Kungani ama-thermocoumpules abaluleke kakhulu ekulinganiseni izinga lesimanje?

Izihloko zezindaba eziphezulu: Izitayela zamanje kubuchwepheshe be-therkocouple

Ukuhlala phambili ekulinganisweni kwezimboni kudinga ukuhambisana nentuthuko yakamuva kuyotherkocoupleubuchwepheshe. Nazi izihloko eziseshelwe kakhulu ezibonisa ukugxila kwemboni yamanje:

Lezi zihloko zigqamisa amakhono aqhubekayo akhulisa amakhono ama-thermocoumple - kusuka ekulinganiseni izinga lokushisa ngokweqile ekuxhumaneni okuhle - kuqinisa indima yabo ebalulekile ezinhlelweni zesimanje zezimboni.

Ukuqonda Thermocouples: Isayensi ngemuva kwenzwa

Umgomo Wokusebenza
Emgogodleni wabo, ama-thermocoumple asebenza emthethweni we-Seebeck - into etholwa ngo-1821 lapho izinsimbi ezimbili ezingafani zihlanganiswe khona ezimisweni ezimbili zikhiqiza indlela yokulinganisa umehluko wokushisa phakathi kwazo. Lapho ukuhlangana okukodwa (i- "Hot Junction") kuvezwa emazingeni okushisa alinganiswa kanti omunye ("i-condlet junction") kuhlala endaweni yokushisa eyaziwayo, i-voltage ephumela ingaguqulwa ibe ngokufundwa kwamazinga okushisa okunembile.
Lo mklamo olula kodwa omuhle kakhulu uqeda isidingo semithombo yamandla yangaphandle, okwenza ama-thermocoumples athembekile ngezindawo ezikude noma eziyingozi. Ngokungafani nezinzwa ezisekelwe ekumelaneni (ama-RTDs), ukuqina kwazo ezimweni ezimbi kakhulu kuvela ezingxenyeni ezihamba kancane ezihamba ngezinyawo kanye nokwakhiwa okuqinile.
Izinzuzo ezibalulekile
I-Thermocoumplecles 'Ukuthandwa okukhuthazelayo kuvela ezinzuzweni ezinhlanu ezibucayi:

• Ububanzi bokushisa obubanzi: Ngokuya nge-alloy yensimbi, bakala kusuka ku-270 ° C (-454 ° F) kuya ku-2 300 ° C (4,172 ° C) -Uftformformformformformformformformformformformatiforming iningi lezinzwa.

• Impendulo esheshayo: Isisindo sabo esiphansi esiphansi siyabavumela ukuba babone ushintsho lokushisa kuma-milliseconds, abucayi izinqubo ezinamandla njengokuhlolwa kwenjini.

• Amandla Omshini: Ukumelana nokudlidliza, ukushaqeka nokugqwala, bachuma ezindaweni zezimboni lapho izinzwa ezibucayi zihluleka.

• Ukusebenza kwezindleko: Ukwakhiwa okulula kubenza babize imali, ngisho nokufakwa okulinganiselwe njengezitshalo zamakhemikhali.

• Ububanzi: Kuyatholakala ngocingo oluguqukayo, ama-Conses aqinile, noma amafomu wangokwezifiso ukuze avumelane nezikhala eziqinile noma izinhlelo ezihlukile.

Izinhlobo ezijwayelekile kanye nezinhlelo zokusebenza

Izinhlobo ezahlukahlukene ze-thermocouple zisebenzisa inhlanganisela yensimbi ethile eyenzelwe imibandela ethile:

Ukusuka ekubhekeni insimbi encibilikisiwe ekuqinisekiseni amazinga okushisa aqondile kuma-reactors ezemithi, ama-thermocoumpules ajwayele cishe noma iyiphi inselelo yokulinganisa.

Imininingwane Yomkhiqizo: Amapharamitha we-Premium Thermocople

Ama-thermocouples ethu ezimboni ahlangabezana namazinga aqinile aphesheya (IEC 60584, ANSI MC96.1) Ngokucacisiwe okulandelayo:

I-FAQ: Kuphendulwe imibuzo ebalulekile ye-therkocouple

Q: Ngilinganisa kanjani i-thermocouple, futhi kudingeka kangaki?
A: Ukulinganisa kubandakanya ukuqhathanisa ukuphuma kwe-thermocouple kumazinga okushisa atholakalayo (usebenzisa ukugeza okulinganiswayo noma isithando). Ngezicelo ezibucayi njengokukhiqiza amakhambi, ukulinganisa kufanele kwenzeke njalo ezinyangeni ezi-6. Kuzilungiselelo ezifunwayo (e.g., HVAC), okwanele konyaka. Iningi le-thermocouples yezimboni ligcina ukunemba ngaphakathi kweminyaka engu-1-3 ngaphansi kokusetshenziswa okujwayelekile, kepha izimo ezinzima zingadinga amasheke athe xaxa. Njalo landela imihlahlandlela ye-ISO 9001 yemibhalo yokulinganisa.
Q: Yini ebangela i-thermocouple Drift, futhi ingavinjelwa kanjani?
