Ubushushu besiCwangciso soMgaqo-siseko woMsebenzi kunye nokuqwalaselwa kokukhetha

Zisebenza njani izinzwa ze-thermocouled

Xa kukho abaqhubi ababini abahlukeneyo kunye noopicontuctors A kunye ne-B ukwenza ilogo, kwaye ezi ziphelo zibini zidityaniswe, kwaye zibizwa ngokuba sisiphelo sesinye, kwaye siyinto eshushu, kwaye i-loop enye, ikwangoku, i-elektromotive ekhoyo I-Thertoelectrotive. Le nto yokuvelisa amandla okufana kwamandla ngenxa yokwahluka kubushushu ibizwa ngokuba sisiphumo se-witbeck. Kukho iziphumo ezimbini ezinxulumene ne-fackbeck: Okokuqala, xa kungena ngokuhamba kwezithuthi ezimbini, ubushushu bunokuthathwa okanye zikhutshiwe apha (kuxhomekeka khona isiphumo se-PLTIR; Okwesibini, xa uqukuqu ngoku ngomqhubi onesidima seqondo lobushushu, umqhubi wesifundo efumana okanye ekhuphe ubushushu (kuxhomekeke kwicala lobushushu), eyaziwa ngokuba yi-thomson. Ukudityaniswa kwabaqhubi ababini abahlukeneyo okanye aboyigoci babizwa ngokuba yi-thermocouple.

INDLELA YOKUZIPHATHA NGAYO

Ixabiso lokuphiliswa komqhubi oguqukayo noxinzelelo, kwaye iqondo lobushushu lento ukuba libalwe ngokulinganisa ixabiso lokuchasana. Ijensor eyenziwa yile mfundo ilusizi lobushushu, esetyenziselwa ikakhulu kubushushu kuluhlu lwamaqondo obushushu akwa--200-500 ° C. Umlinganiso. Isinyithi esicocekileyo sezona zinto ziphambili zokuchasana ne-thermal, kwaye umxholo wokuphikisana kwe-thermal kufuneka ube neempawu zilandelayo:

.

.

(3) Izinto ezibonakalayo zinobuhle obuhle nobugcisa, kwaye ixabiso liphantsi.

(4) Iipropathi zekhemikhali kunye nezomzimba ziyazinza ngaphakathi kwinqanaba lokulinganisa lobushushu.

Okwangoku, iPlatinam kunye nobhedu ngowona usetyenziswa kakhulu kwishishini, kwaye zenziwe ukuba kubushushu obuqhelekileyo obulinganisa ukumelana nokungaxhathisi.

Ukuqwalaselwa xa ukhetha i-sensor yobushushu

1. Nokuba iimeko zokusingqongileyo zento ecikishelweyo zinomonakalo wokulinganisa ubushushu.

2. Ingaba iqondo lomsindo lemilinganiselo kufuneka irekhodwe, iyothuswe kwaye ilawulwe ngokuzenzekelayo, nokuba kufuneka ilinganiswe kwaye idluliselwe kude. I-3800 100

3. Kwimeko apho iqondo lobushushu litshintsha kunye nexesha, nokuba i-LIG yendawo yokulinganisa yobushushu inokuhlangabezana neemfuno zokulinganisa ubushushu.

4. Ubungakanani kunye nokuchaneka koluhlu lwemilinganiselo yobushushu yobushushu.

5. Ingaba ubungakanani bento yokulinganisa yobushushu bulungile.

6. Ixabiso liyaqinisekiswa nokuba lilungele ukusetyenziswa.

Ungaziphepha njani iimpazamo

Xa ufaka kwaye usebenzisa i-sensor yobushushu, ezi mpazamo zilandelayo kufuneka zithintelwe ukuqinisekisa eyona nto ibalulekileyo.

1. Iimpazamo ezibangelwa kukufakelwa okungafanelekanga

Umzekelo, indawo yokufakelwa kunye nokufakwa kobunzulu be-thermocouple akunakubonakalisa ubushushu bemithamo yesixhobo. Ngamanye amagama, i-thermocouple ayifakwanga kufutshane nomnyango nokufudumeza, kwaye ubunzulu bokufakelwa bunokuba nobuncinci buyi-8 ukuya kwi-10 ububanzi betyhubhu yokhuseleko.

2. Impazamo yokuxhathisa i-thermal

Xa iqondo lobushushu liphezulu, ukuba kukho umaleko we-ash yelahleko kwityhubhu yokukhusela kwaye uthuli luqhotyoshelwe kuyo, ukuxhathisa i-shirmal kuya kukhusela kwaye kuthintele indlela yokufumana ubushushu. Ngeli xesha, amaqondo obonisa amaqondo obonisa amaqondo obonisa amaqondo obushushu asezantsi kunexabiso lokwenyani lobushushu obulinganiselweyo. Ke ngoko, ngaphandle kwetyhubhu yokhuseleko lwe-thermocouple kufuneka igcinwe icocekile ukunciphisa iimpazamo.

I-3. Iimpazamo ezibangelwa kukuvalelwa kakubi

Ukuba i-thermocouple i-insulin, i-dirt emdaka kakhulu okanye ityiwa yetyuwa kwityhubhu yoKhuselo kunye neBhodi yomzobo ecikizekileyo iya kukhokelela kwi-thermouple kunye ne-londlity yodonga, elingayi kwenza kuphela ukuphazamiseka. Impazamo ebangelwa kuku ngamanye amaxesha ifikelela kwi-baidsu.

4. Iimpazamo ezingeniswe yi-thermal ithortia

Le mpembelelo ibizelwe ngokukodwa xa usenza imilinganiselo ekhawulezayo kuba i-Intertia ye-thermal ye-thermocouple ibangela ukuba ixabiso lemitha libekwe kwi-lag emva kotshintsho kwiqondo lobushushu lilinganiswe. Ke ngoko, i-thermocouple ye-elektroni ye-thermal ye-thermal kwaye idayimitha encinci yetyhubhu yokhuseleko kufuneka isetyenziswe kangangoko kunokwenzeka. Xa imeko yobushushu imvume, ityhubhu yokukhusela inokuthi isuswe. Ngenxa yeleg yokulinganisa, i-illivest yobutshijolo wobushushu obufunyanwa yiThermocouple incinci kunelo cussis ye-wotland. Inqanaba le-Lag lokulinganisa, elincinci elincinci lokutshintsha kwe-thermocouple kunye nokukhulula umahluko kubushushu bothando.
