FIELD: measuring equipment.
SUBSTANCE: device for measuring aerodynamic pressure on tunnel structures contains a body (1), on the front wall of which an elastic membrane is placed (2). Inside the case (1), a measuring device is installed in the form of a laser rangefinder (3) installed in the housing (1) in such a way that its beam (4) is perpendicular to the elastic membrane (2). The housing (1) of the device is connected to the tunnel lining (5). Data transfer to the computer is carried out via the output (6) from the laser range finder (3).
EFFECT: expansion of the field of use of the device for measuring air pressure, namely the measurement of aerodynamic pressure on tunnel structures during the movement of high-speed trains.
