Have you ever heard of Under Weighing Hooks or Below Balance Weighing?

This is a large section of the weighing business that is often overlooked. Of course, many weighing balances have the ability to “under weigh” by the use of a hook that is connected to the weighing mechanism, and much of the time this is used only to weigh items that are too large or bulky to fit on the platform or in the weighing chamber on an analytical balance.

But there is another sector of weighing that is more complex;

Density Determination.

Measurement Density Using a Scale

In this field, we look for the density of our material by using Archimedes Principle of weighing the item in air and then in a liquid. One of the largest industries to use this method of testing is the construction business.

Customers use this for identifying the density of anything from Bitumen in road surfaces, concrete, to core samples taken from the ground where construction is going to take place. Here, an end user will weigh the core sample suspended from the under-weighing hook, (normally in a basket with holes) in air and then, using a bath of water, suspend the core in the water and weigh it again. (Still in the basket).

Seems a  bit complicated? But, with use of a suitable “Below Balance Weighing” device, these measurements are easy to accomplish. The balance will not see the weight of the water, just the effect of the water on the object.

Note! For correct results, the water should be free of contaminants and the temperature of the water is a variable that should be taken into account.

Generally one of these “under balance weighing” balances or scales is not difficult; the customer almost always is familiar with the formulas. For instance, in the construction business often the state has already specified the tests and interestingly, what weighing equipment to use. (Certainly 0.1 g and capacities varying from 3000 g up to 20,000 g)

Density is required for many industries, all you need to do is know which balances have under-weighing capability or, in the case of analytical balances, which ones can have the density kit fitted. The more sophisticated balances have a density program included, so an end user can easily input the data he/she needs to get an accurate and consistent result. Many low capacity balances, such as analytical balances, have density kits that can be purchased; simplifying the process even more.

In fact, the more sophisticated electronic balances have a density program to lead users through the process. So! That is density in solids. There is some scratching of heads when we talk about densities in liquids. How can you do that???

Well, instead of suspending the object in a liquid such as water, you suspend an object of a known weight in the liquid to be tested, sometimes known as Gravimetric Displacement.

In conjunction with the Density Kit, an optional glass sinker enables you to determine the density of liquids. The difference of the weight of the sinker in air and in the liquid is
used to calculate the density.

To recap, the area of density determination with digital scales involves terms like “undeweighing” or “below balance weighing”. Please contact the sales team at Central Carolina Scale (919) 776-7737 or complete our Request a Quote form on the website for assistance with a particular application.

To help commemorate Adam Equipment’s 40^th anniversary, Adam Equipment has pledged a financial contribution to support the expansion of the Star School in Rwanda, through the Mission Possible global initiative.

In an effort to increase the number of students taught in the primary and secondary classrooms, the school sought to increase the building capacity through a new facility. The building will provide space for an additional 280 students to enroll in classes. This project will increase educational opportunities for the children served by Star School, giving them a chance at a better future and helping them to learn key skills that will provide a lasting effect. The project is scheduled for completion in January 2013, in time for the new term.

Adam has already presented the first of several payments to the Star School, helping to cover the cost of building a larger facility. Construction has started, with the pouring of a foundation for the new structure. This is one small way in which Adam Equipment hopes to commemorate their anniversary and give back to the global community.

For every PW analytical balance, PGW precision balance and PMB moisture balance purchased from now the until end of November*, Adam Equipment will donate an additional $15 to the Star School project. We hope you will take this into consideration as Continue reading →
