Abstract
The utility model relates to a two sensing ultrasonic wave liquid level switch, include that the electronic control device in the stainless steel shell is used for receiving the liquid level probe that the electronic control device sent ultrasonic signal with connecting below the electronic control device, the liquid level probe is inside division notched cylinder column structure on the outer disc, inside transmission sensor and the receiving sensor of being equipped with respectively of recess relative up -down face, transmission sensor and receiving sensor passing signal line are connected with the electronic control device. The utility model discloses a transmission sensor and receiving sensor's setting makes its reliability service, not influenced by viscidity, the accurate effective and signal transmission distance weak point of measuring result, and sensitivity is high, to meet customer needs.
Description
Technical field
The utility model relates to a kind of liquid level metering device, relates in particular to a kind of double-sensing ultrasonic liquid level switch, belongs to liquid tank packing technique field.
Background technology
It is mainly transmitting and the ultrasonic pulse utilizing that supersonic liquid level is reported to the police, by calculating, and the relatively variation of detection signal, the variation that records liquid level. The characteristic that existing outer subsides supersonic switch is unified all can not be avoided the impact of environmental factor, because environment factor impact all can have impact to transducer frequency and sensitivity, causes instrument to judge by accident. In addition existing ultrasonic liquid level switch all only has a sensor, its sensitivity, and the response time lags behind, and can not satisfy the demands.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and the utility model provides a kind of accurate and effective, highly sensitive double-sensing ultrasonic liquid level switch.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double-sensing ultrasonic liquid level switch, be included in the electronic-controlled installation in stainless steel casing and be connected to electronic-controlled installation below the liquid-level probe that sends ultrasonic signal for receiving electronic-controlled installation, described liquid-level probe is on periphery, inwardly to open reeded bar shape structure; Be respectively equipped with emission sensor and receiving sensor in the upper and lower opposite face of described groove inside; Described emission sensor is connected with electronic-controlled installation by holding wire with receiving sensor.
Further improved as the utility model, in the bar shape structure of described liquid-level probe, have wire lead slot; Described holding wire is embedded in wire lead slot.
Further improved as the utility model, described liquid-level probe adopts stainless steel to make.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The double-sensing ultrasonic liquid level switch of the utility model scheme, by the setting of emission sensor and receiving sensor, makes its reliability service, is not subject to viscous effects, and measurement result accurate and effective and signal transmission distance are short, highly sensitive, meet consumers' demand.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of double-sensing ultrasonic liquid level switch of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of double-sensing ultrasonic liquid level switch as shown in Figure 1, comprise the electronic-controlled installation 1 being arranged in stainless steel casing and be connected to electronic-controlled installation 1 below the liquid-level probe 2 that sends ultrasonic signal for receiving electronic-controlled installation 1, described liquid-level probe 2 is for inwardly having the bar shape structure of groove 7 on periphery; Shang Xia 7, opposite face inside be respectively equipped with emission sensor 4 and receiving sensor 6 at described groove; Described emission sensor 4 is connected with electronic-controlled installation 1 by holding wire 8 with receiving sensor 6.
Utilize electronic-controlled installation 1 to launch the pulse signal of a standard frequency to emission sensor 4, emission sensor 4 is converted into acoustic signals and sees through square body 3 on groove, after in air, propagate or propagate in liquid and directly passing on receiving sensor 6 seeing through square body 5 under groove; By receiving sensor 6, acoustic signals being changed into the signal of telecommunication again passes to electronic-controlled installation 1 and carries out computing and judge fluid or aneroid, in any liquid, equal reliability service, is not subject to viscous effects, and measurement result accurate and effective and signal transmission distance are short, highly sensitive, can meet consumers' demand.
In the bar shape structure of liquid-level probe, except the wire lead slot 9 that is provided with intercommunication in groove 7 parts; Described holding wire 8 is embedded in wire lead slot 9, and emission sensor 4 and receiving sensor 6 are separately positioned in corresponding wire lead slot, and test section and holding wire are not exposed, directly do not contact with detection medium, can detect how dangerous oil product, comprise the liquid with slight knot layer, and shelf life be longer.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation. All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
