Description

Tank gage

Technical field

Originally it is new to belong to physical measurement field, and in particular to a kind of tank gage.

Background technology

In fourth industry production process, liquid measure is commonly encountered.The purpose of level gauging mainly has two：First, pass through liquid level Measure to determine the raw material in container, product or the quantity of semi-finished product, to ensure in production without interruption needed for links Material；Another is by level gauging, whether within the limits prescribed to understand liquid level, to be normally carried out production process, Ensure quality, yield and the production safety of product.Currently used liquid level is calculated as floating type liquid level indicating, as shown in figure 1, it is root Upper and lower displacement buoys are produced with the height of liquid level this change in displacement is passed through into pulley according to the float or buoy that float on liquid level For component passes to the instruction device outside container, the position by observing instruction device just will be seen that the liquid in current container Position.But this floating type liquid level indicating needs artificial observation just to know current level, its be unfavorable for realizing computer controlled automatic, Automatic measurement.

Utility model content

It is the defects of for prior art, originally new to provide a kind of liquid level gauge.

A kind of tank gage, including floating drum 1, long arm bar 2, torque tube 3, mandrel 4, push rod 5, bascule 6 and Hall Element 8；The vertical one end for hanging on long arm bar 2 of floating drum 1, the other end of long arm bar 2 are vertical with one end of torque tube 3 It is fixed together, long arm bar 2 is supported with torque tube 3 by bearing 9, and torque tube 3 is set in outside mandrel 4, the connection of the one end of mandrel 4 One forked push rod 5, forked push rod 5 clamp one end of bascule 6, and the other end of bascule 6 connects Hall element 8, etc. Arm bar 6 can rotate around central shaft 7.

Originally new beneficial effect is：Originally it is new cleverly to make use of torque tube, changed by the angle of torque tube to reflect The change of liquid level in container, can by Hall element so as to which the liquid level change transitions of big displacement be changed for the angle of low-angle To measure this small angle change, and then by liquid level change transitions for corresponding electric signal, it is achieved thereby that the electricity of liquid level Measurement, its is simple in construction, and reliability is high, and cost is low.Computer control/prison of liquid level can be realized using this new tank gage Survey.

Brief description of the drawings

Fig. 1 is the structural representation of tank gage in the prior art；

Fig. 2 is the structural representation of this novel liquid level instrument.

Embodiment

It is new to this below in conjunction with the accompanying drawings to enable this new above-mentioned purpose, feature and advantage more obvious understandable Embodiment be described in detail, this new above and other purpose, feature and advantage will be become apparent from.Complete Identical reference instruction identical part in portion's accompanying drawing.Not deliberately accompanying drawing drawn to scale, it is preferred that emphasis is show that this is new The purport of type.

As shown in Fig. 2 this new tank gage includes floating drum 1, long arm bar 2, torque tube 3, mandrel 4, push rod 5, equiarm Lever 6 and Hall element 8.The vertical one end for hanging on long arm bar 2 of floating drum 1, the other end and torque tube of long arm bar 2 3 one end is vertical to be fixed together, and long arm bar 2 is supported with torque tube 3 by bearing 9, and torque tube 3 is set in outside mandrel 4, core The one end of axle 4 connects a forked push rod 5, and forked push rod 5 clamps one end of bascule 6, and the other end connection of bascule 6 is suddenly That element 8, bascule 6 can rotate around central shaft 7.

During this is new, the detecting element of tank gage is the floating drum 1 that part is immersed in liquid.When level change, floating drum 1 With the lifting/lowering of liquid level, lifting/lowering, floating drum 1 are vertically hung at one end of long arm bar 2, the other end of long arm bar 2 and torsion Solenoid 3, one end of mandrel 4 are fitted vertically together, and the bearing 9 by being fixed on shell is supported；Another-end of mandrel 4 For free end, for angle displacement S.The upper and lower displacement of long arm bar 2 is changed into by the angle that mandrel 4 rotates by torque tube 3 Displacement.Bascule 6 is driven around central shaft 7 through forked push rod 5 again, and then drives the Hall element 8 of the other end of bascule 6 That makees near linear in magnetic field moves up and down (under upward), so as to which the change of liquid level is converted to corresponding electromotive force signal Output.The electromotive force of output is modulated, is transformed to 4-20mA standard unified signals after amplification, record or control letter as liquid level Number.Originally it is new cleverly to make use of torque tube, changed by the angle of torque tube to reflect the change of liquid level in container, so as to by greatly The liquid level change transitions of displacement change for the angle of low-angle, can measure this small angle change by Hall element, enter And by liquid level change transitions for corresponding electric signal, it is achieved thereby that the electrical measurement of liquid level, its is simple in construction, and reliability is high, Cost is low.Computer control/monitoring of liquid level can be realized using this new tank gage.

It is new in order to fully understand to elaborate many details in the above description.But above description is only This new preferred embodiment, this it is new can be much different from other manner described here to implement, therefore this It is new not limited by specific implementation disclosed above.Any those skilled in the art are not departing from this new technique simultaneously In the case of aspects, all this new technique scheme is made using the methods and technical content of the disclosure above many possible Changes and modifications, or it is revised as the equivalent embodiment of equivalent variations.Every content without departing from this new technique scheme, according to this New technical spirit still falls within this new skill to any simple modifications, equivalents, and modifications made for any of the above embodiments In the range of the protection of art scheme.
