Abstract
The utility model discloses a weight sensor which comprises a frame. The essential of adopted technical scheme is as follows: the frame is connected with a cross beam, the crossing position of the cross beam is provided with a stain meter, the cross beam supports a carrying tablet. The utility model has the purpose of overcoming the defects of single rim deformation and imbalance in the prior art and provides the weight sensor which is provided with the cross beam and has balanced bearing force during weighting and after deformation. The utility model has a cross beam structure and balanced and stable bearing force and deformation and can effectively enhance the measuring precision and reduce to zero errors and lag errors. Because a stress deformation elastic body has a structure that the cross beam is arranged in the frame shaped like a Chinese character hui, and the integral stress deformation elastic body is a flat plate, the utility model has simple structure, convenient installation and low manufacturing cost.
Description
[technical field]
The utility model relates to a kind of sensor.
[background technology]
At present, the weight sensor that uses on the electronic scales is generally with the form of independent Metallic rod, foil gauge is installed on the Metallic rod, foil gauge connects an electronic circuit so that the distortion that foil gauge is produced converts electric signal to, because the spandrel girder stress deformation elastic body of existing sensors all is single semi-girder, and monolateral distortion when weighing, occur uneven easily, cause the biasing of application point when weighing and sensor easily, influence measuring accuracy, cause zero error occurring back and hysteresis error is bigger.
[utility model content]
The utility model purpose is to have overcome monolateral distortion in the prior art, and unbalanced deficiency provides a kind of weight sensor of distortion back stress balance when being provided with the weighing of rood beam.
The utility model is achieved through the following technical solutions:
A kind of weight sensor comprises framework, it is characterized in that being connected with on framework rood beam, is provided with strainometer at the infall of described rood beam, and described rood beam upper support has carrying tablet.
Aforesaid a kind of weight sensor is characterized in that described rood beam comprises the tie-beam that two free-ended free beams and two ends link to each other with framework respectively, and described carrying tablet is supported on the free end of free beam.
Aforesaid a kind of weight sensor is characterized in that described carrying tablet is an arch, and the arch carrying tablet comprises two carrying leg, and two carrying leg are joined with free end respectively.
Aforesaid a kind of weight sensor is characterized in that described strain counts strain ga(u)ge.
Aforesaid a kind of weight sensor is characterized in that the circular frame of described framework for sealing.
Compared with prior art, the utility model has following advantage:
1, the utility model rood beam structure, stress deformation balance, stable can effectively improve measuring accuracy, reduces back zero error and hysteresis error;
2, stress deformation elastic body of the present utility model adopts in the circular frame rood beam is set, and whole elastic body is a flat board, and is simple in structure, easy for installation, and cost of manufacture is low.

[embodiment]
A kind of weight sensor comprises the back-shaped framework 1 of sealing being connected with rood beam 2 on framework 1, is provided with strain ga(u)ge 3 at the infall of described rood beam 2, and described rood beam 2 is provided with carrying tablet 4.The tie-beam 202 that the free beam 201 that described rood beam 2 comprises two free ends 203,204 and two ends link to each other with framework 1 respectively, described carrying tablet 4 is supported on the free end 203,204 of free beam 201.
Described carrying tablet 4 is an arch, and arch carrying tablet 4 comprises that two carrying leg, 401,402, two carrying leg 401,402 join with free end 203,204 respectively.
When weighing, pressure F is pressed on the carrying tablet 4, and carrying tablet 4 passes to pressure on the free end 203,204 of rood beam 2 from two carrying leg respectively, makes free beam 201 produce the transverse stress distortion, pressure is delivered on the tie-beam 202 from free beam 201 simultaneously, makes it to produce stress deformation longitudinally.Have the sensor stress deformation balance, stable of rood beam 2 like this, can effectively improve measuring accuracy, reduce back zero error and hysteresis error; The stress deformation elastic body adopts in the circular frame rood beam is set, and whole elastic body is a flat board, and is simple in structure, easy for installation, and cost of manufacture is low.
