Things to Consider When Buying Weighing Scales

A weighing scale or weight machine is the most important equipment for any industry and business. So while making a purchase, it is advisable to consider all the aspects of it. These devices are used for measuring the load of an object or an individual with a predefined scale of measurements. It’s the precision, accuracy, and repeatability of the digital weighing scales that have given reliability to deploy in various places like manufacturers, sellers, retailers, shopkeepers, and homes. Weighing scales are available in many variants on the basis of capacity, model, technology, and price. Measuring the capacity of the weighing scale ranges from a couple of micrograms to kilograms and even metric tons. Let’s discuss the features and specifications that one must consider for choosing a weighing scale.

Accuracy of Weighing Machine

Accuracy is the first and foremost key factor, which can set the worth of a weighing scale. Digital weighing scales are preferable as they're more accurate than analog scales. If you select an analog weighing scale, over a period of time, the responsiveness of spring reduces and possibly will give inaccurate values. Counting on the accuracy requirements, the deviation of the size varies between 0.5 to 0.0001% of the particular value. For applications in construction and a few manufacturing industries where the deviation of weight value is accepted, scales with high accuracy are a waste of cash. In Industries like foundries and a few gross measurement applications, a deviation of about 0.5 Kg is accepted per 100 Kg.

Analog or Digital

The design of the analog weighing scale enables it to figure out mechanisms and mechanical advantages. Analog weighing scales generally provide less accuracy in measured values. Over a period of time, the accuracy and repeatability of the weighing scale reduce and become inaccurate. Analog weighing scales are suitable for brief-term weighing applications and don’t require a power supply to work. The planning and construction of digital weighing scales enable it to work on AC/DC or battery-operated power supply. Digital weighing scales use load cells like strain gauge load cells or resistance load cells to compute the load measurement. The electronic computing circuit inside the weighing scale converts the load measurement to appropriate units. It displays the measured weight within the alphanumeric display like a 7-segment display and LCD display.

Display Of Weighing Scale

The display feature of the weight machine shows the weight of the product and measurement values in a display. The display features options for displaying the measurement values in predefined precision. The display consists of single or double-sided displays for reading values from either side. Displays are available in simple seven-segment type displays or multi-color LED displays.

Weight Capacity

The weight capacity of the weighing machine is the deciding factor and key feature that a buyer considers foremost. These weighing machines are available in various weight capacities within the ranges from micrograms to several metric tons. Most weight machines are selected depending on the industry and accuracy requirements. For instance, in the pharmaceutical industry, the weighing balance with the measuring range of micrograms to a couple of kilograms is preferable. Generally, for grocery shops and other commercial applications, digital weighing scales up to 120-150 Kg will be perfect.

Material of Weighing Scale

The material for the weighing machine differs for various sorts of applications. For pharmaceuticals and jewelry weighing scales, it should be very compact and feature a plastic body and glass finish. Weighing machines utilized in grocery stores, feature a plastic or metal body to resist corrosion. in the case of weighing machines for weighing several hundred kilograms, like in steel trading shops and in bulk weighing applications, the weighing scale features a full metal body construction with the weighing platform fabricated with steel/iron plates and steel frames for the bottom. Weighing scales also feature an anti-skid base for grip and stability during loading and unloading or weighing processes.

Operational Environment

Weighing machines are utilized in various environments like in clean rooms, tabletops of business establishments, outdoors, in dusty and moist environments, etc. Waterproof models are available for weighing liquid or weighing during a waterlogged environment. Whereas, vibration-weighing scale models are available to be used in places where there is constant vibration and mechanical movement.

Computational feature

Digital weighing scales accompany automatic features like automatic off for power saving. Price computing scales provide the computed price of the load as per the number. Memory retention and other multifunction scales are available for various applications and may be customized for industry-specific.

Application Areas

  • Quality Assurance & Testing
  • Manufacturing industries
  • Counting of pieces
  • Shipping and logistics industries
  • Research & laboratory testing
  • For usage in retail shops, supermarkets, and meat shops, etc.

With the above-discussed points, one can have a clear idea for selecting a weighing scale that matches their requirements.
