Abstract
The electronic recording manometer is intended particularly for the graphical representation of atmospheric pressure and for use aboard ship. A generator element (1,5,6) supplying pressure-equivalent electric pulses is connected to the input of a microprocessor (2). The microprocessor (2) is provided with a clock unit (8) and a memory unit in which a calendar is stored, and which records the measured pressure values for a predetermined length of time. The outputs (4, 7) of the microprocessor (2) are connected to a liquid crystal display (3) to provide digital pressure display and graphic representation of the march of pressure, as well as being connected to a visual and/or acoustic warning device. The warning device is actuated if the pressure rate of the pressure drop exceeds a value between 0.5 and 5 mb/hour. The clock unit (8) and the memory unit can be adjusted and/or called up by means of film keyboard elements (9).
