Abstract
The utility model relates to a top mounted liquid level measurement switch of liquid storage pot, electronic control device including setting up in nonrust steel outer shell is used for receiving the liquid -level probe that the electronic control device sent ultrasonic signal with connecting below the electronic control device, liquid -level probe is the naked end formula structure of Y -type of downward orientation, inside transmission sensor, the receiving sensor of being equipped with respectively of left and right opposite face of the naked end formula structure of Y -type, transmission sensor and receiving sensor passing signal line are connected with the electronic control device. The utility model discloses the setting of scheme through launching sensor and receiving sensor makes its reliability service, not influenced by viscidity, is adapted to to install at jar body top, and easily liquid dropping avoids the water bridge to produce and leads to the problem of misjudge, and measuring result is effectively accurate and signal transmission distance is short, and sensitivity is high, to meet customer needs.
Description
Technical field
This utility model relates to a kind of liquid level emasuring device, particularly relates to a kind of installed at top of liquid storage tank level gauging switch, belongs to the canned field of measuring technique of liquid.
Background technology
Supersonic liquid level report to the police mainly by transmitting and ultrasonic pulse, by calculate, compare detection signal change, record the change of liquid level.The characteristic that existing external application supersonic switch is unified all cannot be avoided the impact of environmental factors, owing to transducer frequency and sensitivity all can be had an impact by environment factor impact, causes instrument to judge by accident.The most existing ultrasonic liquid level switch the most only has a sensor, its sensitivity, and response time is delayed, it is impossible to meet demand.
A kind of double-sensing ultrasonic liquid level switch as invention entitled in Chinese patent, Application No. 201520956487.0, in this patent application scheme, liquid-level probe is inwardly to open reeded bar shape structure on periphery；There is problems with in current this liquid-level probe structure, if be arranged on tank body top, after liquid level reduces, can form water bridge between the grooves due to liquid adsorption, cause erroneous judgement, be delayed the detection time, causes detection inaccurate.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and this utility model provides a kind of installed at top of liquid storage tank level gauging switch, it is easy to liquid drips, it is to avoid the problem that water bridge produces and causes erroneous judgement.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of installed at top of liquid storage tank level gauging switch, including the electronic-controlled installation being arranged in stainless steel casing and be connected to send below electronic-controlled installation the liquid-level probe of ultrasonic signal for receiving electronic-controlled installation, described liquid-level probe is the naked end formula structure of fork-shaped downwardly；Inside the left and right opposite face of described fork-shaped naked end formula structure, it is respectively equipped with emission sensor, receives sensor；Described emission sensor and reception sensor are connected with electronic-controlled installation by holding wire.
Improve further as this utility model, in described liquid-level probe, have wire lead slot；Described holding wire is embedded in wire lead slot.
Improving further as this utility model, described liquid-level probe uses stainless steel to make.
Improving further as this utility model, the joint face between the left and right opposite face of described fork-shaped naked end formula structure is arcwall face；Described left and right opposite face is respectively vertical vertical.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
The installed at top of liquid storage tank level gauging switch of this utility model scheme, by emission sensor and the setting of reception sensor, make its reliability service, not by viscous effects, it is adapted to be arranged on tank body top, it is easy to liquid drips, the problem avoiding water bridge to produce and to cause erroneous judgement, measurement result accurate and effective and signal transmission distance is short, highly sensitive, meet user's request.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of installed at top of liquid storage tank level gauging of the present utility model switch.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Described in the utility model a kind of installed at top of liquid storage tank level gauging switch as shown in Figure 1, including the electronic-controlled installation 1 being arranged in stainless steel casing and the liquid-level probe 2 being connected to send below electronic-controlled installation 1 ultrasonic signal for receiving electronic-controlled installation, liquid-level probe 2 uses stainless steel to make.Liquid-level probe 2 is fork-shaped naked end formula structure downwardly；Left and right opposite face 3 inside configuration in described fork-shaped naked end formula structure is respectively equipped with emission sensor 4, receives sensor 5；Described emission sensor 4 and reception sensor 5 are connected with electronic-controlled installation 1 by holding wire 6；Electronic-controlled installation 1 is utilized to launch the pulse signal of a standard frequency to emission sensor 4, emission sensor 4 is converted into acoustic signals through the left part of fork-shaped naked end formula structure, after propagate in atmosphere or propagate in a liquid and receive on sensor 5 being passed directly to through fork-shaped naked end formula structure right part；It is changed into the signal of telecommunication and passes to electronic-controlled installation 1 and carry out computing and judge liquid or aneroid by receiving 5 acoustic signals of sensor again, equal reliability service in any liquid, not by viscous effects, measurement result accurate and effective and signal transmission distance is short, highly sensitive, it is possible to meet user's request.
Wire lead slot 7 is had in liquid-level probe 2；Described it is embedded in wire lead slot 7, emission sensor 4, reception sensor 5 and holding wire 6 are separately positioned in corresponding wire lead slot 7, detection part is made not expose with holding wire 6, not with detection physical contact between media, more dangerous oil product can be detected, including having the slight liquid tying layer, and shelf life is longer.
Joint face between the left and right opposite face of described fork-shaped naked end formula structure is arcwall face；Described left and right opposite is respectively vertical vertical, is adapted to be arranged on tank body top, it is easy to liquid drip, it is to avoid water bridge produce and cause the problem of erroneous judgement, measurement result accurate and effective and signal transmission distance is short, highly sensitive, meet user's request.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
