Bently Nevada 140471-02 3500 Mashinalarni himoyalash tizimida dinamik bosimni monitoring qilish uchun mo‘ljallangan kiritish/chiqarish moduli hisoblanadi. Modul yuqori haroratli bosim datchiklaridan keladigan signal kirishlarini qayta ishlab, signalni shartlaydi va ma’lumotlarni 3500/64M asosiy monitor platasiga uzatadi. Ichki terminatsiya simlari ulanishlariga ega bo‘lgan 140471-02 datchik signallarini yo‘naltiradi, datchiklarni quvvat bilan ta’minlaydi va tashqi boshqaruv tizimlari uchun proporsional +4 dan +20 mA gacha qayd signallarini chiqaradi.

Xususiyatlari

3 simli va 2 simli bosim datchigi kirishlari uchun bevosita ichki terminatsiya ulanishlari
Datchik quvvatini integratsiyalangan yo‘naltirish: 3 simli datchiklar uchun -24 VDC va 2 simli datchiklar uchun 22 VDC nominal kuchlanishda 3,3 mA tok manbaini ta’minlaydi
3500/64M dinamik bosim monitoriga 4 kanalli signal yo‘naltirishni qo‘llab-quvvatlash
Har bir kanal uchun 4 dan 20 mA gacha proporsional qayd chiqishlari uchun maxsus terminal ulanishlari
2 simli yoki 3 simli datchikning dala o‘tkazgichlari konfiguratsiyasini tanlash uchun sozlanadigan ichki jumperlar

Qo‘llanilishi

Gaz turbinasida yonish jarayonining dinamik bosimini monitoring qilish
Gidro turbinasidagi dinamik bosimni o‘lchash
Porshenli kompressor silindridagi dinamik bosimni monitoring qilish
Sanoat mashinalarini himoyalash va holatini monitoring qilish

O‘rnatish bo‘yicha ko‘rsatmalar

Ulashdan oldin har bir kanal jufti (CH1/CH2 va CH3/CH4) uchun ichki jumperlar holati ulangan o‘zgartkich turiga (2 simli yoki 3 simli) mos kelishini tekshiring.
Dala simlari tegishli ichki terminal bloki kolodkasiga (masalan, 8 kontaktli, 6 kontaktli yoki bosib kiritiladigan prujinali kolodkalarga) mahkam ulanganini ta’minlang.
Elektromagnit ekranlash samaradorligini saqlash uchun kabel ekranlarini to‘g‘ridan-to‘g‘ri belgilangan SHLD/SHIELD terminallariga ulang.
Modulni 3500 rafi orqa uyasiga, tegishli 3500/64M monitorining asosiy platasining bevosita orqasiga o‘rnating.
