Definitions
- the invention is not applicable to device indicators, more than that, inductive sensors are related to liquid.
- the previous level of technology is the latest in the manufacture of high-quality metals in the process of industrialization of all types of industrial equipment.
- the quality of the metal is melted • to a large extent to the degree to which the stability of the liquid metal is significantly stable.
- Unexpectedly detecting changes in the level of liquid metal may be caused by the outflow of liquid metal from the metal and the surface.
- the devices for the determination of the level of liquid metal are not known which are not compatible with this metal / patent ⁇ ⁇ 1290303, excellentrab. Part 2 published on 19 ⁇ 9.
- This device supports the emitter of - rays and their receivers. The installer installs with one side of the installation, and the receiver installs with the other. When the liquid crosses the metal, the emitter-receiver line energy is not much higher at the input of the receiver. This change is made easier by the device, and it also produces an electrical voltage-reducing signal, and this means that the communication system is inactive. However, the use of ' such devices causes the thorough protection of the operating environment to be protected.
- the most efficient products are those supplied with liquid metal, the principle of working with liquids is based on a change in the magnetic process.
- the inductive liquid metal sensor in a copper-cooled metal furnace is available for continuous steel casting (Patent dated 01/03/1978).
- This sensor provides two basic operating methods, connected to the pulse generator of the alternating current, and a non-defective one. All parts of the sensor are located on the external surface of the crystallizer.
- the task posed is solved by the fact that a producer of a liquid liquid metal containing a preferred spherical housing having a bottom and a hood and a rigid body is provided.
- a large component of an indi- vidual liquid metal product is used to increase the volume of a non-corrosive metal product.
- the most expedient way to carry out the play is to ensure that the additional open magnet is securely attached to the optional - 4 - A plate that is wafting the centering elements, and is shared by its members in a non-magnetic plate of an open magnetic drive.
- the magnetic plate is open-circuited magnet may be secured by a fixed negative circuit with two channels.
- a mobile, non-magnetic, non-magnetic plate must be filled in such a way that its thickness is not made up of a large bottom of the furnace.
- the product shown on the drawing shows - - The level of the hard metal, as per the invention.
- the 5 hard drive is secured to a non-magnetic plate 8 with paths 9 and a continuous bottom 2 of base I.
- Non-Magnetic Plate 8 - - Must be at least the thickness of the bottom of the housing 4, the bottom of the housing 4 must have a thickness of 2 to 5 mm. So, plate 8 must have a thickness of 2 to 6 mm, respectively.
- a non-magnetic plate 8 may be locked up in a permanently mobile housing I with the help of a safety switch or welding.
- the additional displaced magnet II I- * I have to displace the Partition of the main housing I with a separate, non-removable unit.
- the claimed IDC sensor is operated in the following manner.
- the intentional use of the proposed inductive sensor is a liquid metal which makes it easy to use the a high degree of accuracy of the liquid metal in the crystallization process.
- the proposed sensor may be used in the electrical industry for the purpose of controlling the level of liquid metal, for example, ⁇ aib ⁇ lee tseles ⁇ b ⁇ azn ⁇ ⁇ i- Menen iz ⁇ b ⁇ e ⁇ eniya ⁇ i ele ⁇ shla ⁇ v ⁇ m, ⁇ lazmenn ⁇ -Ay g ⁇ v ⁇ m, ele ⁇ yan ⁇ -luchev ⁇ m ⁇ e ⁇ e ⁇ lava ⁇ , ele ⁇ shla ⁇ v ⁇ y sva ⁇ e and ele ⁇ shla ⁇ v ⁇ y na ⁇ lav ⁇ e me ⁇ all ⁇ v for ⁇ ede- Lenia u ⁇ vnya zhid ⁇ g ⁇ me ⁇ alla in ⁇ is ⁇ alliza ⁇ a ⁇ .
