Description
Technical field
This utility model relates to weighing apparatus verification field, and under the conditions of particularly relating to a kind of laboratory standard, Automatic balance material follows
Ring check system.
Background technology
According to JJG195-2002 " continuous integration Automatic balance (belt conveyer scale) ", JJG564-2002 " gravity type automatic charge
Weighing apparatus (quantitative automatic weigher) ", JJG648-1996 " discontinuous totalizing Automatic balance " national verification code and corresponding OIML state
The requirement of border suggestion R50, R61, R107, material test is the important component part of type evaluation test, is also cycle inspection simultaneously
The key component of inspection in determining and using.Material test is provided as follows by international recommendation: test material should be automatic
The material of weighing apparatus expection weighing or typical material, test site should be at the use scene of Automatic balance or typical test site
Carried out.
Automatic balance originates from the industrialized country that the U.S., West Europe etc. are advanced, and they are also Related product detection method states
What border was advised mainly drafts country.The metrological service of these countries establishes a collection of Automatic balance detecting system in succession, such as Britain
NWML develops continuous integration Automatic balance detection device, and Germany PTB develops automatic weight checking sorting weighing apparatus detection device, Holland
PHILIPS company has the Special Automatic weighing apparatus detection device of oneself, but all can only survey for a certain Automatic balance
Have a try and test, and generally lack exercisable various materials test method and assay device.
Some Domestic manufacturing enterprise also develops method of testing and the calibration equipment of oneself product applicable, and Anhui three is liked to think electricity
The ICS-PJZ belt conveyer scale dynamic checkout unit of sub-company limited research and development, uses the particular section on the belt feeder of conveying material
The method gathering the weight of normal loading, reaches to be equivalent to the purpose of inspection in kind, but is because chain code and the property of material in kind
Shape difference is very big, therefore cannot overcome the error that belt effect causes completely.The small-sized belt scale of Sai Mo electric corporation research and development
Material assay device, controls weighing apparatus maximum weighing 2t, and material cannot recycle, and measures scope limited, can only be to low discharge, little
Specification product is suitable for.The special belted electronic balance material assay device of the three angstroms of company's exploitations in Nanjing, level angle laying 50m,
