Tavsif

The 990-05-70-02-05 aylanuvchi mexanizmlar ishlab chiqaruvchi original uskunalar ishlab chiqaruvchilari (OEM) uchun ishlab chiqilgan 2 simli, tok konturidan quvvatlanadigan tebranish uzatgichidir. U yaqinlik zondi drayveri (proximitor) va signalni qayta ishlash elektronikasining funksional imkoniyatlarini bitta ixcham dala qurilmasiga birlashtiradi. Uzatgich kontaktsiz yaqinlik transduseri tizimiga bevosita ulanib, dinamik radial tebranish yoki valning cho‘zilishini kuzatadi va xom siljish ma’lumotlarini mutanosib 4-20 mA analog tok chiqishiga aylantiradi. Ushbu uzluksiz tok konturi alohida monitor stendlari yoki maxsus proximitor modullarini qo‘shmasdan taqsimlangan boshqaruv tizimlari (DCS), dasturlashtiriladigan mantiqiy kontrollerlar (PLC) yoki SCADA tarmoqlariga bevosita ulanadi va shu sababli muhim mexanizmlar xavfsizlik konturlari uchun joyni tejaydigan yechim hisoblanadi.

O‘rnatish bo‘yicha ko‘rsatmalar

Mexanik devor o‘tkazgichni o‘rnatish: Berilgan devor o‘tkazgich vint teshiklaridan foydalanib, transmitter modulini korpus ichidagi tekis panel yuzasiga mahkam o‘rnating.
O‘zgartkichni sozlash: 3300 NSv yaqinlik zondini loyiha muhandislik ko‘rsatmalariga muvofiq nishon materialiga nisbatan o‘rnating va masofasini sozlang. Zond bilan transmitterning koaksial kirish porti orasiga 7.0 m uzaytirgich kabelini ulang.
Namlikdan himoyalash: Namlik kirishi va yerga ulash xatolarining oldini olish uchun zond va uzaytirgich kabelining koaksial ulanishlarini o‘z-o‘zidan birikuvchi silikon lenta bilan o‘rang.
Elektr konturi simlari: Qabul qiluvchi asbobdan keladigan 4-20 mA signal simlarini to‘g‘ri (+/-) qutblilikni saqlagan holda transmitter klemmasiga ulang. Maksimal 35 Vdc ta’minot chegarasidan oshirmang.
Shovqindan himoyalanish: Transmitter konturi simlarini va zond uzaytirgich kabellarini o‘zgaruvchan chastotali yuritma (VFD) chiqishlari, dvigatel ta’minot simlari yoki yuqori kuchlanishli AC elektr liniyalaridan alohida yo‘naltiring.
Kontur verifikatsiyasi: Kontur zanjirini quvvatlantiring va nazorat qilinayotgan val to‘liq harakatsiz bo‘lganda standart 4 mA boshlang‘ich chiqish signalini tekshiring.

FAQ

Ushbu transmitter konfiguratsiyasi uchun kabelning umumiy uzunligi qancha bo‘lishi kerak?

Ushbu transmitterga -70 tizim opsiyasi bilan belgilanganidek, zond va uzaytiruvchi kabelning jami uzunligi aynan 7,0 metr bo‘lishi kerak.

Muhandis val tebranishini tok chiqishidan bevosita qanday hisoblay oladi?

Konversiya formulasi: Tebranish (mils pp) = (halqa toki mA da - 4) * (5 mils / 16 mA).

Ushbu muayyan transmitterni standart 35 mm DIN-relsga bevosita o‘rnatish mumkinmi?

Yo‘q, ushbu muayyan -02 opsiyasi panelga o‘rnatish uchun bulkhead vintli konfiguratsiyaga ega. Unda -01 opsiyasidagi DIN-rels klipi mavjud emas.
