace a line on a rotating paper drum.

  1. Barograph

    A barograph is a recording aneroid barometer. A barograph is used to monitor pressure. The pointer in an aneroid barometer is replaced with a pen. It produces a paper or foil chart called a barogram that records the barometric pressure over time. Barographs use one or more aneroid cells acting through a gear or lever train to drive a recording arm that has at its extreme end either a scribe or a pen. A scribe records on smoked foil while a pen records on paper using ink, held in a knib. The recording material is mounted on a cylindrical drum which is rotated slowly by clockwork. Commonly, the drum makes one revolution per day, per week, or per month and the rotation rate can often be selected by the user. Since the amount of movement that can be generated by a single aneroid is minuscule, up to seven aneroids are often stacked "in series" to amplify their motion. It was invented in 1843 by the Frenchman Lucien Vidie. As atmospheric pressure responds in a predictable manner to changes in altitude, barographs may be used to record elevation changes during an aircraft flight. Barographs were required by the FAI to record certain tasks and record attempts associated with sailplanes. A continuously varying trace indicated that the sailplane had not landed during a task, while measurements from a calibrated trace could be used to establish the completion of altitude tasks or the setting of records. Examples of FAI approved sailplane barographs included the Replogle mechanical drum barograph and the EW electronic barograph. Mechanical barographs are not commonly used for flight documentation now, having been displaced by GNSS Flight Recorders.
