Through the application of the throw-in type liquid level transmitter, the cable can be prevented from being twisted and being knotted due to rotating of media, and therefore damage is avoided, and corrosion of the media on the cable is avoided.
Description
Technical field
The present invention relates to a kind of throw-in type fluid level transmitter.
Background technology
Fluid level transmitter, is again liquid level gauge, is a kind of pressure transducer of measuring liquid level.It is the proportional principle of height to this liquid based on surveyed fluid pressure, adopts diffuse si sensitive element or ceramic condenser presser sensor sensor, static pressure is converted to electric signal, then passes through temperature compensation and linear revise, changes into standard electric signal.Fluid level transmitter is widely used in the level gauging of the various media of the systems such as petrochemical complex, metallurgy, electric power, pharmacy, water supply and sewage, environmental protection and industry.
But existing throw-in type fluid level transmitter, as shown in Figure 1, adopts the mode of box body 1 direct outlet conventionally, while measurement, cable 2 and sensor 3 are all immersed in measured medium, and this kind of throw-in type fluid level transmitter is useful in static pressure container; But having some operating modes is that container contains stirrer, because the medium in container needs to stir, therefore, stirrer can be opened and carry out agitated medium at set intervals, the cable 2 of existing throw-in type fluid level transmitter is flexible, when stirring, can produce rotation with medium, sensor 3 easily and stirrer is tied a knot and damage sensor 3.
Summary of the invention
The technical problem to be solved in the present invention is can produce the defect of knotting and distortion with medium rotation in order to overcome prior art cable, and a kind of throw-in type fluid level transmitter is provided.
The present invention solves above-mentioned technical matters by following technical proposals:

Embodiment
Enumerate preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
Throw-in type fluid level transmitter as shown in Figures 2 and 3, comprises a box body 1, a sensor 3 and a cable 2 being connected with box body 1 and sensor 3 respectively, and cable 2 is coated with a containment vessel 4.
Containment vessel 4 comprises a crossover sub 41 and a connecting rod 42, and crossover sub 41 tops are provided with screw thread, mates with the screw thread of box body 1 lower end.Rotation crossover sub 41, just can couple together crossover sub 41 and box body 1.Because some material such as is inconvenient to weld at the operation, so can better be connected with the box body 1 of various materials by the screw thread of crossover sub 41.
The upper end of connecting rod 42 is connected by laser bonding with crossover sub 41, and lower end is also connected by laser bonding with sensor 3.After welding, box body 1, containment vessel 4 and sensor 3 become a fixing entirety, can not produce any distortion because of extraneous medium rotation.
Sensor 3 bottoms are provided with a diffuse si core body 32 being electrically connected with cable 2.Gaging pressure that can convenience and high-efficiency by diffuse si core body 32.Diffuse si core body 32 tops are provided with a clamping cap 31, and clamping cap 31 is pressed on diffuse si core body 32 bottom of sensor 3, thereby prevent that diffuse si core body 32 from departing from original position.
In the present embodiment, described magnification circuit plate 11 electronic components such as grade are set in box body 1, due to not contact medium of box body 1, just can better protect magnification circuit plate 11 electronic components such as grade, avoid the erosion of liquid.
In the present embodiment, the material of box body 1 is aluminium.Aluminium material is light, and plasticity is strong.Can also make described box body have explosion prevention function.User can directly buy the box body 1 of aluminum, very convenient.
Because many media have corrosive power, on containment vessel 4 outside surfaces of the present embodiment, cover an erosion shield.Erosion shield can increase the corrosion resistance of described containment vessel.
On the present embodiment box body 1, be provided with one for showing the display screen 12 of liquid level information, by display screen 12, user can understand liquid level information timely and conveniently.
On lid 13 and lid 14, be provided with screw thread, can open, facilitate user to adjust.
In the present embodiment, the connection setting of the components and parts such as magnification circuit plate 11, display screen is all the conventional gimmick in this area, therefore do not repeat at this.
As shown in Figure 4, the difference of the present embodiment and embodiment 1 is, the containment vessel 4 in the present embodiment is a long straight-bar.Containment vessel 4 can be threaded connection or welding is connected with box body 1 and sensor 3.Other parts of the present embodiment are all identical with embodiment 1, therefore do not repeat at this.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these embodiments, but these changes and modification all fall into protection scope of the present invention.
