Ubuyobozi buhebuje bwo Guhitamo Ikwirakwizwa rya Silicon
Muburyo bwinshi bwohereza imiyoboro-harimo ceramic, capacitive, na monocrystalline silicon variants - ikwirakwizwa rya silikoni ikwirakwizwa ryabaye igisubizo cyakoreshejwe muburyo bwo gupima inganda.
Kuva kuri peteroli na gaze kugeza gutunganya imiti, kubyara ibyuma, kubyaza ingufu amashanyarazi, no kubungabunga ibidukikije, ibyohereza ubutumwa bitanga igenzura ryizewe kandi ryukuri kurwego rwumuvuduko wikigereranyo, umuvuduko wuzuye, hamwe na vacuum.
Niki Ikwirakwizwa rya Silicon Yumuvuduko?
Ikoranabuhanga ryatangiye hagati mu myaka ya za 90 rwagati ubwo NovaSensor (USA) yatangizaga diaphragms ya silicon yakozwe na mikorobe ikomatanya ikirahure. Iri terambere ryaremye ibyuma byoroheje, byukuri-byukuri hamwe nibisubirwamo bidasanzwe kandi birwanya ruswa.
Ihame ry'imikorere
- Umuvuduko wibikorwa unyura muri diafragma yitaruye hamwe namavuta ya silicone kuri diaphragm ya silicon
- Umuvuduko werekana (ibidukikije cyangwa vacuum) ukoreshwa kuruhande
- Gutandukana kubisubizo bigaragazwa nikiraro cya Wheatstone yikigereranyo, gihindura igitutu mukimenyetso cyamashanyarazi
Ibipimo byingenzi byo gutoranya
1. Gupima Hagati Hagati
Ibikoresho bya sensor bigomba guhuza imiti nubumubiri byimikorere yawe:
- Ibishushanyo bisanzwe bikoresha 316L ibyuma bitagira umuyonga diaphragms kubisabwa byinshi
- Kubishobora kwangirika cyangwa korohereza ibintu, vuga flux diaphragm yohereza
- Ibyiciro-byokurya biboneka kubikoresho bya farumasi n'ibinyobwa
- Itangazamakuru ryinshi cyane (slurry, mud, asfalt) risaba ibishushanyo mbonera bya diaphragm bidafite umwobo
2. Guhitamo Urwego
Ibiboneka biboneka kuva kuri -0.1 MPa kugeza kuri MPa 60. Buri gihe hitamo intera iri hejuru ya 20-30% kurenza umuvuduko wawe wo gukora kugirango wirinde kurenza urugero.
Agasanduku k'ingutu
| Igice | Agaciro kangana |
|---|---|
| 1 MPa | 10 bar / 1000 kPa / 145 psi |
| 1 bar | 14.5 psi / 100 kPa / 750 mmHg |
Gauge vs Umuvuduko udasanzwe:Umuvuduko wa gauge werekana umuvuduko wibidukikije (zeru ihwanye nikirere), mugihe igitutu cyuzuye cyerekana vacuum. Kubisabwa murwego rwo hejuru, koresha ibyuma bifata ibyuma byerekana ibyuma kugirango uhindure ikirere cyaho.
Ibitekerezo bidasanzwe byo gusaba
Igipimo cya gaz ya Amoniya
Kugaragaza diaphragm zometseho zahabu cyangwa impuzu zihariye zo kurwanya ruswa kugirango wirinde kwangirika kwa serivisi muri ammonia. Menya neza ko amazu yimura yujuje ibyiciro bya NEMA 4X cyangwa IP66 kugirango ushyire hanze.
Kwishyiriraho Agace
Kubidukikije byaka cyangwa biturika:
- Saba amavuta ya fluor (FC-40) aho kuzuza amavuta asanzwe ya silicone
- Kugenzura ibyemezo byumutekano imbere (Ex ia) cyangwa flameproof (Ex d) porogaramu
- Menya neza ko ushyiraho inzitizi hamwe na bariyeri kuri IEC 60079
Umwanzuro
Imiyoboro ya silicon itandukanya itanga uburinganire bwiza, burambye, kandi buhindagurika mubikorwa byinganda. Guhitamo neza - uhereye kubitangazamakuru bihuza isuzumabumenyi kugeza ibisohoka byerekana ibimenyetso - byemeza ibipimo byukuri kandi byizewe igihe kirekire.
Haba kugenzura imirongo yumuvuduko mwinshi, kugenzura imiti yimiti, cyangwa kugenzura neza amoniya, iboneza ryogukwirakwiza neza byongera imikorere yumutekano ndetse nibikorwa byumutekano.
