Bosim o'lchagich nima va u qanday ishlaydi?
Bosim o'lchagich - bu sanoatda suyuqlik yoki gazlardagi bosim darajasini o'lchash uchun ishlatiladigan o'lchov vositasi. Bu muhim vositadir, chunki u suyuqlik va gazlardagi bosim darajasini nazorat qilish va ularni kerakli chegaralarda saqlashga yordam beradi. Agar bosim oshib ketsa, u signal beradi. Xavfsizlik nuqtai nazaridan, bu juda muhim, chunki bosim darajasi oshib ketgan va uzoq vaqt davomida sezilmaydigan bo'lsa, asbob yoki mashina portlashi mumkin. Bu ishchilarni jarohatlashi va jihozlarga zarar etkazishi mumkin. Shuning uchun bosim o'lchagich zavodning umumiy xavfsizligi uchun juda muhimdir. Ushbu maqolada bosim o'lchagichning ishlash printsipi va boshqa tafsilotlari muhokama qilinadi.
Bosim o'lchagichning ishlash printsipi haqida gapirish
The working principle of the pressure gauge is based on Hooke's law, which states that the force required for a spring to expand or compress is linearly related to the distance of extension or compression. There are internal pressure and external pressure. Therefore, when pressure is applied to the surface of an object, the pressure on the inner side is greater due to the smaller area under pressure. Bourdon pressure gauges are widely used in all walks of life, and this is how they work.
Raqamli bosim o'lchagichlari hozir keng tarqalgan. Raqamli bosim o'lchagichlari uchun AC va shahar quvvat manbalari muhim rol o'ynaydi. Kommutatsiya davri yoki o'zgaruvchan tokni to'g'ridan-to'g'ri oqimga aylantirish. O'lchangan bosim sensorning diafragmasiga uzatiladi va sensor diafragma bosimni sezadi. Bunga asoslanib, kompyuter yoki smartfonga yetib borish uchun elektr signali ishlab chiqariladi. Ushbu hisoblagichlar kichik LCD displey bilan jihozlangan.
Bosim o'lchagichning boshqa muhim tafsilotlari
Pressure gauges range from basic measuring to fully automated, and can be connected to your smartphone to send alerts. The pressure sensor is an important part of the pressure gauge. There are many types of pressure gauges on the market, such as commercial pressure gauges, general service pressure gauges, stainless steel industrial pressure gauges, differential pressure gauges, double-sided pressure gauges, etc. With so many choices, it's obvious to be confused. Among various factors, the scale of the application must be one of the key considerations when selecting a pressure gauge for any process. These pressure gauges require regular maintenance and maintenance, because a pressure gauge that is out of service poses the same threat to the factory as there is no pressure gauge. Therefore, it is always better to have a small number of well-served meters in your factory. From an accuracy point of view, the installation and correct calibration of the pressure gauge are important aspects.
Ikki tomonlama bosim o'lchagichga- e'tibor qarating
Ikki tomonlama bosim o'lchagich-bosim o'lchagichlarning eng muhim turlaridan biridir. Ular kimyo, neft va gaz sanoatida keng qo'llaniladi. Quyida ikki tomonlama bosim o'lchagichlarning-ba'zi foydali xususiyatlari keltirilgan:
Ular asosan plastik korpusdan yasalgan va ogʻir{0}}bardoshli dizaynga ega.
Ular kimyoviy moddalarga, korroziyaga, abraziv materiallarga, yuqori haroratlarga va hokazolarga chidamli.
Ular juda aniq va bir nechta bosim diapazonlarida mos keladi.
Ularda Burdon trubkasi teflon diafragma bor.
Bu hisoblagichlarni toʻldirishingiz shart emas, chunki ular{0}}glitserin yoki optik silikon oʻlchagich suyuqligi bilan toʻldirilgan.
Ular polikarbonat linzalari, yuqori zarba qarshiligi va yorqin diapazonli yorliqli rangli displeylar bilan jihozlangan.
Ular ikki tomonlama shkalaga ega va siz PSI/KPA va PSI/BAR o'rtasida birlikni tanlashingiz mumkin.
Filtrni yoki sumkani almashtirish kerak bo'lganda ular signal mexanizmiga ega.
Bular hatto ko'rish muammoli joylarda ham qo'llaniladi. Siz uni ushbu hududlarda mashinalarga yoki kimyoviy nasoslarga o'rnatishingiz mumkin.
