What is the function of electronic balance?
Electronic balance is an instrument used in the accurate measurement of weight of materials. Electronic balance is a significant instrument for the laboratories for precise measurement of chemicals which are used in various experiments. Laboratory electronic balance provides digital result of measurement.
What is electric beam balance?
Beam scales use a balance consisting of two platforms; one is for the object being weighed and the other is for metal or ceramic weights of a known measurement. Users add weights until they equal the weight of the object on the opposite platform, then compute the weight of the object.
What does an electric balance measure?
There are two basic types of electronic balance designs. These are based on completely different principles, but what they both have in common is that neither directly measures mass. They measure the force that acts downward on the pan. This force is converted to an electrical signal and displayed on a digital display.
What does a beam balance measure?
The triple beam balance is an instrument used to measure mass very precisely. Typically, the reading scale of the middle beam reads in 100 gram increments, the far beam in 10 gram increments, and the front beam can read from 0 to 10 grams.
What are the advantages of electronic balance?
The electronic balances are compact, easier and they can be often transported without problems . Also, the high capacity mechanical scales, such as truck scales, have the disadvantage that they aren’t transportable. But it was made small size portable electronic systems for weighing wheel load.
What are the advantages of beam balance?
– Advantages of beam balance : Doesn’t require any kind of electricity for it’s operation. This balance is very much durable.
Why is electronic balance better than beam balance?
A triple-beam balance is the best all-around mechanical balance with good sensitivity and high capacity. A digital scale is much faster and easier to use than a mechanical balance for weighing out small amounts of chemicals for chemistry.
What is the accuracy of an electronic balance?
For example, a customer may choose a balance with 0.1 mg readability (4 decimal places). The accuracy of the balance relates to the measurement uncertainty of each reading, i.e., the ± tolerance in the result. A fast, stable weighing result is not necessarily an indication of accuracy.
What is the principle of beam balance?
A beam balance works on the principle of moments. According to the principle of moments at equilibrium, the anti-clockwise moment due to the weight of an object on the left pan of the beam is equal to the clockwise moment due to the standard weights on the right pan of the beam.
How does beam balance work?
The beam balance is a device used for the determination of the mass of a body under gravitation. There are two stirrups at the ends of the beam which carries two scale pans of equal masses along with adjusting nuts. These can be adjusted to make the pointer oscillate within the scale when the balance is raised.
What is the use of balance beam?
Balance beam scales are the most accurate and common method of measuring the weight of an object or person. Different types of balance beam scales are used for different purposes. The most familiar type is found in doctor’s offices everywhere, and is used to make accurate measurements of body weight.
How is the beam balance used?
Beam balance The beam balance is used for calibrating masses in the range between 10 mg and 1 kg. The measurement resolution and accuracy achieved depend on the quality and sharpness of the knife edge that the pivot is formed from.
