Weighing Scale

Weighing Scale

Introduction to Weighing Scales

Weighing Scale is a measuring device used for measuring weight of any object. Depending upon the applications the Weighing machines can be divided into Analytical balance, Precision balance and Industrial weighing scale etc. The analytical balances are used mainly in Laboratories for precise and accurate measurement. Precision scales and Industrial scales are used for variety of applications mainly in an industrial set up. The Weigh bridges are used to weigh trucks and trailers.

Importance of Accurate Weighing Scales

The importance of accurate weighing cannot be over stated. Be it for net weight compliance or measuring weights of precious materials or in manufacturing of life saving drugs, the accuracy of the weighing is the critical component in Quality assurance.

Overview of Weighing Scales

Based on the applications the Weighing scales can be divided into:

Retail Weighing scales:

The retail scales are used for retails transaction especially at a store or a mart. The capacities normally range from 6kg to 30kg

Laboratory Weighing scales:

The lab balance is used for precise measurement where measurement uncertainty is critical. The balanced used in a lab can be divided in to Precision balance, Analytical balance, Semi-micro balance and Micro balance.

Industrial Weighing scales:

Industrial scales are used to weigh a variety of material and process in a factory or a plant. The industrial scales are rugged and built to withstand the demands of an industrial environment. Platform scales, Floor scales, Crane scales, Tank weighing etc come under Industrial category. Weighbridges are used for Vehicle weighment

Weighing Machine Technologies

Load cell based Digital Scale Technology:

The Loadcells based system work on strain gauge-based principle.

EMFR Technology:

The principle of electro-magnetic force restoration (EMFR) is a combination of electrical and mechanical components. The design of EMFR Weigh Cells is based on a balance mechanism. It consists of a position indicator, a controller and an electro-magnetic drive (coil and permanent magnet).

Points to consider while choosing right Weighing scale:

  • Capacity
  • Measurement accuracy
  • Application
  • Area of usage / environment
  • Ambient condition

Types of Weighing Scales and Systems

Label Printing Scale:

Label Printing scales are used mainly used for retail applications. Also known as Supermarket scales, these scales can generate Badcode labels and can store thousands of product PLUs.

Filling System:

We have Loadcell based Filling systems to fill Tanks or drums very accurately. Filling machines come in various capacities and for various applications. The Filling machines can be customised to match any requirement.

Hopper Scale:

Hopper scales are used bulk material is moved from one hopper to other hopper of other tanks. The Hoppers are fitted with loadcells and a targeted quantity of the material can be discharged with the help of an automatic valve that operates based on the input from the loadcells.

Tank Weighing:

Tank Weighing systems are used to monitor the filling the tank or discharging material from a tank with the help of Loadcells and automatic valves. Most of the tanks can be fitted with a Tank Weighing system for accurately measuring the filling and dosing.

Lab Balance:

Lab balances are high precision weighing devices that uses EMFR technology to achieves precise and repeated results. Lab Scales are used in Quality and research labs. An example of a lab balance is Micro Balance or analytical balance.

Loadcell:

Loadcell is a devise is a gauge that converts mechanical force to analog signal. Almost all the Weighing scales operate on a loadcell principle. Loadcells are accurate and precise and can be used for multiple applications.

Indicators:

Indicator is a device that converts the analog signal of the loadcell to digital signal.

Explosion proof Scale:

Explosion proof scales are used in areas classified as Zone 1 or Zone 2.

Table Top Scale:

Table top scales are simple scales with a capacity of 6kg, 15kg or 30kg, used for a variety of applications.

Counting Scale:

Scales with the inbuilt counting functions

Waterproof Scale:

Scales used in wet conditions with IP67 protection

Stainless Steel Scale:

The scales made of SS304, for Pharma and Hygiene application

Crane Scale:

Crane scales are used with overhead craned to measure the weight of the product lifted by the crane.

Platform Scale:

Single loadcell scales with a pole mount display used to weigh bags, cartons, Drums etc. The standard capacities are 60kg, 150kg, 300kg and 500kg. This is the most common type of scale that is used for weighing.

Floor scale:

A scale with a larger platform and four load cells to weigh Pallets or bulky &heavy material often handled by forklifts. The floor scales are used in different industry environment for weighing Jumbo bags, Metal coils, IBCs, Cable drums etc.

Weigh bridge:

Weighbridges are used to weigh road vehicles to measure the net weight of the material that is in the vehicle. The net weight is derived by weighing the vehicle twice, once full and once empty thereby getting the net weight. Unmanned Weigh bridges are unattended weigh bridges that works with the help of proximity sensors and traffic lights.

FAQs on Weighing Scales

Calibration of a scale is a simple but important procedure and can be done by the user with proper guidance and required standard weights. Contact the supplier for more in for on the procedures and the legality.

Accuracy of a scale depends on

  • Calibration
  • Ambient conditions
  • Usage

Periodic maintenance and proper usage will ensure accurate measurement results.

Retail weighing solution are designed for variety of applications in retail and small Industrial weighing scales are designed to withstand high duty cycles and impact loading.
