Precision Balances – Description

Analytical Balances

Principle and Applications

A Precision Balance is a highly accurate electronic weighing instrument used for measuring mass with greater precision than ordinary laboratory balances. Precision balances are widely

used in laboratories, pharmaceutical industries, chemical plants, jewellery industries, research centers, educational institutions, and industrial quality-control departments.

Precision balances generally provide readability from:

$0.001\text{g}\text{to}0.01\text{g}$

These balances can weigh from a few grams to several kilograms while maintaining excellent accuracy and repeatability.

Working Principle of Precision Balance

Modern precision balances mainly work on the Electromagnetic Force Compensation (EMFC) principle or high-precision load-cell technology.

Basic Working

1. Sample is placed on the weighing pan.

2. Sensor detects the downward gravitational force.

3. Electromagnetic system generates equal counter-force.

4. Electrical signal is converted into digital mass reading.

Fundamental Relation

$F=mg$

Where:

• $F$ = Force

• $m$ = Mass

• $g$ = Gravitational acceleration
