Abstract
The utility model relates to a magnetic force type liquid level sensor capable of outputting continuous resistance signals. The utility model is composed of a protection sleeve pipe 1, a float barrel 2, a magnetic loop 3, a bottom plate 4, a copper pipe 5, an insulated wire 6, a resistance wire 7 and an iron core 8. When the magnetic float barrel can float along with the liquid level up and down, the iron core which is sheathed on the copper pipe and the resistance wire in the protection sleeve pipe can be influenced by the magnetic force to synchronously slide up and down, so that the change of the liquid level can be converted into the change of the resistance at an output terminal. The utility model can output the linear resistance signals which have high accuracy. The utility model and a moving-coil instrument can together form a storage tank which can resist various acids, alkalis and other liquids or can form a liquid level continuous displaying and regulating device in a reaction vessel. The utility model has the advantages of simple structure and convenient fabrication, installation, and maintenance.
Description
The utility model is the magnetic-type liquid level sensor of the continuous resistance signal of an output.
Present magnetic-type liquid level sensor, characteristics are to carry out or multi-point sampler liquid level at 2, its shortcoming is to export liquid level signal continuously.
The utility model is to have overcome above-mentioned deficiency and a kind of improved magnetic-type liquid level sensor is provided.
Below in conjunction with accompanying drawing technical solution of the present utility model is specifically described as follows:
The utility model liquid level sensor comprises protecting pipe 1, floating drum 2, magnet ring 3, base plate 4, protects copper pipe 5, insulated conductor 6, resistance wire 7, iron core 8 are arranged in the grand celebration sleeve pipe.
Have 1 center pit and 1 eccentric orfice on the core section, copper pipe passes the core center hole and is fixed between protecting pipe upper flange center pit and the bottom center hole, resistance wire passes the iron core eccentric orfice, and the upper end is fixed on the protecting pipe upper flange, and the lower end is connected with the insulated conductor lower end of passing copper pipe.
Advantage of the present utility model is to provide a kind of continuous resistance output signal.
The drawing of accompanying drawing is described as follows:
In the accompanying drawings, marking each numeral is expressed as follows respectively:
1. pillar, 2. floating drum, 3. magnet ring, 4. base plate, 5. copper pipe, 6. insulated conductor, 7. resistance wire, 8. iron core.
Embodiment: have ring flange and container to carry out flange on the protecting pipe and be connected.Protecting pipe can be made with stainless steel, tetrafluoroethene pipe, and floating drum can be used stainless steel, tetrafluoroethene manufacturing, and magnet ring is made with permanent-magnet steel, and iron core can carry out copper facing.The upper end of copper pipe and insulated conductor is connected to lead-out terminal respectively, output resistance by connection terminal through copper pipe, iron core, resistance wire, insulated conductor to another connection terminal.
When floating drum was in the liquid level lower position, the iron core in the protecting pipe was subjected to floating drum magnet ring suction affects, is in the resistance wire lower position, and output resistance is a resistance wire lower limit resistance R., when floating drum rose with liquid level, iron core was also along with last cunning, and it is big that output resistance becomes, and prescribes a time limit when floating drum rises to liquid level, and iron core also rises to the upper limit of resistance wire, and output resistance is upper limit resistance R g.
The linear resistance signal of this device output, the degree of accuracy height.Can form that liquid level shows and regulating device continuously in the basin of anti-various acid, alkali and other liquid or the reactor with moving-coil instrument.It is simple in structure, and manufacture, installation, maintenance are convenient.
