Device for measuring thickness of storage cell plates in sorting

A device for measuring thickness of storage cell plates in sorting, comprising a hollow case divided by a movable diaphragm into a measuring chamber and a counterpressure chamber, said measuring chamber having an inlet duct with an air flow restrictor and an outlet duct connected with a sensing element provided with a space for accommodating a storage call plate to be measured and further provided with a measuring nozzle facing toward said space, said counterpressure chamber having an inlet duct with an air flow restrictor and an outlet duct with a counterpressure nozzle the air flow resistance of which is governed by the movement of a transmitting element having an adjustable transmission ratio, rigidly connected to the movable diaphragm and adapted to actuate a transmitting element travel indicator, characterized in that the indicator of the travel of the transmitting element (18) is constructed as a multirange photorelay (24) designed for sorting storage cell plates (11) being measured, and the transmitting element (18) includes a wedge (19) to which is rigidly attached a blind (21) designed to act upon the multirange photorelay (24), said wedge (19) having provision for varying the angle of the working surface (20) thereof in relation 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).
