ABSTRACT:
A device for measuring thickness of storage cell plates in sorting comprises a hollow case (1) divided by a movable diaphragm (2) into a measuring chamber (3) and a counterpressure chamber (4). The measuring chamber (3) connects via an outlet duct (7) with a sensing element (8) which has a space for accommodating a storage cell plate (11) to be measured. The counterpressure chamber (4) connects via an outlet duct (16) and a counterpressure nozzle (17) with a transmitting element (18) which is fixedly attached to the movable diaphragm (2) and is constructed as a wedge (19) with a blind (21) fixedly attached thereto. The device further includes an indicator of travel of the transmitting element (18) constructed as a multirange photorelay (24) acted upon by the blind (21). The wedge (19) has provision for varying the angle of the working surface (20) thereof relative to the counterpressure nozzle (17) for the purpose of adjusting the transmission ratio of the transmitting element (18) and varying the travel of the blind (21) with respect to the photorelay (24).
