The scales arrangement involves one of the piston-cylinder unit parts fixed to a support, while a force corresp. to the wt. for weighing acts on the other part. The one part is a cylinder part and the other part is a piston part. A device is provided which monitors the momentary pressure in the inner space and calculates the wt.. A pressure source (7) is via a valve arrangement (8) connected to the space (3), the valve arrangement being activatable by the mutual relation of the piston and cylinder parts so that with an altered distance between them the throughflow through the valve arrangement is altered. A channel (9) is arranged between the space and a reference pressure, and is located in the piston unit. It contains a throttle. |
