Greatly improve measuring accuracy；Weighing unit using symmetrically arranged double weighing rollers and double help rolls, weigh roller outside each other by front and back
The symmetrical fulcrum of help roll, formed a structure mutually inhibited, not only increased the effective area of metering region, but be effectively reduced because
The interference of component, ensure that weighing sensor is solely subjected to perpendicular to flat in the vertical direction that belt shake, expanding force variation generate
The power in face increases payload numerical value under the constant situation of other stress surfaces, equivalent to reduce error accounting, ensure that electricity
The precision of sub- weighing belt weighs accurate；By setting weighing roller height adjustment mechanism, adjustable straps rate of tension improves metering
Precision.In addition, the weighing unit in the utility model is matched using the sensor of two same characteristics and used, it ensure that belt is transported
The identification of weighing-up wave is not fluctuated due to material and belt deviate when row；Bolt is protected by setting, weighing sensor can be protected
Not by other External force interferences such as weighing support；By the way that emat sensor device is arranged, during may make emat sensor, weighing structure is not
It shifts.
