Description
Technical field
The utility model relates to electronic balance technical field, especially a kind of Novel electronic balance for pharmaceutical industry.
Background technology
People are being 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.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, the Novel electronic balance that precision is high.
The utility model solves the technical scheme that its technical matters adopts: a kind of Novel electronic balance, there is scale body, described scale body is built-in with the bar of weighing, bar one 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, on coil former, be arranged with coil, described coil former is provided with the light barrier being positioned on framework, and photoelectric sensor is installed on light barrier; The described bar of weighing is connected with the scale pan after stretching out scale body; The described bar of weighing is provided with the magnet steel that is positioned at coil outside.
Further, the described scale pan is arranged with hurricane globe outward.
Further, described magnet steel is positioned in the middle of framework upper and lower surfaces.
Further, described photoelectric sensor comprises luminotron and the receiving tube that is separately fixed at light barrier both sides.
Measuring principle: adopt closed loop electromagnetic force equilibrium principle.On the scale pan, put after weight, framework deforms, and make to weigh bar and coil move down, and the light barrier of weighing on bar moves up.The displacement of light barrier changes the light amount that photoelectric sensor receiving tube receives, thereby has Voltage-output.This voltage is converted to the electric current in tickler through a series of metering circuits.According to left-hand rule, in magnetic field, there is the coil that electric current flows through 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 beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, adopt electromagnetic force equilibrium principle, are provided with hurricane globe, have improved the precision of electronic balance, have and weigh the advantages such as quick, easy to use.
