Amaphutha Amane Avamile Wenzwa Yokucindezela

1. Izinkinga zokuvala indandatho ye-pressure transmitter

Ngemuva kokucindezela kokuqala, ukuphuma kwe-transmitter akuzange kushintshe, futhi ukuphuma kwe-transmitter kwashintsha ngokuzumayo, futhi isikhundla se-zero se-transmitter asikwazanga ukubuyela emuva ngemva kokukhululeka kwengcindezi, okungenzeka ukuthi inkinga yendandatho yokuvala uphawu. inzwa yokucindezela.Isimo esivamile siwukuthi ngenxa yokucaciswa kwendandatho yokubeka uphawu, indandatho yokuvala icindezelekile ekungeneni kokucindezela kwenzwa ngemva kokuba inzwa iqinisiwe, ngaleyo ndlela ivimbele inzwa.Uma ucindezelwa, i-pressure medium ayikwazi ukungena, kodwa lapho ingcindezi iphezulu, indandatho yokuvala ivele iqhume, futhi inzwa yokucindezela ishintsha ngaphansi kwengcindezi.Indlela engcono kakhulu yokuqeda leli phutha ukukhipha inzwa futhi uhlole ngokuqondile ukuthi indawo ye-zero ijwayelekile yini.Uma indawo eyiziro ijwayelekile, buyisela iringi yokuvala bese uzama futhi.

2, ingcindezi ingakhuphuka, kepha okukhiphayo kwe-transmitter akukwazi ukuvuka.

Kulokhu, kufanele siqale sihlole ukuthi isixhumi esibonakalayo sokucindezela siyavuza noma sivinjiwe.Uma kuqinisekiswa, kufanele sihlole ukuthi imodi yezintambo ayilungile yini futhi sihlole ukunikezwa kwamandla.Uma ukunikezwa kwamandla kujwayelekile, kufanele sivele sikucindezele ukuze sibone ukuthi okukhiphayo kushintshile yini noma ukuthi indawo eyiziro yenzwa inokukhiphayo.Uma ingakashintshi, inzwa ilimele.Uma kungenjalo, inkinga yokulimala kwensimbi noma ezinye izixhumanisi zesistimu yonke.

3. Ukuchezuka phakathi kwe-transmitter kanye ne-pointer pressure gauge kukhulu.

Lokhu kuchezuka kuvamile, vele uqinisekise ububanzi bokuchezuka okuvamile;Iphutha lokugcina elenzeka kalula ithonya lendawo yokufaka yesidlulisi somfutho omncane ohlukanisayo ekuphumeni kweqanda.Ngenxa yobubanzi bayo obuncane bokulinganisa, izakhi zokuzwa ku-micro differential pressure transmitter zizothinta ukuphuma kwesidlulisi somfutho we-micro differential.Ngesikhathi sokufakwa, ingxenye ezwela ingcindezi yesidluliseli kufanele ibe ngama-axially degrees 90 perpendicular to gravity direction.Ngemva kokufaka nokulungiswa, khumbula ukulungisa indawo eyiziro yesidluliseli enanini elijwayelekile.

4. Isignali yokuphumayo yesidluliseli ayizinzile.

Lolu hlobo lwephutha lungabangelwa nakanjani umthombo wengcindezi.Umthombo wengcindezi ngokwawo uyingcindezi engazinzile.Kungenzeka ukuthi ikhono lokulwa nokuphazamiseka kwensimbi noma inzwa yokucindezela alinamandla, inzwa ngokwayo idlidliza kabi noma inzwa yonakalisiwe.
