Strain rather than external force size on elastomer, are more suitable for static the weighing thereon of measured object, and its high-acruracy survey result is needed
When waiting the complete deformation of load-supporting part, and measuring the weight of vehicle in dynamic traveling, its measurement error and speed positive correlation.
Non-resistive strain weighing transducer (2), there is piezoelectric type (such as quartz, piezoelectric ceramics, piezoelectric membrane/Armouring), electricity
Appearance formula, piezomagnetic, frequency formula of shaking, gyroscope type, optical fiber type, differential variation device formula etc..By taking piezoelectric quartz weighing sensor as an example, its
Just different from resistance-strain type, quartz measurement is stress, is that the quantity of electric charge that quartz is produced is directly proportional to stress, and it is not required to
The deformation of load-supporting part is waited, dynamic measurement is its advantage, it is unsuitable complete/Absolute static is measured.
The content of the invention
In order to overcome the respective deficiency of above-mentioned prior art, weighing system, and their own strong point can be utilized, take benefit long
It is short, the utility model proposes the sound state weighing system scheme that following combination properties are more excellent.
The non-resistive such as piezoelectricity strain-type contrasts resistance strain weighing transducer/The weighing system of weighing apparatus, the two respectively has excellent
Lack short length, the former dynamic weighing excellent performance when high speed is advanced, the latter's resistance-strain type weighing system is more suitable for static title
Weight, compared with existing technology, weighing system, the beneficial effects of the utility model are --- weighing instrument described in the utility model
Table (3) is sequentially sampled and all data and is learnt from other's strong points to offset one's weaknesses according to actual conditions so that error it is smaller with/Or precision is higher, gained claims
Weight result accuracy better than in the two individually each, and actual verification.
