Dead-weight force machine
- Work Principle
By employing a special case of Newton's Second Law of Montion, both considering, atmosphere buoyant force. i.e.by subject weight as "m" : quantity to acceleration due to the gravitation field of the earth, we can obtain a standard for the quantity of the force (Gravity) as "f": f = mg(1-pa/pw)
g- location gravity acceleration
pa- location air density
pw- weight material density
- Construction Principle
The construction of the dead-weight force machine is the reverser load weight gravity to the inspected sensor. The reverser brings both tension and compression force, all weights hangs on the center for hanging, according to need to load or un-load weights, through the loading frame to convert the weights gravity to the force on the sensor.
With high accurate advantage, dead-weight force machine becomes the best, reliable choose as force value transmission.
The mass of weight can be weighed by the high precision scale or mass comparator, we just make sure the stable loading or unloading on the sensor, then the force machine will obtain the high precision.
The dead-weight force machine has been widely used in force value metrology industry, as institute metrology department, load cell manufacturer and weighing manufacturer, and so on.
- Mass loading/unloading Manner
Motor - driven independent
Motor - driven group into
- Motor - driven independent
Motor - driven independent loading technology, the loading/unloading each weight suing motor - driven independent device, basing on this feature, the machine can simply machinery construction, freely assemble weights specifications, expand loading freedom and reduce cost.
Automatic exchange mass technology
Through combinatorial optimization weight, it comes true that the least weight's combination obtains the widest measure range.
Loading automatically Controlling Technology
With programmable controlling technology, PC controlling technology and automatic testing mean, the machine can succeed in motiom controlling of big quantity as stability. The machine has the advantage with accurate and stable.
