Scales or weighing machines are important equipment in certain industries. These equipment are used to measure the load of objects or individuals with a predetermined measurement ratio. The common scales include kitchen weighing scale, electronic weighing machine, mechanical weighing scale and body fat weight scale. The precision, accuracy and repeatability of digital scales are the focus of attention. According to capacity, model, technology and price, the scale has a variety of models to choose from. The weighing capacity can be measured from a few micrograms to a few kilograms or even metric tons. In this article, we mainly discuss the functions and specifications that must be considered when choosing a scale.
The weight weighing machine is mainly composed of three parts: load-bearing system (such as weighing pan, scale body), force transfer system (such as lever force transmission system, sensor) and display system (such as dial, electronic display instrument). In today's combination of weighing, production and sales, weighing equipment has received great attention, and the demand for weighing equipment is also increasing.
Accuracy can determine the value of the scale. Digital weighing scale is more accurate than analog weighing machine. If you choose an analog scale, the responsiveness of the spring will decrease for a period of time and may give incorrect values. According to the accuracy requirements, the dimensional deviation varies between 0.5 and 0.0001% of the specified value. For buildings and some manufacturing applications where weight deviations are acceptable, high-precision scales will waste money. In industries such as foundries and some general measurement applications, a deviation of about 0.5 Kg per 100 Kg is acceptable.
The design of the analog weighing scale gives it a mechanical advantage. Analog scales usually reduce the accuracy of measured values. Analog scales are suitable for short-term weighing applications, while digital scales can work on AC/DC or battery-powered power sources. Digital scales use load cells such as strain gauge load cells or resistance load cells to calculate load measurements.
The display function of the product weight machine mainly displays the weight and measurement value of the product on the display screen. The display has options for displaying the measured value with a predefined accuracy.
This is the decisive factor and key feature that buyers consider first. The weight range of weighing scales is usually very large. So when choosing a scale for industrial or commercial use, you must consider the accuracy requirements of your scale. Generally, for grocery stores and other commercial applications, a commercial digital scale of 120-150 Kgs is preferred.
The material of the weighing machine varies for each application.The surface of medicine and jewelry scales is usually made of glass, which can ensure that no trace components are left behind, and at the same time, it can also minimize the wear of jewelry when weighing. The weighing scales used in grocery stores are best made of plastic or corrosion-resistant metal. Because of the variety of goods in the grocery store, rigid materials can be well adapted to different weighing items.
In view of the requirements of different scales, you should examine the general requirements for the types of scales in your area, and then place an order. Our company provides you with various types of scales, welcome to consult.
