Harorat o'tkazgichlari uchun ehtiyot choralari

The power supply of the temperature transmitter must not have spikes, otherwise it is easy to damage the transmitter. The calibration of the transmitter should be carried out 5 minutes after power on, and attention should be paid to the ambient temperature at that time. When measuring high temperatures (>100 daraja ), sensor kamerasini ulanish qutisidan yuqori harorat tufayli uzatuvchi yonib ketishining oldini olish uchun plomba materiallaridan foydalanish kerak. Kuchli shovqin holatlarida datchiklardan foydalanilganda, shovqinni oldini olish uchun korpus mahkam tuproqli bo'lishi kerak va quvvat va signal chiqishi F 10 ekranlangan kabel uzatmasidan foydalanishi kerak, germetik gaykani mahkamlash uchun mahkamlash kerak. Faqat RWB harorat uzatuvchisi 0-10mA chiqishiga ega, bu uch simli tizim va diapazon qiymatining 5% dan past. Transistorning o'chirilgan xarakteristikasi tufayli u chiziqli emas. Harorat o'tkazgichlarini har 6 oyda bir marta kalibrlash kerak. Agar DWB sxema cheklovlari tufayli chiziqli tuzatishni amalga oshira olmasa, uning chiziqliligini ta'minlash uchun ko'rsatmalarga muvofiq diapazonni tanlash yaxshidir.
