The accuracy of
electronic balances or digital balance machines is considered the perfect
yardstick for any mass measurement techniques. The technology in the last few
decades has transformed the balance and scale construction industry from all
mechanical to electronic. Digital Balance and scale construction have witnessed
a revolutionary transformation in the last two decades. It has changed from
mechanical to total electronics, and become standard equipment for mass
They provide more user convenience than their
mechanical counterparts. Electronic scales are in use to measure a wide variety
of functionalities such as gravity check, analytical balance, digital moist
balancer, wheel balancer and many others. There various types of digital
balance available for different application requirements. Some of these types
are digital precision weighing balance, lab balance, buoyancy balance, digital
wheel balancer, digital analytical balance and others.
of Strain Gauge Technology
scaling machines use strain gauge technology for highly precise measurements.
The underlying principle is to use transducer beams that are engineered to bend
proportional force, weight, pressure etc. Depending on the technical
specifications, many transducer beams are used. The electrical resistance
experienced due to pressure, tension, weight etc. by the materials on the
weight platform, will be measured to find accurate data.
Digital Balances Work
First, you need to
understand how these balances are constructed. The principles behind balances
are different depending on the functionality. However, there are principally
two types of digital balance designs:
Electrical resistance wire type (Strain
are different, but they are common on one point, which is they measure the
applied force rather than directly measure the mass. Depending on the pressure,
weight, force etc. these balances measure the force on the weight platform.
balances utilize the electromagnetic force generated from a magnet. The
electrical resistance wire type method utilizes a change in resistance value
attached to the weighing scale that bends in proportion to the amount of force
Key Advantages of Digital Scales
Digital scales provide greater capacity and better accuracy for larger objects. It can also provide a precise weight of tiny objects.
These scales are highly reliable because they are sensitive and fast. It provides perfect weight management because of its auto-calibration technology.
These machines are easy to calibrate than their analogue counterparts. There are simple buttons that can accurately calibrate the weight.
Analytical balance is also capable of weighing unstable samples - from fluid to small animals. It can quickly and accurately calculate these weights and display the sample’s weight percentage.
Analytical balances are used in the laboratory and are capable of measuring very small samples with accuracy.
Digital Balance is
new age machine designed for accurate measurement of weight of different types
of objects – from small to heavy ones. Most of the establishments have switched
to using digital balance from the erstwhile mechanical balance. At Tradeindia a
number of sellers are maintaining a large stock of the Digital Balance to meet
the demands of buyers in all parts of India and various overseas markets.
Buyers looking forward to buy the range may send us their requirements via
email or SMS and get the best deals from here.
is the difference between analytical balance and precision balance?
balance is capable of measuring more precisely because it has higher
readability. The precision of the analytical balance and precision balances are
0.0001g and 0.1-0.01g respectively.
are the uses of digital balances?
balances are used in various industries such as pharmaceutical, educational,
food and beverage, chemical, industrial, etc.
are the internal components in the digital balances?
different components used in different kinds of balances. In electromagnetic
balance, there is a magnet attached to the metal bar. Also, there is a
microcontroller and digital circuit, which are the important parts of the
there any precautionary steps when using balances?
There are no such
precautionary steps, but the balance must be handled very carefully. A slight
damage due to dropping, throwing or any other kinds of damage can cause
permanent damage to the sensors and microcontrollers.
are the types of errors flagged for digital balance?
sensitivity errors, linearity errors, repeatability and eccentric error.
