Laser material level instrument and using method thereof

Abstract

The invention discloses a laser material level instrument and a using method thereof. The laser material level instrument comprises a shell, wherein the shell comprises an upper protective shell, a main body and a locking protruding block, the main body comprises an upper cover covering the top of the main body, a first transparent part is fixedly arranged at a top end in the upper cover, and a large pressing ring is installed at the position, at the bottom of the first transparent part, of the top of the main body; a rubber pad is arranged between the large pressing ring and the first transparent part, the structure of an existing product is designed to be integrally cast and formed, the original material is cast aluminum, a sliding part and a spring part are removed, unnecessary connecting parts are reduced, product assembling precision is improved, and after one-time mold opening cost is paid, production cost can be greatly reduced through structure later-period purchase; the structure is simple, an L-shaped stainless steel plate is adopted inside, machining is completed through a machining center, convenience is achieved, operation is easy, the semiconductor laser is fixed, no sliding block or spring exists, assembling efficiency and assembling precision are improved, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of laser object measuring instruments, and in particular relates to a laser object level instrument and a using method thereof. Background technique [0002] Laser level meter is a new type of distance measuring equipment with high precision, fast response, large range, non-contact measurement and other advantages. The frequency is more than ten times that of ordinary measuring instruments. *DO signal output function, suitable for metallurgical steel gas tank piston monitoring, medicine, food, reservoirs, ship locks, rivers, urban water and other liquid level and level process monitoring occasions, and its large range model is suitable for granaries, mines, petrochemicals and other industrial occasions. [0003] 1. The existing laser level meter has low pressure bearing capacity, non-explosion-proof design cannot be used in dangerous explosion-proof occasions, the structure is complex, the processing is dif...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing laser level meter has low pressure bearing capacity, non-explosion-proof design cannot be used in dangerous explosion-proof occasions, the structure is complex, the processing is difficult, and complex and cumbersome procedures such as blanking, welding and fixing screw holes, finishing and polishing are required. Resulting in increased product costs and low processing accuracy;

[0004] 2. It cannot be used in many industries such as metallurgy, iron and steel gas cabinet piston monitoring, metallurgy, river, mining, pharmaceuticals, food processing, etc. The standard analog circuit current 4~20mA and the measured value of the laser level meter can output signals linearly, resulting in The signal acquisition terminal such as PLC or DCS cannot signal the real-time data measured by the laser;

[0005] 3. The existing technology is only aimed at the liquid level measurement of industrial reactors, the function is simple, and it cannot be applied to the piston monitoring of metallurgical steel gas tanks at the same time. In other industries such as metallurgy, rivers, mines, pharmaceuticals, and food processing, there is a lack of setting ranges and upper limits. , set lower limit, set offset, lack of set current offset, lack of set measurement interval, lack of safety distance
