Abstract
The invention provides a kind of simple in structurely, can control the liquid level detection electrode of high viscosity conductive liquid.Have three holes on the probe fixing body, be equipped with respectively long, in, short three probes, the probe outside is with insulating sleeve, making can not conducting between three probes.When middle probe all contacts liquid level with long probe, middle probe and long probe conducting, when short probe all contacts liquid level with long probe, short probe and long probe conducting.The present invention can be fit to any Level Detection with conductive liquid, especially is suitable for the Level Detection control of the out of contior jam of float-ball type liquid level gauge, the contour thick liquid of peanut butter.
Description
Technical field
The present invention relates to a kind of liquid level detection electrode, refer more particularly to the Level Detection and the control of high viscosity energy conducting liquid.
Background technology
In the filling apparatus of can milk, fruit juice, oil, the liquid level in the fluid cylinder can detect control with the float-ball type liquid level gauge.Accompanying drawing 1 is a kind of front view of common float-ball type liquid level gauge, and its structure comprises: ball float (1), bar (2), upper limit jump ring (3) lower limit jump ring (4).Be provided with one high and one low two groups of contacts of being made up of magnetic conductive metal in the bar (2), ball float is equipped with magnet in (1).When liquid level descends, ball float (1) descends under buoyancy, magnet when dropping to low liquid level in the ball float (1) makes the low level contacts adhesive, the float-ball type liquid level gauge sends low liquid level signal, when liquid level rises, ball float (1) buoyancy is risen down, and the magnet in the ball float when rising to high liquid level (1) makes the adhesive of high-order contact, and the float-ball type liquid level gauge sends high liquid level signal.The shortcoming of this float-ball type liquid level gauge is: when liquid viscosity when higher, ball float (1), even can not rise or descend because the sensitivity meeting that the influence of liquid viscosity is risen and descended reduces greatly with bar (2), just can not reach the purpose of controlling liquid level.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of simple in structure, can control the liquid level detection electrode of high viscosity conductive liquid.
For solving the problems of the technologies described above, the technical solution used in the present invention is: have three holes on the probe fixing body, be equipped with respectively long, in, short three probes, the probe outside is with insulating sleeve, making can not conducting between three probes.When middle probe all contacts liquid level with long probe, middle probe and long probe conducting, when short probe all contacts liquid level with long probe, short probe and long probe conducting.
The invention has the beneficial effects as follows: simple in structure, can be fit to any Level Detection with conductive liquid, especially be suitable for the Level Detection control of the out of contior jam of float-ball type liquid level gauge, the contour thick liquid of peanut butter.
Description of drawings
Fig. 1 is the main TV structure synoptic diagram of the float-ball type liquid level gauge described in the background technology.
Fig. 2 is a main TV structure synoptic diagram of the present invention.
Among Fig. 1: 1. ball float, 2. bar, 3. upper limit jump ring, 4. lower limit jump ring.
Among Fig. 2: 1. probe, 2. insulating sleeve, 3. probe fixing body, 4. fixed cover, 5. insulation sleeve.
Embodiment
Among Fig. 1, long, in, short three probes (1) surface is with insulating sleeve (2), three probes (1) are installed in respectively in the hole of probe fixing body (3), the probe fixing body has screw thread on (3), be connected with fixed cover (4), probe fixing body (3) is made with insulating material, to guarantee the not conducting voluntarily of three probes, insulation sleeve (5) is housed above the probe fixing body (3).
The principle of work of above-mentioned liquid level detection electrode is: below liquid level, when middle probe all contacted liquid level with long probe, middle probe and long probe were communicated with long probe all the time, and when short probe all contacted liquid level with long probe, short probe and long probe were communicated with.
Claims (1)
1. liquid level detection electrode, comprise: probe (1) surface is with insulating sleeve (2), be installed in the hole of probe fixing body (3), fixed cover (4) is housed on the probe fixing body (3), insulation sleeve (5) is housed above the probe fixing body (3), it is characterized in that: probe be divided into long, in, short three.
