The 990-05-70-02-01 Bu bitta modulga kontaktsiz yaqinlik zondi sensori drayveri va analog signal konditsioneri elektronikasini birlashtirgan, tok konturi orqali quvvatlanadigan tebranish transmitteri. U aylanuvchi mexanizmlardagi standart radial val tebranishini o‘lchaydi va 4 dan 20 mA gacha bo‘lgan uzluksiz tok konturi signalini bevosita PLC, DCS yoki SCADA tizimiga chiqaradi. Boshqaruvga to‘g‘ridan-to‘g‘ri ulanish arxitekturasi alohida maxsus monitoring stendida bo‘lish zaruratini bartaraf etadi. Uyurmali tok o‘lchovi prinsiplaridan foydalanib, transmitter valning dinamik harakatini mexanik yeyilmasdan monitoring qiladi va korxona operatsiyalari uchun ishonchli himoya ma’lumotlarini taqdim etadi.

Xususiyatlari

Integratsiyalangan drayver va signal konditsioneri konstruksiyasi panelda talab qilinadigan joyni kamaytiradi.
To‘g‘ridan-to‘g‘ri 4-20 mA chiqish standarti sanoat boshqaruv platformalariga muammosiz ulanadi.
Kontaktsiz uyurmali tok o‘lchovi mexanik ishqalanish va yeyilishni bartaraf etadi.
Old paneldagi qulay BNC ulagichi diagnostika uchun buferlangan xom tebranish signallarini uzatadi.
Qattiq holatli elektr zanjiri himoyasi ulanishdagi xatolar va kuchlanish sakrashlaridan himoyalaydi.
Og‘ir sanoat texnologik hududlariga o‘rnatish uchun ishlab chiqilgan, atrof-muhit ta’siriga chidamli mustahkam konstruksiya.

Qo‘llanilishi

Markazdan qochma havo kompressori tebranishini monitoring qilish.
Kichik sanoat ventilyatori va texnologik havo purkagichni himoyalash.
Sovitish minorasi ventilyatori mexanik himoya konturlari.
Sanoat markazdan qochma nasosi valini kuzatish.

O‘rnatish bo‘yicha ko‘rsatmalar

Mexanik o‘rnatish: Transmitterni himoyalangan dala korpusi ichidagi toza 35mm DIN-relsga mahkam o‘rnating.
Transduserni joylashtirish: Yaqinlik zondi va uzaytirgich kabelini mashinaning belgilangan podshipnik korpusiga o‘rnating. Ichki o‘zak shikastlanishining oldini olish uchun kabelning minimal bukilish radiusini 25.4 mm (1 in) saqlang.
Kabelni yo‘naltirish: Uzaytirgich kabelini transmitter joylashgan joygacha yo‘naltiring. Elektr shovqinini kamaytirish uchun zond kabellarini yuqori kuchlanishli elektr liniyalari yoki o‘zgaruvchan chastotali yuritma simlariga parallel yo‘naltirmang.
Koaksial ulanish: Zond uzaytirgich kabelini transmitter korpusining pastki qismida joylashgan koaksial ulagichga ulang.
Kontur simlari: 4-20mA kontur quvvat manbasini transmitter terminal blokiga ulang. Qutblanish to‘g‘ri saqlanganiga ishonch hosil qiling: 1-terminal (+) va 2-terminal (-). Dala simlarini ulashdan oldin quvvat manbasini uzing.
Ekranni yerga ulash: Kabel ekranlarini faqat boshqaruv xonasidagi asboblar yeriga to‘g‘ri ulang. Zararli yer konturlarining oldini olish uchun ekranni ikkala uchidan ham yerga ulamang.

FAQ

Ushbu maxsus transmitter bilan 5 metrlik kabel tizimidan foydalanishim mumkinmi?

Yo‘q. «70» opsiya kodi tizim uzunligini 7,0 metrga kalibrlashni belgilaydi. 5,0 metrlik kabel tizimidan foydalanish jiddiy kalibrlash va o‘lchash xatolariga olib keladi.

Old paneldagi BNC ulagichi nima uchun kerak?

U 200 mV/mil nominal masshtab koeffitsiyentiga ega xom, filtrlanmagan kuchlanish signalini ta’minlaydi. Bu texnik xizmat ko‘rsatish guruhlariga 4-20mA tok konturiga xalaqit bermagan holda, batafsil vibratsiya tahlili uchun ko‘chma ma’lumot to‘plagichlarni ulash imkonini beradi.

Ushbu transmitterga tashqi tok konturi quvvati kerakmi?

Ha. Bu tashqi 12 dan 35 VDC gacha quvvat manbaini talab qiladigan tok konturidan quvvatlanuvchi qurilma bo‘lib, odatda bu quvvat DCS yoki PLC analog kirish moduli tomonidan ta’minlanadi.
