Pneumatic dimensional measurement device Solex Metrology, PNEUMATIC VERSION, Pneumatic metrology is a dimensional measurement technique for parts, presenting two important advantages:, - the great measurement precision, - measurement speed, This device is used for dimensional control of parts with holes whose dimensions must comply with very tight tolerances, parts that cannot be touched due to their surface condition, or parts with complex geometry., It has thus been present for many years in industrial sectors such as biomedical (prostheses), cosmetics (sprays), pharmaceuticals (dosing pumps), aerospace or automotive (mechanical parts), where it is recognized for its robustness, reliability and very high measurement precision., PRINCIPLE OF OPERATION, The principle is based on a pneumatic flowmeter that operates by direct reading of the drop or rise in pressure corresponding to the change in flow at the level of an orifice or a leak., The regulator maintains a strictly constant pressure. The air passes through the head nozzle and exits through the control orifice. The cross-section of the head nozzle is constant and that of the orifice varies with the dimension of the measured parts, which causes pressure variations between the head nozzle and the orifice, recorded by the devices pressure gauge.
