Ukufakwa
Lesi sigaba sichaza izinqubo zokukhweza i-T2A endaweni yokuqapha nokuxhuma i-T2A ngocingo.
Ukufaka i-T2A
1. Cabangela okulandelayo uma ukhetha indawo yokukhweza. · Khetha isayithi lapho i-T2A ingeke ishaywe noma iphazamiseke. Qiniseka ukuthi kunendawo eyanele yokwenza izinqubo zokuqalisa, ukulungisa, kanye nokulinganisa. · Khetha indawo emele indawo yokuqapha nalapho igesi eqondiwe ingase inqwabelane noma lapho okungenzeka ukuthi ivuze khona. I-T2A akufanele ifakwe eduze nendawo yokungena, indawo yokungenisa umoya, noma indawo yokukhipha umoya. · Inzwa kumele ikhombe phansi. • Gwema ukufaka i-T2A endaweni lapho izinhlayiya ezihamba emoyeni zingase zimboze noma zimboze inzwa.
QAPHELA: Le mihlahlandlela ihloselwe KUPHELA njengomyalelo ojwayelekile wokubekwa kwe-T2A. Lolu lwazi AKUMELE lusebenze njengohlu oluphelele lapho kucutshungulwa wonke amapharamitha angaba khona wendawo efanele yeyunithi. KUNIKEZWA KAKHULU ukuthi inkampani yangaphandle Certified Industrial Hygienist, noma omunye Uchwepheshe Oqinisekisiwe Wokuphepha, enze inhlolovo yesayithi futhi achaze indawo nenani lamadivayisi okuthola ulwazi okufanele afakwe KUNJALO ukufakwa kwaSONKE isayithi.
2. Khetha indawo yokukhweza kanye ne-hardware yokufaka. Ukukhweza esakhiweni sikakhonkolo noma sensimbi kunconywa ukunciphisa ukudlidliza nomswakama. Sebenzisa isikulufu esiphezulu esingu-1/4″-20 noma esingu-1/4″ ubukhulu, amawasha ayisicaba, izinto zeBanga lesi-5, nokuvikela ukugqwala okufana nopende, uthayela, noma i-zinc plating.

I-RKI incoma ukuthi okokusebenza kwethu kukalwe nge-MINIMUM njalo ezinsukwini ezingama-90, futhi yeluleke NGOKUQINILE ukuthi ukulinganisa kwenziwe njalo ezinsukwini ezingama-30. Ngaphandle kokwazi uhlelo oluthile, indawo yokuhlanganisa inzwa, ukuchayeka kwegesi nezinye izici, inkampani incoma ukulinganisa kwanyanga zonke kucatshangwa ukuthi akukho monakalo noma umonakalo ongaba khona owenzekile kunzwa nokuthi akuzange kube khona amandla okukhipha.tage ekuhlanganiseni kwenzwa. Uma kwenzekile umonakalo noma amandla anikezwe inzwa eshintshile, ukulinganisa kufanele kuqedwe ngokushesha.
Ukugcinwa okuhleliwe kufanele kufake uziro nokulinganisa kwenzwa (bheka ikhasi 37) kanye nokuhlolwa kwe-alamu (bheka ikhasi 25).
Ikhanda lenzwa kufanele ligcinwe lingenazo izinhlayiya ezihamba emoyeni, ukungcola, udaka, isicabucabu webs, izimbungulu nezinambuzane, kanye/noma noma iyiphi enye imfucumfucu engase imboze noma imboze inzwa. Ukugcina ikhanda lenzwa licacile kuma-athikili angaphandle kuzovumela ukusebenza kahle kwedivayisi. Ukuhlola okufushane phakathi nokulungiswa okuhleliwe kufanele kwanele, kodwa kuye ngokuthi indawo nendawo lapho iyunithi ifakwe khona, ukuhlolwa okuvamile kungase kuqinisekiswe.
I-T2A ingase ithikamezeke kabi ukuchayeka ezintweni ezithile ezihamba emoyeni. Ukulahlekelwa ukuzwela noma ukugqwala kungase kwenzeke kancane kancane, uma izinto ezinjalo zikhona ekugxilweni okwanele. Ukusebenza kocingo kungase kuphazamiseke ngesikhathi sokusebenza lapho kukhona izinto ezingabangela ukugqwala ekucwecweni kwegolide. Ukugxila okuqhubekayo kanye nokuphezulu kwamagesi abolayo kungase kube nomthelela wesikhathi eside omubi empilweni yesevisi yomkhiqizo. Ukuba khona kwezinto ezinjalo endaweni akuvimbeli ukusetshenziswa kwalesi sisetshenziswa, kodwa amathuba okuba kufinyelelwe isikhathi sokuphila se-sensor element, ngenxa yalokho, kufanele kuqashelwe. Ukusetshenziswa kwe-T2A kulezi zindawo kungase kudinge ukulungiswa okuhleliwe okuvame kakhulu ukuze kuqinisekiswe ukusebenza kwesistimu okuphephile nokuthembekile.

