Abstract
The invention relates to the technical field of electronic scales, and in particular relates to a novel electronic scale applied to the pharmaceutical industry. The novel electronic scale comprises a scale body. A weighing rod is built in the scale body. A frame is arranged on one side of the weighing rod. Elastic reeds are arranged on upper and lower sides of the frame. A soft iron core sleeves the weighing rod. A coil frame is arranged outside the soft iron core. A coil is wound on the coil frame. A light barrier which is located on the frame is arranged on the coil frame. A photoelectric sensor is arranged on the light barrier. The weighing rod extends out of the scale body and is connected with a scale pan. A magnet which is located outside the coil is arranged on the weighing rod. According to the invention, the novel electronic scale has the advantages of rational design, fast weighing, convenient use and the like; an electromagnetic force balance principle is used; a windshield is arranged; and the accuracy of the electronic scale is improved.
Description
Technical field
The present invention relates to electronic balance technical field, especially a kind of Novel electronic balance for pharmaceutical industry.
Background technology
People are referred to as electronic balance with the balance of electromagnetic force equilibrium weighed object gravity.In recent years, along with the high speed development of electronic technology, electronic balance is widely applied at each production link of pharmaceutical industry.Traditional mechanical balance, have precision not high, weigh slowly, use the shortcomings such as inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of structure simple, the Novel electronic balance that precision is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Novel electronic balance, there is scale body, described scale body is built-in with bar of weighing, bar side of weighing is provided with framework, and framework upper and lower surfaces are provided with elastic spring, described in weigh on bar and be arranged with soft iron core, soft iron core peripheral hardware has coil former, coil former is arranged with coil, and described coil former is provided with the light barrier be positioned on framework, and light barrier is provided with photoelectric sensor; Be connected with the scale pan after described bar of weighing stretches out scale body; Described bar of weighing is provided with the magnet steel be positioned at outside coil.
Further, hurricane globe is arranged with outside the described scale pan.
Further, described magnet steel is positioned in the middle of framework upper and lower surfaces.
Further, described photoelectric sensor comprises the luminotron and receiving tube that are separately fixed at light barrier both sides.
Measuring principle: adopt closed loop electromagnetic force equilibrium principle.After the scale pan puts weight, framework deforms, and make to weigh bar and coil move down, and the light barrier of weighing on bar moves up.The light amount that the displacement of light barrier makes photoelectric sensor receiving tube receive changes, and thus has voltage to export.This voltage is converted to the electric current in tickler through a series of metering circuit.According to left-hand rule, the coil having electric current to flow through in magnetic field will produce electromagnetic force.On this electromagnetic force and the scale pan, the gravity of object balances each other, and under the effect of elastic spring, makes scale pan support get back to original equilibrium position.
The invention has the beneficial effects as follows: the present invention
