BACKGROUND OF THE INVENTION The present invention relates to a signal leveling device. It is suitable to signal in low-level storage tanks.

So far known low-level signaling devices are of different construction. For example, a float is made of expanded polystyrene, possibly of cork and the like. By means of lever gears, the float is not connected to the electrical signaling device, possibly, directly to the extended rod, from which the level condition can only be visually assessed. A disadvantage of these signaling devices is the need for a large float area, float connection to other lever mechanisms, large float draft, float mass instability, visual signaling, and overall less equipment reliability.

The above mentioned drawbacks are eliminated by the solution of the minimum level signaling device according to the invention, consisting of a float mounted in a conduit, a partition, a rod provided with a magnet, a tongue contact, flat pins, outlets and a signaling lamp, particularly suitable for reprographic devices on signaling the minimum condition of the developer.

The essence of the invention is that the magnet is located at the upper end of the rod, which is the lower end of the middle carrier connected to the float and the rod is inserted in the bulkhead provided in the upper part of the guide, which is provided in the lower part with the tongue contact located in the space between the magnet and the carrier and the flat pins connected to the carrier to which the signaling lamp is connected. - 2- 223 754

The solution of the present invention provides a reliable device, occupying only a small surface of the float in the reservoir, removing the lever transmission, low float immersion, simple and trouble-free operation. An exemplary embodiment of the invention is shown in the accompanying drawing, wherein the figure represents the overall configuration of the minimum signaling device. level control for reprographic devices, or other low level devices.

The minimum level signaling device consists of a magnet 2 positioned at the upper end of the rod 2, which, at the bottom end, is connected to the float 2a by a rod 6, which is inserted in the baffle provided in the upper part of the conduit. the tongue contact 8 is located in the space between the magnet 2a by the carrier 6 and the flat pins 2 connected thereto are connected to the terminals 10, 10 by which the signal lamp 11 is connected.

This device works as follows: Gradually inserting the liquid level in the reservoir 1 decreases the float 2 in the conduit 2 through the rod 2 with the rod 2 * carrier 6. Keeps the magnet 2 n8 J · "

The device of the present invention finds use in reprography on a developing device to signal a minimum level of developer development in a developer, or on other low-level devices.
