<p>The dispenser (2) has a compressed air dispenser (4) for directing delivery of compressed air from a compressed-air generating device (5), where pressure of an air jet is greater than ambient air pressure. A sensor detects produced physical parameters such as pressure, temperature, velocity or pulse of an automatic height-adjustable output unit (1) while reducing the pressurized air corresponding to the compressed air dispenser. A measuring sensor (7) is equidistantly arranged in the compressed air dispenser. The measuring sensor is selected from one of a pressure sensor, a flow sensor, a temperature sensor and a rotation speed measuring unit.</p> |
