1. Lapho ingcindezi inyuka,ingcindezi transmitterAyikwazi ukuphuma: Kulokhu, isikhombimsebenzisi esibonakalayo kufanele sihlolwe ukuvuthwa komoya noma ukuqhekeka. Uma kuqinisekiswa ukuthi akukhona, indlela ye-wiring kufanele ihlolwe. Uma i-wiring ilungile, ukunikezwa kwamandla kufanele kuhlolwe futhi. Uma ukunikezwa kwamandla kujwayelekile, isikhundla se-zero se-sensor kufanele sihlolwe ngokuphuma, noma ukucindezela okulula kufanele kwenziwe ukuze ubone ukuthi umphumela wokukhipha. Uma kukhona ushintsho, kukhombisa ukuthi inzwa ayilimali. Uma kungekho shintsho, inzwa isivele ilimele. Ezinye izizathu zalesi simo nazo zingaba ukulimala kwensimbi noma ezinye izingqinamba kulo lonke uhlelo.
2. Ukukhishwa kwengcindezi yokudlulisela kwengcindezi akuguquki, kepha umphumela wokudluliselwa kwengcindezi ushintsha kungazelelwe ngemuva kokungeza ingcindezi, kanye nesikhundla se-zero sokudluliselwa kosizo lokucindezela akwazi ukubuya. Isizathu salo mkhuba kungenzeka ukuthi sibangelwa indandatho yokubopha yenzwa yengcindezelo yengculazi, esiye yahlangana kaninginingi ekusetshenzisweni kwamakhasimende ethu. Imvamisa, ngenxa yokucaciswa kwendandatho yokubopha uphawu (ithambile kakhulu noma inqwaba), lapho inzwa iqiniswa, indandatho yokubopha icindezelwe ku-inset yenzwa yengculazi ukuvimba inzwa. Lapho ingcindezi iphezulu, indandatho yokubopha uphawu iqhume ivuliwe, okwenza inzwa yokucindezela iguquke ngenxa yengcindezi. Lapho ingcindezi yehla futhi, indandatho yokubopha uphawu ibuyela esimweni sayo sokuqala ukuvimba indawo yokungena kwengcindezi, futhi ingcindezi esele ayinakukhishwa. Ngakho-ke, isikhundla se-zero se-sensor asikwazi ukwehliswa. Indlela engcono kakhulu yokuqeda lesi sizathu ukususa inzwa futhi uhlole ngqo uma isikhundla se-zero sijwayelekile. Uma kujwayelekile, buyisela indandatho yokubopha uphawu bese uzama futhi.
3. Kunezizathu eziningana zesiginali yokukhipha engazinzile ye-Transmitter: (1) Umthombo wengcindezi ngokwawo uyingcindezi engazinzile (2), ikhono lokulwa ne-wiring aliqinile (4), inzwa ye-sensor ngokwayo ayiqinile (4), inzwa ngokwayo ivevezela kakhulu (5), futhi inzwa inephutha
4. Izizathu ezingenzeka ze-Transmitter yengcindezi zinikwe amandla ngaphandle kokukhipha zifaka: (1) Ithuluzi ne-sensor elihloliwe
5. Ukuphambuka phakathi kwe-transmitter kanye ne-pointer Pressure Gauge kukhulu. Okokuqala, ukuphambuka kujwayelekile. Okwesibili, qinisekisa ububanzi obujwayelekile bokuphambuka. Indlela yokuqinisekisa ibanga elijwayelekile lephutha: Bala inani lephutha le-Gauge yengcindezi. Isibonelo, uhla lwengcindezi yegeji kungu-30Bar, ukunemba kungu-1.5%, kanye nesilinganiso esincane ngu-0.bar. Iphutha elijwayelekile yile: 30Bar * 1.5% + 0.2 * 0.5 (Iphutha elibonakalayo) = 0.55 Bar
6. Inani lephutha lokudluliselwa kwengcindezi. Isibonelo, uhla lwezinzwa zengcindezi lungama-20bar, ngokunemba okungu-0.5%, kanye nokunemba kwensimbi kungu-0.2%. Iphutha elijwayelekile lingu-20Bar * 0.5% + 20Bar * 0.2% = 0,18bar. Ibanga lephutha elingaba khona elingavela ngesikhathi sokuqhathanisa sonke kufanele lisuselwe ebangeni lephutha lemishini enenani elikhulu lephutha. Isibonelo esingenhla, inani lokuphambuka phakathi kwenzwa kanye ne-transmitter ngaphakathi kwe-0.55bar kungabhekwa njengokujwayelekile. Uma ukuphambuka kukhulu kakhulu, amathuluzi anemba okuphezulu (okungenani aphezulu kunama-gauges wengcindezi kanye nezinzwa) kufanele kusetshenziselwe inkomba.
7. Umthelela wesikhundla sokufaka sengcindezelo ehlukile yengcindezelo yokudluliselwa kokukhishwa kwe-zero Ngakho-ke, isimo sokushintsha kwe-zero esenzeka ngesikhathi sokufakwa kwe-Micro Ehlukile Yengcindezelo Transmitter yisimo esijwayelekile. Ngesikhathi sokufakwa, ukuqondiswa kwe-axial yengxenye enobuntu yengcindezi yomhambisi kuyoba nge-perpendicular kuya ekuqondisweni kwamandla adonsela phansi. Uma izimo zokufaka zilinganiselwe, isikhundla se-zero se-transmitter sizoshintshwa ngenani elijwayelekile ngemuva kokufakwa nokulungiswa.
