Description
Technical field
The utility model is magnetic levitation liquid level sensor.
Background technology
In prior art, magnetic effect liquid level sensor has three major types: magnetic float liquid level sensor, tongue tube liquid level sensor and magnetostrictive liquid level sensor.
The measuring principle of three kinds of magnetic effect liquid level sensors is as follows respectively:
1, magnetic float liquid level sensor: in container, hollow float is connected with the outer magnetic floating drum of container by connecting rod or wire rope, magnetic floating drum be sleeved on vertical level be fixed in vessel top or container side stainless steel sleeve in, on sleeve, binding is mounted with magnetosensitive indicator, when tank fill level changes, in container, hollow float fluctuates with liquid level, by the magnetic floating drum that connecting rod or steel wire tow line connect, in vessel top or lateral vertical surface level install sleeve inter-sync rise up and down or decline, what be bundled in the magnetosensitive indicator on sleeve turns over pearl also along with magnetic buoy lifting in sleeve synchronously overturns, thus display measurement tank fill level.
2, tongue tube liquid level sensor: by tongue tube, resistance and magnetic float composition, resistance is concatenated in a string loading stainless steel pipe, a tongue tube is connected between every 2 connected resistance, the tongue tube other end links together extraction, magnetic float on sheathed catheter, vertical level is fixing in a reservoir, when magnetic float fluctuates along conduit along with tank fill level change, corresponding tongue tube adhesive, tongue tube attracted position determines the size of impedance loop, impedance loop size and height of liquid level are directly proportional, the transmitter of last sensor converts resistance signal to standard electric the signal is far passed, thus reach tank fill level measurement object.
3, magnetostrictive liquid level sensor: be made up of magnetic float, measuring staff and electronics storehouse, have signal transmitting device in electronics storehouse, measuring staff is built with magnetic susceptibility parts, i.e. waveguide filament.In sensor electronic storehouse, pulse producer produces initial current pulse, when transmitting along magnetostriction line in sensor measuring staff and waveguide filament, one is produced perpendicular to magnetostriction line (waveguide filament) toroidal magnetic field along with current impulse, when meeting in magnet ring magnetic field permanent in this impulse current magnetic field and magnetic float, namely magneto-striction phenomenon is produced---the waveguide filament be made up of magnetostriction materials, produce a torsional wave pulse, the detection mechanism in electronics storehouse is passed in this pulse back along waveguide filament with fixed speed, by measuring the mistiming of initial pulse and torsional pulses, accurately can measure the position at magnetic float place, i.e. liquid level and interface location.
Summary of the invention
The utility model is magnetic levitation liquid level sensor and measuring method thereof, and structure is simple, measure accurately, installation and maintenance are convenient, has the features such as the good and antijamming capability of explosion-proof performance is strong, to ensure online production continuity and meaning of keeping the safety in production very great.
Magnetic levitation liquid level sensor of the present utility model, by strong magnetic float, conduit, the strong magnetic weight of stainless steel counterweight, connecting rod, magnetic floating drum and upper bush, lower baffle ring forms, the sealing of conduit vertical level is arranged in container, conduit cavity and container pressure isolated, the hollow accent of conduit is placed in outside container, communicate with air, bottom head is shut, magnetic floating drum and strong magnetic weight are separately fixed at the upper of connecting rod, lower two terminations, strong magnetic weight drops in conduit upside down, lower baffle ring is fixed on conduit bottom, be enclosed within strong magnet ring in supravasal strong magnetic float relative with magnetic weight kicker magnet like pole strong in conduit, the magnetic floating drum of small end is exposed at outside conduit mouth, upper bush is enclosed within the magnetic floating drum outside conduit mouth, be connected and fixed by upper bush bottom flange is vertical with conduit upper end upper flange seat, magnetosensitive indicator and the binding of magnetostriction transmitter are fixed on stainless steel upper bush.
Further, strong magnetic weight of the present utility model is bar-shaped.
the utility model beneficial effect
1, the utility model magnetic levitation liquid level sensor, by the magnetosensitive indicator for displaying liquid level being bundled in upper bush, clear and intuitive, very clear, convenient operation personnel observe tank fill level change at any time.
2, the utility model magnetic levitation liquid level sensor, liquid level is measured with the magnetostriction transmitter being bundled in stainless steel upper bush, therefore measuring accuracy and measurement resolution are all very high, and measuring accuracy is parity with or superiority over ± 0.05%FS, and Measurement Resolution is parity with or superiority over ± 0.005%FS.
3, the liquid level signal of the utility model magnetic levitation liquid level sensor, transmit out by being suspended in the strong magnetic weight of container inner catheter cavity, conduit cavity pressure and container inner pressure isolated, cavity and air communicate, transmit the strong magnetic weight discord liquid in container contact of liquid level signal, therefore this device can be used for any inflammable, explosive, high corrosion and any of high volatilised liq has pressure non-pressure vessel to carry out level gauging, very great to safety in production meaning.
4, the utility model magnetic levitation liquid level sensor, the liquid level signal measured is delivered to container exterior by the strong magnetic weight connecting rod of the conduit cavity in a reservoir of suspending, make the magnetic floating drum be connected as a single entity with connecting rod, stainless steel upper bush inter-sync displacement on fixed container top, measure display liquid level with the magnetosensitive indicator and magnetostriction transmitter that are bundled in upper bush and convert standard electric the signal is far passed to again, electric signal is not had in container, therefore, this device explosion-proof performance is good, can be used for any high temperature, high pressure, inflammable and explosive have pressure non-pressure vessel carry out level gauging.
5, the utility model magnetic levitation liquid level sensor, the conduit cavity pressure and the container pressure that transmit liquid level signal are isolated, cavity communicates with air, when online use liquid level sensor breaks down and keeps in repair or examine and determine, do not need, container decompress(ion), clear tank and stoppage in transit, namely not affecting under the continuous ruuning situation of production, strong magnetic weight to be pulled out from conduit, sensor is taken off maintenance, qualified rear reset.Need keep as keeped in repair measuring continuity, available same specification sensor Rapid replacement.
