BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluidized reflective transducer with multiparallel power supply and relates to automation, measurement and robotics, and addresses the fundamental task of measuring the relative perpendicular distance between the reference measurement plane, functionally associated with the selected coordinate system and the instantaneous measurement plane functionally coupled to sensor or other object in space.

For measurement of the distance as well as other physical quantities that can be transformed to change the distances, fluidized-air sensors are used in particular in difficult pre-conditions. Fluid reflective sensors are known with continuous and non-continuous operation, symmetrical as well as planar designs with parallel, convergent and divergent annular and planar supply currents.

One of their drawbacks is the relatively low output signal level relative to the power supply working medium, thereby increasing the sensitivity of the following evaluation circuit, particularly in limiting the supply pressure and the nozzle nozzle cross section.

The aforementioned drawback is solved by the fluidized planar reflection sensor of the multiplexed power supply according to the invention, the principle of which is that the fluidic reflective sensor of the distance is provided with a receiving channel, a pair of internal supply channels symmetrically disposed symmetrically. The flow channels have a rectangular flow cross section and the inner and outer feed channels from each side of the plane of symmetry of the fluid planar reflection sensor are coupled or separated to each other, and may have shaped walls of under 90 ° angles. In essence, the resulting current of the planar reflective transducer is created by the mutual arrangement of the two resp. a plurality of power supply pairs that flow out of the feed channels located symmetrically planar to the plane of symmetry of the planar transducer. By this modification, the measuring range of the sensor can be varied because, at the same time, by increasing the momentum of the supply current, the current can be divergently, convergent or flowing parallel to the sensor symmetry plane by varying the feed channel inclination.

In the accompanying drawings, FIG. 1 is a graphical representation of an existing planar reflective transducer, and FIG. FIG. 3 is a perspective view of a fluidized planar reflective distance sensor with multi-parallel power supply; FIG. 4 shows variations of the geometric variation of the fluid planar reflective sensor. Fig. 5 is a graphical symbol of a planar reflective sensor with dual power supply and a common power supply, and Fig. 6 is a graphical symbol of a planar reflective sensor with separate power supply for both internal and external power channels.

The fluid planar reflective sensor 10 in Fig. 3 comprises a receiver channel 11 of a pair of internal supply channels 121 and 122 and a pair of external supply channels 131 and 132. The receiving channel and mapping channels are planar and have a right-angled flow cross-section. The more upstream and downstream feed channel from each side of the symmetry plane can be switched or separated from one another - in dotted lines in FIG. By adding additional pairs of external power channels, multiple,
