Description
The utility model relates to a kind of improvement of liquid level gauge.
The automatic alarm liquid level meter that occasions such as present industrial high pressure boiler and pressure vessels for the chemical industry are used, mostly adopt electrode sensor, this sensor poor sealing performance, easily leak, particularly use in high temperature high pressure liquid, its reliability and security can not get guaranteeing, because electrode is easily corroded by fluid to be measured or give birth to dirt, cause the electrodes conduct performance to reduce, produce wrong liquid level and show or false alarm.
The purpose of this utility model provides a kind ofly installs fluid level tube on observed container, utilize the magnetic induction coil winding in the self-equilibrating float in it and the outside to produce the electromagnetic induction liquid level sensor and the self-equilibrating float of level sensing signal.
Electromagnetic induction liquid level sensor of the present utility model and self-equilibrating float, be by fluid level tube, last lower flange, float, the magnetic induction coil winding is formed, on the fluid level tube, the lower end be respectively arranged be observed that container links to each other on, lower flange, the top and the bottom, the outside of fluid level tube are equipped with holder, the outer middle side part of fluid level tube is provided with 5-25 group magnetic induction coil winding, each organizes the magnetic induction coil winding by core bar and be arranged on its outside space washer and be fixed on the holder, be provided with float in the fluid level tube, closed float internal fixation has the electromagnetism iron hoop, and be filled with tested container in identical liquid; The magnetic induction ring of magnetic induction coil winding is electrical pure iron and has breach, is wound with field coil and inductive coil on it; Inductive coil is series connection output or output in parallel.
The utlity model has that structural principle is simple, stable performance, no catabiosis, good seal performance, no leakage point is widely used in the occasions such as liquid level demonstration of high temperature and high pressure containers.
Accompanying drawing 1 is the utility model master TV structure sectional view.
Accompanying drawing 2 is the utility model magnetic induction ring and float sectional drawing.
Below in conjunction with accompanying drawing the utility model is further described; sensor of the present utility model is by fluid level tube; float; the magnetic induction coil winding is formed; the upper and lower side of fluid level tube 1 is processed with; lower flange 3; on; lower flange respectively be observed container 2 and link to each other; top and the bottom, the fluid level tube outside are equipped with holder 4; in order to fixing magnetic induction coil winding 5; the magnetic induction coil winding is provided with the 5-25 group; being installed in the fluid level tube outside goes up between the lower fixed seat; every group of magnetic induction coil winding is provided with the core bar hole; core bar 6 passes the core bar hole and is fixed on the holder; the core bar outside is with space washer 7; go here and there up and down to prevent the magnetic induction coil winding; be wound with field coil 12 and inductive coil 13 on the magnetic induction ring 11 of magnetic induction coil; the magnetic induction ring is that electrical pure iron is made; be processed with breach; breach is stuck on the fluid level tube outer wall; the setting of 5-25 group magnetic induction coil winding is such; be respectively the start coil from bottom to top at the fluid level tube outer wall; low liquid level warning coil; show coil; the high liquid level warning coil; shut down the coil and the substrate signal coil that disappears; show that coil can be provided with many groups; demonstrate the signal of different liquid levels according to user's needs; be wound with the field coil parallel-series of the identical number of turn on each magnetic induction coil winding magnetic induction ring; the number of turn of inductive coil from bottom to top increases by a certain percentage gradually; can serial or parallel connection; to reach the purpose of distinguishing two position; in order to eliminate the substrate signal in the inductive coil, the substrate signal coil that disappears should be by the reverse coiling of inductive coil, and its number of turns is the summation of inductive coil; and be in series with inductive coil, inductive coil is output as zero (to connect field coil) when energized.Be provided with float 8 in the fluid level tube, float is an enclosed construction, the float internal fixation has electromagnetism iron hoop 9, its inside be filled with tested container in identical liquid 10, the charge weight of liquid is suitable for just all being evaporated under normal working temperature pressure, charge into appropriate amount of fluid in the self-equilibrating float, purpose is under the high temperature of extraneous fluid to be measured and high pressure effect, generation steam and ambient pressure balance each other in the float, to eliminate outside pressure, avoid float bad by crushing, principle of work of the present utility model is such, flange of the present utility model is connected with tested container, when liquid level increases, float come-up in the fluid level tube, when the breach of the magnetic induction ring of the position of float and magnetic induction winding coincide, the magnetic field intensity maximum that electromagnetism iron hoop in the float and magnetic induction winding induce has signal output, indicates liquid level by display device.Flange of the present utility model, fluid level tube, core bar, upper and lower holder, space washer is non-magnet material and makes, and the magnetic induction ring of magnetic induction coil winding is that silicon steel sheet is made.
