embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in accompanying drawing 1 composition graphs 2, Fig. 3, this boiling range two-way infrared level tracking means, comprise graduated cylinder 1, fixed cover 3, described fixed cover 3 is reverse U shape, fixed cover 3 horizontal cross-arm place is inlaid with circuit control panel 10, described graduated cylinder 1 is placed in fixed cover 3 reverse U shape space, vertical arm place, two, fixed cover 3 two ends is inlaid with two infrared emission lampshade 4, two infrared receiver lampshade 5 respectively, described two infrared emission lampshades 4, two infrared receiver lampshade 5 are inside and outside respectively to be arranged, is equipped with interior infrared discharge lamps 6, outer infrared discharge lamps 8 respectively in two infrared emission lampshade 4; Interior infrared receiver lamp 7, outer infrared receiver lamp 9 is equipped with respectively in two infrared receiver lampshade 5; Described interior infrared discharge lamps 6 is corresponding with interior infrared receiver lamp 7, is radiated at 1/4 place of graduated cylinder 1, and being used for detecting in graduated cylinder has liquid and no liquid two states; Outer infrared discharge lamps 8 is corresponding with outer infrared receiver lamp 9, be radiated at graduated cylinder 1 diameter 1/2 place, be used for the concave meniscus of tracer liquid and real liquid surface two states; Described circuit board fixed cover 3, two infrared emission lampshade 4, two infrared receiver lampshade 5 and infrared discharge lamps, outer infrared discharge lamps form double light path tracking means 2.
When this boiling range uses with two-way infrared level tracking means, as shown in Figure 4, adopt two-way infrared level tracking technique, wherein the first via (interior tracking: infrared discharge lamps 6, infrared receiver lamp 7) is positioned at inside double light path tracking means 2, be radiated at 1/4 place of graduated cylinder 1, being used for detecting in graduated cylinder has liquid and no liquid two states; Second tunnel (follow the tracks of outward: infrared discharge lamps 8, infrared receiver lamp 9) is positioned at the outer survey of double light path tracking means 2, is radiated at 1/2 place of graduated cylinder 1, is used for the concave meniscus of tracer liquid and real liquid surface two states.
When in graduated cylinder during no liquid, double light path tracking means 2 is graduated cylinder bottommost (base of graduated cylinder is that lighttight material makes, and is the glass of printing opacity at 0 scale mark place): 1., the second tunnel (following the tracks of outward) output level 1. for the first via (interior tracking) output level;
Driven by motor double light path tracking means (2) up moves to reach graduated cylinder 0 scale place: 2., the second tunnel (following the tracks of outward) output level 2. for the first via (interior tracking) output level;
Under having liquid stream in graduated cylinder, double light path tracking means (2) in a liquid between position: 1., the second tunnel (follow the tracks of outward) output level is 2. for the first via (interior tracking) output level;
Under having liquid stream in graduated cylinder, double light path tracking means (2) is bottom tracer liquid concave meniscus: 1., the second tunnel (following the tracks of outward) output level 1. for the first via (interior tracking) output level;
Under having liquid stream in graduated cylinder, double light path tracking means (2) edge on tracer liquid concave meniscus: 1., the second tunnel (following the tracks of outward) output level is 2. for the first via (interior tracking) output level;
Under having liquid stream in graduated cylinder, double light path tracking means (2) is on tracer liquid liquid level: 2., the second tunnel (following the tracks of outward) output level 2. for the first via (interior tracking) output level;
Wherein: the two states being 1. 2. respectively level change, if be 1. low level, being 2. high level, if instead be 1. high level, is 2. low level.
Two-way is worked in coordination, and solves the problem that single channel work time error is large, makes precision higher, stable and reliable for performance.