Ukulinganisa
Ukulinganisa kuyinqubo yokuhlola nokulungisa ukunemba nokunemba kwempahla yokulinganisa. Nakuba i-RKI ilinganisa zonke izisetshenziswa efekthri, ukuze kube nokunemba okungcono kakhulu, umtshina KUFANELE ulinganiswe endaweni ofakwe kuyo.
Ukulinganisa Imvamisa
Ukulinganisa kufanele kwenziwe NJALO ezinsukwini ezingamashumi amathathu (30). Izinsuku kusukela ekulinganisweni kokugcina AKUMELE zidlule izinsuku ezingamashumi ayisishiyagalolunye (90). I-RKI incoma ukuthi ulinganise idivayisi yakho njalo ukuze uqinisekise ukusebenza okufanele nendawo yokusebenza ephephile.
Izinto zokwakha
· Isilawuli sokugeleza esingaguquki esingu-0.5 LPM esine-knob neshubhu yokulinganisa
ISEXWAYISO: Uma ilinganisa nge-Cl2 noma i-HCl, isilawuli kufanele sinikezelwe ukusetshenziswa naleyo gesi kuphela. Ungasisebenzisi leso silawuli esizinikele kunoma imaphi amanye amagesi, ikakhulukazi i-H2S.
· inkomishi yokulinganisa
· Isilinda somoya esiyiziro (uma singekho endaweni yomoya omusha)
· Isilinda sokulinganisa noma ijeneretha yegesi (Kuzinzwa ze-O2, i-RKI incoma ukugxiliswa kuka-10-18% O2. Kuzo zonke ezinye izinzwa, i-RKI incoma ukusebenzisa u-50% yenani eliphelele lesikali segesi yakho etholiwe.)
QAPHELA: Amanye amagesi atholiwe asebenzisa amagesi e-surrogate ukuze alinganise. Amagesi atholiwe adinga igesi yokuthatha indawo yokulingana ukuze alinganiswe abhalwe ngezansi. Uma usebenzisa igesi yokungena esikhundleni ukuze ulinganise, leyo gesi yokungena esikhundleni ephindwe ngento ebhalwe ngezansi kufanele ilingane no-50% wesikali esigcwele segesi etholiwe.

Isithasiselo A: Isignali engu-4-20 mA
Lesi sithasiselo siyisingeniso kuphela. Ulwazi kufanele lusebenze njengesifinyezo esifushaneview ye-4-20 mA yobubanzi besiginali yeluphu yamanje futhi akufanele ithathwe njengereferensi ephelele yokusetshenziswa okufanele noma ukusetshenziswa.
Amazinga embonini aphathelene namasiginali weluphu yamanje engu-4-20 mA nezinye izici ze-electronics kucatshangwa ukuthi zaziwa uchwepheshe. Ukuze uthole uxhumano olufanele kusilawuli noma Isilawuli Sengqondo Ehlelekayo (PLC), bheka imanuwali eqondile yomkhiqizi noma iziqondiso zaleyo divayisi.
Kuphelileview
Uma usebenzisa amadivaysi esignali okukhiphayo anentambo engu-4-20 mA, i-4-20 mA ichaza ububanzi besignali ye-loop yamanje, ene-4 mA emele isiphetho esiphansi kakhulu sobubanzi kanye no-20 mA esiphezulu. Ubudlelwano phakathi kweluphu yamanje kanye nenani legesi buwumugqa. Ukwengeza, i-T2A isebenzisa amanani angaphansi kuka-4 mA ukukhombisa izimo ezikhethekile zesimo, njengoba kuboniswe ngezansi:

I-4 mA ivumela isilawuli/PLC esamukelayo ukuthi sihlukanise phakathi kwesignali enguziro, intambo ephukile, noma ithuluzi elingasabeli. Izinzuzo zesimiso se-4-20 mA ukuthi: izinga lemboni, izindleko eziphansi zokuqalisa, lingenqaba ezinye izinhlobo zomsindo kagesi, futhi isignali ayishintshi inani elizungeze "iluphu" (ngokuphambene nevolthitage). I-advan eyisihluthulelotagI-e yeluphu yamanje ukuthi ukunemba kwesiginali akuthintwa ivolumu engaba khonatage yehlisa izintambo ezixhumene. Ngisho nokumelana okubalulekile emgqeni, iluphu yamanje i-T2A izogcina ukusebenza kwamanje okufanelekile kwedivayisi, kuze kufike ku-voltage yayo ephezulu.tage ikhono.
Yileveli yamanje eyodwa kuphela engaba khona noma kunini. Idivayisi ngayinye esebenza ngesignali yeluphu yamanje engu-4-20 mA kufanele ifakwe intambo ngokuqondile kusilawuli. Amayunithi anezintambo ekucushweni kweketango le-daisy kusignali yamanje yeluphu engu-4-20 mA ngeke athumele ngokufanelekile ukuxhumana kwedatha kusilawuli.
Izibalo
I(4-20) = Yamanje yeluphu, ikalwa ngevelu ye-mA = ppm (noma %) yesilinganiso sokuhlushwa kwegesi = isikali esigcwele senzwa

Ukulinganisa Okwamanje
Uma inani elilinganisiwe lingu-0 mA, khona-ke: izintambo ze-loop ziphukile, umhlangano wezinzwa awunikezwa amandla, umhlangano wezinzwa awusebenzi kahle, noma isilawuli singasebenzi. I-digital multi-meter (DMM), noma imitha yamanje, ingasetshenziswa ngokuhambisana nesilawuli kanye/noma ukuhlola isignali yeluphu yamanje engu-4-20 mA. Ukuze ulinganise i-current, beka ama-probe imitha ngokuhambisana neluphu yamanje.
