Purchasing a weighing (electronic balance) product involves a total comparison of range and cost performance. Introduced some of the major issues to consider when purchasing scales (electronic balances).
When purchasing scales (electronic balances), there are several important criteria that can help you find the product that suits your needs. Usually the price is considered to be the decision point, but in order to obtain the maximum utility of the scale, you should consider the total value that the scale brings to your operation. If scales are a key issue for your business's efficiency and profitability, especially if scales are used to make or package products, low-cost instruments may cause more expensive losses in the long run.
One: The main standard for measuring range is the total weight of the object you want to weigh. A common mistake is to buy a weighing scale (electronic balance) with the same maximum weight as your usual weighing item. Although this may seem to be the right choice to help you buy a cheaper scale. It is important to remember a few technical specifications regarding the maximum range of the scale (electronic balance). A weighing instrument is rated at 100 pounds to add extra weight without damaging the scale. Ohaus products usually provide an overload level of 150% so that a 100-kilometre weighing instrument can handle a load of 150 kg. Exceeding this load may cause damage to the weighing equipment. What's more important is how to add weight to the scale. Some operations habitually throw objects or bags on the scale, which increases the force on the scale (also called dynamic load). Therefore, the same 100-kilometre weighing instrument can handle 90 kg load normally. If the same load falls from 5 feet, it may damage the weighing instrument. To ensure that the instrument is able to withstand the load is to purchase the instrument's maximum range is to weigh twice the weight of the object, so the 100 kg scale instrument is best to handle 50 kg load, rather than 60 kg scale instrument. A larger scale may initially cost more, but it is more suitable for your business needs.
Two: The weighing unit Another question to consider is which weighing unit does your operation use? Pounds, kilograms or ounces? According to your weighing object, the weighing unit used is also different:
Chang Heng system - lbs, ounces, tons, Kling and other metric - kilograms, grams, milligrams, metric tons of jewelry - Kline, Bennett (dwt), ounce (ozt), carat (ct) and other custom Weighing units In some cases, the weighing unit will be determined by legal regulations, and in others depending on your operational needs. Do you need to change the unit quickly or you only need to use one unit? When buying scales (electronic balances), it is very important to make sure that you understand the problem and purchase a scale that is right for your operation. Shanghai Jiashi Electronic Technology Co., Ltd. produces moisture analyzer and infrared moisture meter.
Three: Readability The other major factor is the readability of the scale (electronic balance) or how accurate the scale is. The readability of weighing instruments is often confused with the accuracy of weighing instruments (the accuracy of weighing instruments is the specific combination of weighing instruments, the setting method of weighing instruments, the use of weighing instruments, and the maintenance of weighing instruments). Many heavy-duty scales require only 0.1 grams of readability, while scales used on QA/QC (Quality Assurance/Quality Control) production lines may require a precision of 1 gram.
The intrinsic requirement of this question is the degree to which the reliability of the weight reading must be achieved. This may be regulated by law and affected by objects being weighed. The general rule of thumb is to buy a scale (electronic balance) with a precision that is ten times the accuracy you need (for example, if you need 1 g of readability, buy a scale that reads 0.1 g), or install approved/ Certified scales. If the weighing process is legally approved or certified, the scale must meet the legal standards for the reliability of the readability of the instrument. Even if your operation does not have this legal requirement, the use of approved/certified instruments will ensure a higher level of performance.
IV: Dimensions, Shapes, and Movements of Objects Objects that are weighed on most weighing scales (electronic balances) do not require special consideration, but your process may require additional functions of the scale to accurately measure. Is the size of the object too large, such as transport boxes, masking the display? Is the object moving, such as livestock, or the environment moving the object, such as a conveyor belt? Is the object round, and does it require you to box the product? Accurate understanding of what objects are being weighed is a key consideration.
Five: Mode/Software Once you have decided on the range and readability required, the next step is to decide what mode or software is required for the scale (electronic balance) that is right for your application. Most scales are used for direct weighing and may have some additional filtering functions to reduce environmental issues such as vibration. The most common weighing applications are:
Parts Parts Checkweighing Quantitative Percentage Weighing Dynamics Weighing Display Maintenance Data Accumulation/Summation Statistics Output Retail Price Calculation Traceability to Trade GMP or GLP When purchasing scales (electronic balances), decide if the scale has more than one application , and ensure that the actual workings of the scale (electronic balance) are suitable for your operation. Many scales (electronic balances) provide part-pieces, for example, but each scale (electronic balance) operates differently and may provide software to increase your part accuracy, all of which will affect the accuracy of your piece-rate in your daily business operations. Sex. When purchasing scales, local dealers can help you choose the scales that are right for your application and help set up the scales properly.
VI: Another problem with the environment is the overall environment in which you use scales (electronic balances). Almost all weighing instruments (electronic balances) work well in a laboratory environment, but scales (electronic balances) also have certain characteristics that can be used in harsh industrial environments or outdoors. The general specification of industrial scales is NEMA or IP rating, which tells you that the scale can resist the performance of dust, dirt, water, and other materials processed into the scale. Above this level, scales with IP65 or NEMA 4 or higher can be cleaned and resist the penetration of dust and water.
In addition to waterproofing, instruments used in food processing and catering services require additional approvals or certifications. NSF (National Science Foundation) provides numerous food safety standards and provides approval/certification for catering equipment. Moreover, weighing instruments can also be approved for use in food processing applications through USDA-AMS and often require equipment to support HACCP food safety systems. Knowing which food safety standards to implement is critical to ensuring that you have the right scale for your operation.
Seven: Temperature Another environmental factor is the temperature range, which is very important because the materials used for weighing probe production in weighing instruments (electronic balances) may be affected by the ambient temperature and the effects of rapid temperature changes. In addition to ensuring that the scale (electronic balance) is equal to the ambient temperature, most applications do not require special consideration, but if your scale is to be used in harsh environments, consult your local dealer to ensure that you purchase a scale suitable for the specific application. .
Eight: Connectivity Many situations require connectivity to computer systems and printers, which can provide traceability and process control. Most provide RS232 ports for connection to a printer or computer, but many scales (electronic balances) have USB, RS485/422, or other standard options. If your application requires connectivity or printing, choose the right scale. Usually your local dealer can integrate scales (electronic balances) into your production process or as a consultant to help you get the most out of your instrument investment.
Nine: After-Sales Support As with any other device, quality assurance requires an understanding of how many manufacturers provide their products with quality assurance. Most manufacturers will provide a quality guarantee for their product design defects or manufacturing defects for a certain period of time, although these issues will occur relatively early in the purchase period. Some manufacturers provide longer-term quality guarantees, and some provide shorter warranty periods, but in most cases the quality guarantees do not include improper use and accidental damage, or normal wear and tear.
As important as quality assurance is the technical support provided by the manufacturer. Is there information available online for easy access? Can you quickly download a new manual? Is there additional information on how to use the product, such as a quick start guide? Is there a dedicated technical support to contact by phone or online chat?
It is also important that you need the dealer to provide you with much support. Do you need a dealer to help you set up the scale and calibrate the scale for the best accuracy? Can they help you integrate scales into the production process? Can they provide regular calibration? Can dealers get repair spare parts easily? Are dealers an authorized dealer, or are they reselling products they purchased through another dealer?
Conclusion There are many factors to consider when purchasing (electronic balances), especially if your business depends on scales (electronic balances) to achieve profitability. As with any device, the value of a product, not its price, will determine whether it is a good investment. Please be sure to carefully consider your needs and the capabilities of the scale and you will be able to make the right choice.
Combined Flow Closed Cooling Tower
Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.
1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.
2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.
