imikhiqizo

I-Thermocouple Input Block inamapheya amathathu ahlukene okokufaka. Ama-Transformer ahlukanisa amandla futhi ama-optical couplers ahlinzeka ngokuhlukaniswa kwesignali. Ngepheya ngayinye yokokufaka: 1. Ngemva kokuhlunga, okokufaka kwesignali ngakunye kushintshwa ngokulandelana kube iamplifier evamile okukhiphayo kusetshenziswa kusiguquli se-voltage-to-frequency. Imvamisa yesiginali yokuphumayo ye-VFC isetshenziswa kukhawunta yefrikhwensi nge-coupler ebonakalayo. Imvamisa yokuphumayo ibalwa ngesikhathi sesango lama-millisecond angu-400, okuwukuphindaphinda okuvamile kwazo zonke izikhathi zefrikhwensi yemigqa evamile. Lokhu kunikeza ukwenqatshwa okukhulu kokuthathwa kwemvamisa yomugqa. 2. I-multiplexer ihlanganisa okunye okokufaka phakathi kwezikhathi zokufaka ezimbili eziyinhloko ze-thermocouple. Okunye okokufaka kuvela kuzinzwa ze-junction ezibandayo kanye nezinkomba zangaphakathi. Okokufaka okuhlanganayo okubandayo kuyalinganiswa futhi kugcinwe ukuze kunxeshezelwe kamuva amaphutha okulinganisa okokufaka kwe-thermocouple avamile. 3. Ukuze kutholwe futhi kulungiswe noma iyiphi inzuzo noma i-offset drift ku-amplifier noma i-VFC, ibhulokhi ithatha ukufundwa okusha kwamazinga ereferensi yangaphakathi alinganiswe ngokwefekthri phakathi nokusebenza. Lezi zilinganiso ezintsha ziqhathaniswa namanani ereferensi agcinwe vimba. 4. Iphrosesa iguqula inani lokushisa elibandayo lendawo ehlanganayo libe amandla kagesi njengoba kucaciswe i-NBS monograph yohlobo lwe-thermocouple olusetshenziswayo. La mandla kagesi abe esengezwa esilinganisweni se-thermocouple ngaphambi kokuguqulelwa kumayunithi ashisayo. Njengoba kungase kube khona umehluko omncane phakathi kokulinganisa izinga lokushisa lendawo ebandayo kanye nezinga lokushisa langempela lendawo ebandayo, ukulungiswa kwe-offset kungafakwa kusetshenziswa I-Hand-hold Monitor. Lokhu kususwa kungenxa yokuhluka ekuhlanganiseni komugqa wetheminali futhi izici zokulungiswa zigcinwa Ku-Terminal Assembly EEPROM.
