Digital Balance

Digital Balance

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 measurement techniques.

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.

Use of Strain Gauge Technology

Most digital 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.

How 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: 

• Electromagnetic balancing
• Electrical resistance wire type (Strain Gauge Technology)

Both principles 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.

The digital 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 applied.

 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.

FAQs:

What is the difference between analytical balance and precision balance?

An analytical 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.

What are the uses of digital balances?

These weighing balances are used in various industries such as pharmaceutical, educational, food and beverage, chemical, industrial, etc.

What are the internal components in the digital balances?

There are 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 balance.

Are 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.

What are the types of errors flagged for digital balance?

There are sensitivity errors, linearity errors, repeatability and eccentric error.
