The meter is the core part of the weighbridge, and companies should pay attention to the choice of instrument when purchasing the scale. For manufacturing enterprises, the weighbridge is its main asset. The selection of the electronic platform meter can not only ease the financial pressure of the enterprise, but also effectively control the cost of production and improve the market competitiveness of the enterprise products. How to buy the floor scale meter? If your purchasing method is right, then the benefits are much more, saving both the cost of the enterprise and the service life. This article mainly proposes the type and importance of the purchase of the scale instrument, focusing on the principle of purchasing the scale instrument.
First, there must be a clear direction
When choosing an electronic platform scale, you must understand your needs: voltage, current, parameter, signal source or other types of instruments, to find out the type of instrument required to determine the direction of purchase.
Second, timely grasp the information of the electronic platform scale instrument
1. There are also a variety of instruments, such as explosion-proof, with printing, ordinary, etc., to know what they need.
2. Keep abreast of relevant information, such as the requirements of the research and technical department and other special requirements, determine the several scales that are currently popular in the market, and then find several companies that are using these instruments to conduct thorough research and find out the instruments. Technical indicators, such as reliability, stability, accuracy, accuracy, what is the actual performance in a few years of use, what type of abnormal conditions have occurred during the period, how the after-sales service of the instrument enterprise, and then the corresponding information Organize a piece of information.
3. Analyze and compare, list the performance of the respective instruments, and queue according to the performance indicators, the scale of the manufacturer, the credibility, and the after-sales service. At least three options that meet the requirements are determined, and the required instruments are publicly tendered. Under the premise that the quality meets the demand, the price is not much different, and the service is timely, the nearest manufacturer is preferred. If the products of domestic manufacturers can not meet the requirements, they can only choose imported instruments, then it is necessary to find out which type of instruments are required, whether they are general or special.
If it is a special class, then you must be very careful about foreign bans. You should leave a plan, reserve as many post-selection instruments as possible to meet your needs, or take into account the significant impact. To prevent being caught by the neck. This has happened in China. When the relationship between the two countries is friendly, it will be sold to you. If you are not good, you will not sell it, and the user will be very passive. Either the instrument fails, the domestic can not be repaired, the foreign repair time is long, the cost is high, and the impact on the enterprise is large.
Third, the principle of purchasing electronic platform scale instruments
1. Depending on the department of use, choose different grades of instruments.
For the selected instruments, we must select those products with high reputation, market-recognized, and reliable quality production. Clearly the department used by the instrument: whether it is the R&D department, the production department, the meter measurement department, or other departments. For different departments to buy different grades of instruments. For the production department, the number of instruments used will generally be relatively large. For such departments, it is not appropriate to purchase high-grade instruments with high performance to meet the needs of the use. For the production department, high indicators Not used, it is a waste of resources. This not only satisfies the production needs of the enterprise, but also saves the cost for the enterprise, and also saves potential costs. For example, if the high-grade instrument fails, the maintenance cost is not small. For the R&D department, due to the nature of its work, it is better to choose higher-end instruments to meet the needs of technical research. These departments are also the key core departments of the enterprise, and it is also a good horse. For the instrument equipped by the metering department, it is necessary to select the meter with accuracy, stability, reliability and technical parameters higher than the meter of the instrument, because it is used as a standard to ensure the accuracy of the instruments used by other departments. Make sure that the meter you are using is in good condition. In layman's terms, it is a ruler.
2. Purchase domestic electronic floor scale instruments as much as possible
Under the premise that the domestic instruments can meet the actual work requirements, the domestic instruments should be selected as much as possible. This not only reduces the direct production cost of the enterprise, reduces the waste of resources, but also reduces the potential maintenance costs. The maintenance cycle will also be compared. short. There is currently a tendency that instruments are often imported. It is undeniable that the reliability, stability and indicators of imported instruments are higher than those of domestic similar instruments. However, in terms of use, most of the functions are not used, resulting in low cost performance of the instrument, which can meet the needs of use. Under the circumstances, the price of imported instruments is often several times that of domestic instruments, and the maintenance cost is also high. In fact, in recent years, the development of domestic electronic technology has advanced by leaps and bounds, and the state has a great support in terms of instrumentation. The quality of domestically produced instruments has not been the same, and domestically produced instruments can meet most of the needs.
3. Principles for the selection of general-purpose general scale instruments
After determining the index requirements of the weighbridge instrument, select the instrument model that can meet the demand, and select the brand-name products produced by the company with high credibility, high market share, large scale and perfect service system. Buying products from the same company as much as possible has many benefits:
(1) If the instrument fails during the process of use, it can be easily deployed without affecting the normal operation. It is also much easier to repair once a fault occurs.
(2) Large purchasers will generally pay attention to the products, and the after-sales service will be in place.
(3) The intensity of the price concessions will be relatively large, saving corporate funds.
4. Special requirements for the selection of electronic platform scale instruments
If you have a lot of requirements for the stability and reliability of the electronic platform instrument, then the stability and reliability of the weighbridge should be placed at the top position, and the indicator should be placed in the second place (of course, the index must be met). For example, the instrument used in extremely cold and extremely hot environments should ensure that it can work normally in such a harsh environment. For such instruments, it is necessary to carry out actual research and select products that have passed the test of harsh environment, and not only to determine the purchase of instruments by the indicators of the manual, (especially the key instruments) to find at least three products that meet the requirements. First, consider quality, after-sales service, and put the price in the second place.
