Purchase of weight scales

How to buy a high quality weight scale?∏±← This is a very inconvenient p®♦roblem for the purch ♣ase of weighing scales, the mλ♦¥"ain reason is that one of δ the sources of the problem is the i∞‍nstallation problem. The scale iε←>s actually a device that t¥δφ✘ransforms the quality signal into a measura£ ble electrical signal output. When ✔₩using a weighing scale, the first thing to consiφ£<"der is the actual working environment in whichβ±→< the weighing scale is lo"βcated, which is very important for the co₩ rrect selection of t♥¶he weighing scale. It is related to whether the ∞εweighing scale can work normally, its safetyββ↕Ω and service life, and even the reliab∑<δility and safety of the whole weighi₩&ng instrument.

Why can we say that the αδ ↑installation environment of weighin↑↑g scale occupies a major factorβ↔₽☆, we can consider from the followin&δg aspects. Firstly, the high temperature ¥€±÷environment causes the m÷Ω"↑elting of coating material<™, solder joint opening, and str∑•÷₽uctural change of stre≠★ss in elastic body. For the weighing scale wor←σ"'king in high temperature enviro ​nment, the high temperature resist$δ≠ant weighing scale is often used. In specialλ∏γ≠ cases, it must be equipped with heat i‌≤αnsulation, water cooling or air cool‍‌π$ing devices. The second is the influence of d∏​©ust and humidity on the short circuit o♦ ♥Ωf weight scales. Under this environment co<≠πndition, we should choose highly weighed∏‌÷γ scales.Different scales weigh d $ifferent ways of sealing, and≥∑♦ their closeness is quite different. Common sea¶≤λls are filled or coated α•with sealant, mechanical fastening seals for rubb≈≤σer pads, argon arc welding, plasma beam weldin≈ βg and vacuum nitrogen fα≈φilling seals. From the ₹<sealing effect, welding seal is better, fil±×↔ling and sealing sealant is poor. For weighing sc$≈≤↕ales working in clean and dry indoor en♥₩‌vironment, glue-coated weighing scales can be ★₩selected. For some weighing scπ§π×ales working in humid and dusty♣$ environment, hot-sleeve diaphrε ★φagm sealing or welding diaphragm seaφ≤ling and vacuum nitrogen filling weight scales™♥≥ should be selected.

The weighing scale working in the abov ♥e two environments needs strict requirements. ♥↔Of course, there are so‌↑ me environments which are also easy to£•™♦ contact. Considerations of corrosive environm"∞ent, strong electromagnetic field and flam₩₩≥εmability are all necessary to choose→γπδ weighing scale. Secondly, the number and scal€≠≈λe of weight scales are chosen. The $​≈←consideration of quantity is related to the way ♠ of use and the point of force. We need to co £∑nsider it according to different force poi​≈πnts and different weighing values∞α↕✘.

Use of weight scales

The selection of the number of weighing scaleΩ↑≠s is based on the use ​ ≠ of electronic weight and the number of poin₽∞←ts needed to support the weighing body (the numbe∞×r of supporting points sh‌'ould be determined according to the principle of ¥↑ ←overlapping the geometric center of g¶'​ravity and the actual center of gravit >y of the weighing body)‌≈♥. Generally speaking,$>¥♣ a few weighing scales are selected for se¥♦↓veral supporting points of the scale bodyε↓, but for some special weighing bodies such®<↓☆ as electronic hook scales, only one w₽¶☆eighing scale can be used. Some ele<×φ★ctromechanical scales should determine >​the number of weighing scales s‌‌elected according to the actual situation. Th​•±≥e size of the scale is mainl∞​y determined by the type of we​φ>ighing and the space of use. Ens★✘ure proper use, weighing safety ♣∏★and reliability; on the '♦γ₹other hand, we should consider σγλthe manufacturer's suggestions. The manufact×♥→urer usually stipulates the scope of a εpplication of weighing↑π‍ scale according to the force conditio≠₽n, performance index, daily use form, structur★₹£<e type and material of elastomer, for ex‌←¶ample, the aluminium cantilever beam weighing ↔≥"©scale is suitable for ☆‍λvaluation scale, platform sσσπ©cale, case scale, etc. The ® ☆>steel cantilever beam weighing scale is suitable✘∏♥₽ for hopper scale, electroni€∏c belt scale, etc. Th¶↕®δe steel bridge weighing s≥∞™cale is suitable for t¶∑∞rack scale, truck scale, c ∏≠rane scale, etc. The column weighing scale is su✔β↓¶itable for truck scale, dynamic tra ↑ck scale, large tonnage↔↕☆ hopper scale, etc. Instead of choosing♦≈ their own type, it is better to con↔£★sult the manufacturer's opinion to chooseγ& the weight scale.
